Strength and Endurance Peptides

Peptides for Strength & Lean Muscle Mass

If you’re looking to gain lean muscle or increase your strength when in the gym, there are physician prescribed peptides that are used for their effect on an athlete’s muscle mass. Peptides can assist in reaching the goal of growing bigger muscles, possible. They also help to burn body fat, improve muscle recovery and slow aging. In addition, many also use peptides such as Melanotan II to achieve a sun tanned body, without the damage of UV rays.

Each peptide has specific purposes for which it is more useful. These compounds are in many cases beneficial because of how they boost release of growth hormone by the pituitary gland. GH secretion is amplified when GHRH and GHRP substances are used together. (GHRH means growth hormone releasing hormone and GHRP means growth hormone releasing hexapeptide, a type of growth hormone releasing hormone). Essentially, peptides cause hypertrophy (increase in size of muscle cells) and hyperplasia (increase number of cells). It increases number of muscle cells as a downstream effect, promoting lean muscle gain. This is perhaps the primary reason why many of fitness enthusiasts, body builders and athletes follow a program combined with peptides.

Please Note: Some peptides and peptide hormones to enhance athletic activity are banned by the World Anti-Doping Agency. If you are an athlete in any form of competition, the responsibility is yours to refer to their regulations and abide by them). When completing your medical history and during your consultation with one of our medical doctors, it is important to share all details with him/her, especially if you are in a competition sport.

Perhaps, the primary reason why peptides are used in bodybuilding has to do with how they improve growth hormone production. It is no secret how HGH helps to improve lean muscle mass. Your body uses peptides to promote increased secretion of HGH. The result, is a faster and more prominent increase in lean muscle mass. As such, peptides are prescribed to assist in increased strength, lower body fat and boost testosterone production.

Among the many reasons why bodybuilders use peptides is their ability to help you recover faster. They can assist in generating oxygen available to the muscle cells in sufficient amount. They can also improve your level of endurance and help to burn visceral fat.


Is a synthetic GHRH (growth hormone releasing hormone) analogue made up of 30 amino acids. It has been found to be highly effective with regards to the increase of growth hormone secretion and IGF-1 without negatively affecting the pulsatility of GH secretion. CJC-1295 is often combined with Ipamorelin due to its enhanced specificity as a GHRH. This peptide generates similar increases in growth hormone secretion, but without the appetite stimulation and increase in cortisol, acetylcholine, prolactin, and aldosterone seen with other peptides in its class. This peptide has been found to be very well-tolerated and perfect when combined with Ipamorelin as it creates a synergistic effect.


  • Increases growth hormone secretion and IGF-1 Levels with no increase in prolactin
  • Promotes Muscle Growth
  • Promotes Fat Loss
  • Increased Cellular Repair and Regeneration
  • Promotes slow wave deep sleep
  • Promotes clearer memory focus

Sermorelin: A Secret Weapon

Sermorelin, a growth hormone releasing hormone (GHRH) helps encourage the production of HGH, testosterone, and other hormones, producing a plethora of benefits.

Commonly prescribed peptides for strength and endurance

Among the most commonly prescribed peptides for strength, endurance, lean muscle and muscle mass, in coordination with a medically supervised program are:


Insulin-like growth factor is a highly anabolic hormone that is released in the liver as well as in the peripheral tissues in response to the GH so that a new muscle could be built. The main work of IGF-1 is to build new muscle tissues by promoting nitrogen retention and protein synthesis. It differs from original IGF-1 in that it possesses an arginine instead of a glutamic acid and also has an additional 13 amino acids. As a result, it is approximately three times more potent than IGF-1 and possesses a significantly longer half-life of about 20–30 hours (comparative to IGF-1’s half-life of about 12–15 hours).

Benefits of IGF1-LR3

  • Increases growth hormone secretion and IGF-1 Levels with no increase in prolactin
  • Promotes Muscle Growth
  • Promotes Fat Loss
  • Increased Cellular Repair and Regeneration
  • Promotes slow wave deep sleep
  • Promotes clearer memory focus


The peptides CJC-1295 and Ipamorelin combined, provides both a growth hormone releasing hormone (GHRH), or amplifier, and a growth hormone releasing peptide (GHRP), or inducer. This combination will promote the increase of growth hormone (GH) and is effectively used for anti-aging purposes as well as those with inflammatory conditions, disease or those who have low IGF-1 levels.

  • By stimulating the production and secretion of GH, helps increase lean muscle mass, build strength and decrease body fat.
  • Increased fat metabolism, which can lead to overall improvements in body composition.
  • Can assist muscle recovery from workouts, which allows for faster progression and typically more fat loss.
  • Anti-aging properties, including improvements to sleep, energy, mood, bone density, immune function, and body composition.

Benefits of CJC-1295/Ipamorelin

  • Decrease body fat
  • Improve sleep quality
  • Increase cognitive function
  • Quicker recovery times post-injury
  • Increased muscle mass
  • Increase in strength


Ipamorelin is one of the latest and greatest peptides in the growth factor family. Deemed one of the safest GHRP’s, Ipamorelin is a secretagogue (a substance that causes another substance to be secreted) and Ghrelin receptor agonist (promotes secretion from cells in the stomach and is important in appetite regulation and food intake). Ipamorelin is a 3rd generation GHRP and is regarded as the cleanest of the GHRP’s.

While taking Ipamorelin, your body’s natural chemistry shifts into a state where it must turn to fat as its primary fuel source, (and IGF-1 elevation) and enhances your metabolic activity / gastric motility leading to more calories being burned overall. Ultimately, this leads to an optimal state (what the body thinks is ghrelin) making your body work like a well-oiled machine. Ipamorelin’s long lasting effects include maximizing the full potential of body by working with its natural chemistry. Perhaps you are already doing regular, intense physical training, but you can improve your results with Ipamorelin. It promotes strength, growth, energy and vitality that last for hours. By taking Ipamorelin, you are using the physical processes of your body to achieve your dream body. The best thing about it is that you won’t experience any adverse side effects.

Ipamorelin can also be used to achieve a more youthful and energetic state though long-term use (6-12 months).


MK-677 is a hormone secretion compound that stimulates the pituitary gland to increase the production of human growth hormone. Ibutamoren is long-acting, orally-active, selective, and non-peptide agonist of the ghrelin receptor and a growth hormone secretagogue, imitating the growth hormone (GH)-stimulating action of the endogenous hormone ghrelin.

Benefits of Ibutamoren/MK-677

  • Increase IGF-1 Levels in as little as two weeks
  • Longer REM sleep and shorter sleep latency
  • Increase fat-free muscle mass
  • Decrease body fat percentage
  • Stronger bones
  • Improved endurance
  • Increase nitrogen levels in the body
  • Reversal of nitrogen wasting

Peptides vs Steroids

Peptides vs Steroids Simply put, peptides are simply sequences of amino acids, whereas steroids are synthesized steroid hormones. The use of anabolic steroids can lead to addiction, infertility, high cholesterol, increased risk for heart disease, high blood pressure, water retention, increased anger, body pains and withdrawal. Peptides have very little to no side effects and while they may not produce the vascular look and production, they offer muscle and strength building benefits, lean muscle mass, immune system building, increased sleep, along with other positive health benefits.
