<p>Before choosing - it's worth honestly answering the question: what needs to be addressed? A clear goal helps narrow the list down to two or three peptides.Recovery The classics in this category are BPC-157 and TB-500. Both accelerate tissue regeneration, but work differently.

BPC-157 - a fragment of a protective protein that the body produces in the GI tract. In studies, demonstrates effects on damage to joints, ligaments, tendons and mucous membranes. Additionally protects the stomach and intestines.

TB-500 - the active fragment of the protein Thymosin Beta-4. Accelerates muscle healing, improves mobility in damaged areas, reduces inflammation. In studies, demonstrates effects with systemic damage when recovery is needed in several places at once.

They are often used together - the effects complement each other.Fat loss Two main options: AOD9604 and GLP-1 agonists. AOD9604 - a fragment of growth hormone responsible specifically for fat metabolism. Stimulates fat breakdown, does not affect insulin levels and does not give the anabolic effect of growth hormone.

In research, applied for targeted work with fat tissue. GLP-1 agonists (semaglutide, tirzepatide, retatrutide etc.) - reduce appetite, slow gastric emptying, improve insulin sensitivity.Sleep Epithalon normalizes circadian rhythms through its effect on the pineal gland. This is the gland that regulates melatonin production.

In research on sleep regulation, studied in the context of disrupted sleep schedules, chronic sleep deprivation and age-related sleep changes. An additional bonus is its anti-aging effect through telomerase activation.Epithalon is one of the most studied anti-aging peptides. Activates telomerase, slows telomere shortening, normalizes hormonal background and improves sleep quality.

Courses are usually short - 10-20 days, 1-2 times a year.Skin GHK-Cu - a copper tripeptide, one of the most researched peptides in dermatology. Stimulates collagen and elastin production, accelerates healing, reduces wrinkle depth, evens skin tone, speeds up cell renewal and reduces systemic inflammation - one of the markers of aging. Works both systemically (injections) and locally (cosmetics).Immunity Thymus peptides - Thymalin, Thymosin Alpha-1, Thymogen.

In studies, demonstrate effects on restoration and regulation of the immune response, particularly when it is reduced. Thymosin Alpha-1 - the most studied of this group. BPC-157 also has an anti-inflammatory effect and indirectly supports the immune system through protection of the GI mucosa - the first barrier of immunity.Muscle mass and growth hormone Two classes of peptides work here - GHRH and secretagogues (GHRP).

GHRH (CJC-1295, Sermorelin) - mimic the hypothalamus signal, stimulate the pituitary gland to produce growth hormone. Act gently, supporting the natural rhythm of secretion. Secretagogues (Ipamorelin, GHRP-2, GHRP-6) work through ghrelin receptors, also boosting growth hormone release.

Ipamorelin is the cleanest option without extra influence on cortisol and prolactin. The GHRH + secretagogue combination gives a synergistic effect and is considered one of the most effective schemes for mass gain and body composition improvement.</p>
