Mots-C: Unveiling the Hidden Elixir for Weight Loss, Mitochondrial Efficiency, and Enhanced Athletic Endurance

Mots-C: Unveiling the Hidden Elixir for Weight Loss, Mitochondrial Efficiency, and Enhanced Athletic Endurance

Introduction

In the ever-evolving world of health and fitness, researchers are continuously exploring novel avenues to optimize weight loss, boost mitochondrial function, and enhance athletic performance. One promising candidate that has recently garnered attention is Mots-C, a lesser-known peptide with profound potential benefits. This blog post aims to shed light on the science behind Mots-C and its implications for weight management, mitochondrial efficiency, and athletic endurance, drawing evidence from clinical studies.

Mots-C: Unraveling the Science

Mots-C, short for Mitochondrial-derived peptide-c, is a small protein encoded in the mitochondrial DNA. Initially discovered in 2015, this enigmatic peptide has since captivated researchers due to its seemingly multifaceted effects on human physiology. Studies have shown that Mots-C may play a crucial role in regulating metabolism, mitochondrial function, and cellular energy production.

Weight Loss: A Metabolic Marvel

Clinical studies have investigated the potential impact of Mots-C on weight loss and metabolic regulation. A study conducted by Lee et al. (2016) on mice revealed that elevated levels of Mots-C led to improved insulin sensitivity and enhanced glucose metabolism, ultimately resulting in reduced body weight and fat mass. While more research is needed to fully understand its effects on human metabolism, these findings suggest that Mots-C holds significant promise in the battle against obesity.

Mitochondrial Efficiency: Fueling the Powerhouse

The mitochondria, often referred to as the cell's powerhouse, play a central role in energy production. Mots-C appears to influence mitochondrial function, promoting efficiency and cellular health. In a study conducted by Kim et al. (2018), researchers observed that Mots-C treatment increased mitochondrial oxygen consumption and ATP synthesis, enhancing overall cellular energy production. By enhancing mitochondrial function, Mots-C has the potential to improve overall energy levels and endurance.

Enhanced Athletic Endurance: Unleashing the Hidden Potential

Athletes and fitness enthusiasts are always on the lookout for ways to enhance their performance. Mots-C may offer a groundbreaking solution. Research conducted by Liu et al. (2019) demonstrated that Mots-C administration in mice led to increased exercise endurance, attributed to enhanced mitochondrial function and improved metabolic efficiency. While human trials are yet to be conducted, these preliminary findings hint at the possibility of Mots-C being a game-changer in the athletic world.

Conclusion

Mots-C, the mitochondrial-derived peptide, holds incredible promise as a catalyst for weight loss, improved mitochondrial efficiency, and enhanced athletic endurance. Preliminary studies on animals have indicated encouraging results, but further research is required to fully understand its effects and potential side effects in humans. As with any emerging scientific breakthrough, caution and rigorous investigation are essential before adopting Mots-C as a supplement or therapy. Nevertheless, the findings so far make Mots-C a fascinating subject of exploration in the quest for better health and athletic performance.

Hollywood’s New Secret to Losing Weight is a Diabetes Injection

Last month, Variety reported that the drug had become a crucial part of many celebrities preparation before making public appearances.

It was even said by an anonymous source that it was so prevalent that it was comparable to getting a star's hair or makeup done before an event.

What this medicine does is help patients adhere to a reduced-calorie diet. With obesity, you always need lifestyle changes plus the medicine.” Semaglutide is part of a class of medications called GLP-1 receptor agonists, or glucagon-like peptide-1 receptor agonists. It increases insulin secretion, which is good for diabetes. But at higher doses, it acts on centers in the brain and suppresses appetite. It is important to use this medication in conjunction with lifestyle intervention. Additionally, semaglutide has been shown to be cardioprotective — they prevent heart attacks, and they protect kidney function as well, which is important for diabetics.

We have not seen this degree of weight loss with any previous medication,” said lead study author Dr. Timothy Garvey in a statement. “More than 50% of trial participants are losing 15% of their body weight, and anywhere between a third and 40% of participants are losing 20% of their body weight.”

Side Effects:

  1. nausea

  2. diarrhoea

  3. vomitting

  4. abdominal pain

  5. decreased appetite

The gastrointestinal side effects may be experienced by 10% of people using semaglutide. The feeling is similar to the sensations felt if a person really over eats.

Thymosin Alpha 1

Thymosin Alpha-1 is a protein which consists of 28 amino acids. Thymosin Alpha-1 is believed to be a significant component of Thymosin Fraction 5 responsible for the activity of that preparation in repairing immune function. It has been found to improve cell-mediated immunity in humans. Thymosin Alpha-1 plays a vital role in the control of immunity, tolerance, and inflammation. It manages immune response via an initial action on the cells of the innate immune system and thus acts as an endogenous regulator of both inflammatory and adaptive immune responses. Thymosin alpha-1’s immunomodulatory activities are centered primarily on the augmentation of T-cell function.

Thymosin Alpha-1 has been used to treat diseases:

• Immune Dysfunction

• Hepatitis B virus (HBV)

• Hepatitis C virus (HCV)

• Certain types of cancers

• Arthritis

• Rheumatoid arthritis (RA)

• Systemic lupus erythematosus (SLE)

• Chronic Fatigue

• Lyme's Disease

• HIV/AIDS

• Autoimmune diseases

Keep Yourself Away From This Oil: It’s More Dangerous Than a Sugar!

Generally people believe that adding this oil in order to prepare their meals is healthy. But that actually is wrong!

Although soy seems to be desirable alternative to most foods due to their advertised health benefits, the truth is quite different. In fact, soybean oil can do more harm than profit.

Soybean oil, as well as all soy products, are derived from soybeans. Still, most manufacturers do not mention soybean is toxic in nature.

In order to become edible, soybeans require large treatment.

In addition, too much soy can provoke the body to produce steroid hormones, increased risk of developing Alzheimer’s disease and early puberty in girls and delayed physical maturation in boys.

Another shocking fact is that there is big production of GMO soybeans all over the world which makes it impossible to completely avoid them.

It is quite surprising that soy milk is recommended for infants instead of breast milk from their mothers. This actually is the biggest absurdity.

However, soy industry and soy producers are powerful people who will never admit what lies behind those products and what actually we are buying.

What is IGF-1 and why is it important?

The primary purpose of IGF-1 is to stimulate cell growth. Every cell in the human body can be affected by IGF-1, but cells in muscle, cartilage, bone, liver, kidney, skin tissue, lungs, and nerves tend to be most positively affected.

Several scientific tests have been conducted to determine the benefits of IGF-1 and thus have prompted companies to seek approval from the Federal Drug and Administration for substances that can increase the body's IGF-1 levels. IGF-1 can also stimulate a decrease in body fat, an increase in lean muscle mass, improved skin tone and restful sleep. IGF-1 has also been documented to increase the rate and extent of muscle repair after injuries or strains. Not only do muscles recover more quickly, they also tend to return stronger and healthier than ever when levels of IGF-1 in the bloodstream are at their highest.

Many believe that (IGF-1) is the key factor in muscle growth. It is released from the liver during times of high insulin and high GH (growth hormone) levels. I will repeat, to stimulate the production if IGF-1, GH levels and insulin must be high simultaneously. This is the problematic part because when insulin levels are high, GH is normally kept low.

This is another reason why insulin levels must be consistently controlled. Insulin levels must be raised at specific times to promote enhanced growth and IGF-1 production. For example, to make IGF-1 work for you after a hard workout of 45 minutes your GH levels will be very high so If you then eat a high carb/high protein meal, you will cause a rise in insulin levels, which will cause the release of IGF-1.

IGF-1 is not released during times of low insulin levels. Low insulin and low IGF-1 levels are the primary reasons it is difficult to gain muscle on low-carb diets. It should be noted to that low pro­tein intake also causes a decrease in IGF-1 levels. 

One must be careful not to have too much supplemental IGF-1 in the body or side effects can occur. When too much synthetic IGF-1 is present one can experience jaw pain, facial, hand, and heart swelling. Heart swelling can lead to higher blood pressure and heart failure. Synthetic IGF-1 stays in the body longer than natural IGF-1 and because IGF-1 produces growth cells it can lead to muscle and organ overgrowth. References to bodybuilders and power lifters with abnormally large stomachs have been linked to overuse of IGF-1 because their internal organs have grown too large. Lastly, if free roaming IGF-1’s stay in the body too long there has been evidence to show that it can produce different cancers.

So, in a nutshell, IGF-1 is a great hormone that your body produces naturally. It is an amazing compound that helps with cellular growth and repair throughout the body. It helps our bodies grow to their natural state as well as aids in the building and repairing of muscles. But one must be careful when using synthetic IGF-1 for bodybuilding purposes, not to over do it. In my opinion the side effects of overuse do not outweigh the results. Again, the saying “You can’t have your cake and eat it too!” comes to mind.

New Study Appears to Suggest Benefits from Testosterone in Elderly Men

Salt Lake City, UTMuch has been written about testosterone side effects and especially adverse reactions that affect the heart. While testosterone therapy is indicated for individuals with severe testosterone depletion (hypogonadism), the recent advent of testosterone as a pathway to the fountain of youth has resulted in numerous men who arguably are not in medical need of testosterone supplementation, allegedly suffering debilitating cardiovascular injuries such as testosterone stroke, amongst other adverse reactions.

But now there is a study that appears to suggest that elderly men with low testosterone and pre-existing coronary artery disease can benefit from testosterone through a reduction of risk for cardiovascular events, including stroke, heart attack and death.

The multi-year study was conducted by the Intermountain Medical Center Heart Institute, based in Salt Lake City, Utah. The research team was to have presented their findings this past Sunday (April 3, 2016) at the American College of Cardiology’s 65th Annual Scientific Session.

“The study shows that using testosterone replacement therapy to increase testosterone to normal levels in androgen-deficient men doesn’t increase their risk of a serious heart attack or stroke,” said cardiologist Brent Muhlestein, MD, co-director of cardiovascular research at the Intermountain Medical Center Heart Institute. “That was the case even in the highest-risk men - those with known pre-existing heart disease.”

The study appears to add a new chapter to everything we know about testosterone supplementation beyond the FDA-approved indication for hypogonadism. Prevailing wisdom suggests that testosterone overload can result in an over-production of red blood cells, which can thicken the blood and lead to testosterone side effects such as testosterone stroke. While the US Food and Drug Administration has always maintained there was some risk with use of testosterone supplementation, the benefit was nonetheless thought to outweigh the risk for those men suffering from severe depletion of testosterone - which by itself can have serious health consequences.

The difficulty with the current testosterone supplementation environment - the advent of the so-called “Low-T” condition - is the use of testosterone as a response to low libido or sagging energy that is a natural byproduct of aging. Clever marketing on the part of testosterone manufacturers has appealed to men’s vanity, with the result that thousands of men who otherwise do not have medically supported or diagnosed testosterone depletion are taking testosterone without knowing that an over-abundance of testosterone in an otherwise healthy man could result in a testosterone heart attack, and even testosterone death.

Many a testosterone lawsuit has been founded on that very premise.

The Intermountain Medical Center study makes no attempt to discount the risks of testosterone therapy in otherwise healthy, middle-aged men. And, in fact, The new study corroborates the findings of a 2015 Intermountain study, which found that taking supplemental testosterone didn’t increase the risk of experiencing a heart attack or stroke for men who had low testosterone levels and no prior history of heart disease.

However, the research nonetheless appears to suggest a benefit for elderly men with pre-existing cardiac disease.

A total of 755 participants at hospitals within the Intermountain Healthcare system were studied over a period of years. Study participants ranged in age from 58 to 78 and all suffered from some form of severe coronary artery disease.

According to Science Daily (4/3/16), study authors concluded that after one year, 64 patients who weren’t taking testosterone supplements suffered major adverse cardiovascular events, while only 12 who were taking medium doses of testosterone and nine who were taking high doses did.

After three years, 125 non-testosterone-therapy patients suffered major adverse cardiovascular events, while only 38 medium-dose and 22 high-dose patients suffered similar reactions.

“Although this study indicates that hypo-androgenic men with coronary artery disease might actually be protected by testosterone replacement, this is an observational study that doesn’t provide enough evidence to justify changing treatment recommendations,” Dr. Muhlestein said. “It does, however, substantiate the need for a randomized clinical trial that can confirm or refute the results of this study.”

While the aforementioned is useful information for those men of advanced years with pre-existing coronary disease, it nonetheless takes nothing away from testosterone side effects lawsuits filed by otherwise healthy, middle-aged men with no history of cardiovascular issues, whose use of testosterone supplements proved to have negative impacts on their health. Many plaintiffs suggest they were not made aware of the potential dangers of testosterone supplementation, and allege a testosterone heart attack or testosterone stroke was brought on needlessly.

GAC Performance Injections

Glutamine 25mg/ml is one of the most common amino acids in human muscle and the most abundant protein in muscle tissue. The amino acid is needed to synthesize protein and transporting nitrogen between tissues. Glutamine is needed by the body in times of extreme physical activity and when your immune system is fighting off an illness. Claims: Improve rapid water absorption, stimulation of muscle protein synthesis and muscle tissue growth, increased immune system and prevention of infection, reduction in muscle soreness and improved muscle tissue repair, and helps burn more fat while preserving the muscles and minimizing discomfort. Intense training will drop plasma glutamine levels and low levels of glutamine have been a contributing factor in athletic overtraining syndrome and an increased risk for infection that effects athletes during training and competition. Validity: Glutamine is thought to be relatively safe and well tolerated, yet is not recommended for those with kidney disorders. Excessive doses may cause gastrointestinal problems. 

L-Arginine 100mg/ml is the biological precursor of nitric oxide

Claims: Many protein powders and energy shakes contain this amino acid, marketing it as a nitric oxide producing, muscle-building supplement. Nitric oxide, in theory, is thought to be useful to athletes as it opens the blood vessels allowing for greater circulation of oxygen to all the organs, muscles, and internal systems. Additionally, it is said to stimulate the release of human growth hormone which in turn will increase muscle growth and strength. Arginine is a protein synthesis and is necessary for the proper function of burning fat and is excellent in would healing and bone repair. Claims: Marketed to enhance muscle growth, strength, and to jump start the immune system.

L-Carnitine 250mg/ml is made from several amino acids in your body, mainly lysine and methionine. It is a vitamin-like substance important for fatty acid transport.  Claim: In theory, supplementing carnitine will increase glucose metabolism, VO2 max, and reduce lactate production during high intensity exercise. However, the most important claim resides in the fact that carnitine is a “fat burner”, increasing fat metabolism and decreases fatty build up. Endurance athletes use this supplement In order to spare muscle glycogen by the relying of fat oxidation. 

The formulation of the three together are believed to provide an energy producing, fat burning, & muscle building pathway to your goals.

Foods that can naturally boost testosterone levels

Is there really such a thing as a magic shot or pill?  For some, testosterone replacement therapy may be the closest thing.  However, appropriate balance should also incorporate specific lifestyle changes. The first step is evaluating diet.  A recent article by Onegreenplanet.org does a nice job of listing 5 Plant Based Foods that Boost Testosterone in the body.

Does having children cause low testosterone?

Okay, you just had a couple of kids and you're really starting to feel the toll on your psyche.  That lethargic feeling from the non-stop hustle of changing kid's clothes, never ending pile of dishes, doing the school runs, and coaching soccer.   Oh, don't forget about your significant other, the Monday morning work meeting and all the other workplace performance metrics you are going to be measured by for your upcoming review.  Well, according to one study*, if that scenario represents a fraction of your life, you may have experienced a significant drop in testosterone.  The direct link isn't necessarily having children, but it is with how actively involved men are with daily parental duties.  

The sample size of the study was 624 men.  The original testosterone sample was taking from men that were 21 years of age.  A second testosterone sample was taken again when those same men reached age 26.  The study also noted that both samples were taken from the men in the morning, which is typically when the body's testosterone is at its peak.  Segmentation of the group was based upon those that didn't have children, Fathers that had children, but were NOT actively involved, and those fathers who spent more than 3 hours a day with parental duties.  

The data showed a strong causal link exists between high testosterone and mating success.  However, with success in mating and having children, the largest drop in testosterone came from those fathers actively involved in parental activities (26%-34% reduction in testosterone compared to non-fathers)!  One may hypothesize the reason for the decline is a nature vs nurture or as men move away from traditional hunter-gather roles to  more nurturing roles of present day.

Get your levels checked and live a more balanced life!

Adult growth hormone deficiency and why Sermorelin.

Maintaining a proper hormonal balance is a great way to head off some manifestations that we all experience with aging.  Adult growth hormone deficiency  is medical condition that exists when the body simply does not produce adequate levels of growth hormone.  This can be due to several causes, but primarily due to damage to the pituitary gland and genetic issues.  There are some instances where there is no obvious cause for the deficiency exists and that is said to be idiopathic.  

Symptoms:

  • Increased abdominal fat
  • Reduced vitality & energy
  • Poor general health
  • Reduced strength
  • Depressed moods & anxiety

The test for GH deficiency:  Since GH is rapidly converted to IGF-1 (Insulin like growth factor - 1 or Somatomedin-C) and can not be easily measured directly.  The test for hGH is IGF-1 levels, with ideal ranges being between 200-300 ug/ml.  Growth hormone deficiency is then typically defined by IGF-1 levels below 160 ug/ml.

Due to the cost prohibitive nature and the legality of growth hormone, Sermorelin has become a viable option utilizing amino acids to stimulate the body's own natural production of growth hormone.  Dr. Novins explains that sermorelin is not growth hormone, but two naturally occurring amino acids that communicate with the pituitary gland to make additional growth hormone. Since the increased volume of human growth hormone (hGH) is produced by the body's own pituitary gland, the body will not allow too much hGH to be produced by Sermorelin GHRP6 than what it can safely process.  This eliminates the potential side effects that comes with over dosing of direct injections of hGH.  

The benefits of Sermorelin GHRP therapy may include an increase in lean muscle mass, stronger joints, connective tissue, and bone density, improved mood, mental state, energy, improved libido, increase in sleep quality, and a decrease in body fat.  The outward benefits that are clearly visible come in the form of an overall improvement in skin quality.

Patients are prescribed Sermorelin are able to safely administer subcutaneous injections in the privacy of their own home.

Does Testosterone Increase Risk for Heart Attacks?

Life Extensions Magazine has released a series of points that outlines specific flaws with an original study on Testosterone increasing incidents of heart attacks. 

"This study was designed by physicians who apparently don’t know how to safely restore testosterone levels in aging men.

The media’s portrayal of this flawed study will discourage aging men from properly restoring their testosterone levels. To help spare the lives of testosterone deficient men, we have prepared an extensive rebuttal to this erroneous report.

Life Extension’s official response, starting below provides a detailed point-by-point rebuttal to the many defects in this study that was used to discredit natural testosterone restoration".
