Compounds

GHK-Cu is a naturally occurring copper-binding tripeptide that your body produces less of as you age. Between your twenties and your sixties, levels decline by over 60%.

Sermorelin is a peptide that signals your pituitary gland to produce more growth hormone. It was FDA-approved in 1997 for children with growth hormone deficiency and was taken off the market in 2008 for manufacturing reasons, not safety concerns.

Selank is an anti-anxiety and cognitive peptide developed by the Russian Academy of Sciences, where it's been approved as a prescription medication. It's a synthetic peptide derived from tuftsin, a naturally occurring immune-regulating peptide.

Semax is a cognitive and neuroprotective peptide, originally developed in Russia for stroke recovery and now widely used there as a prescription medication. It's a synthetic peptide derived from ACTH (a stress-response hormone), designed to target the brain specifically.

Thymosin Alpha-1 (Ta1) is a synthetic version of a peptide your thymus gland naturally produces. The thymus trains your immune cells, and it shrinks as you age.

BPC-157 is a peptide studied for its healing properties, originally isolated from a protective protein in human gastric juice. It's one of the most-researched compounds in this space, with over 100 published studies on tissue repair, gut healing, and inflammation, though the majority of that data comes from animal research.

TB-500 is a synthetic version of the active region of thymosin beta-4, a repair protein your body produces naturally. It was originally studied in racehorses (where it became famous for tendon recovery), and has since moved into human research for whole-body tissue repair.

CJC-1295 without DAC (also called Mod GRF 1-29) is a short-acting peptide that tells your pituitary gland to release more growth hormone. It works with your body's natural rhythm, triggering growth hormone in pulses rather than flooding your system with a constant supply.

Ipamorelin is a selective peptide that tells your pituitary gland to release more growth hormone. It has a clean side-effect profile with minimal impact on cortisol and prolactin levels, making it well suited for body composition, recovery, and anti-aging applications.

AOD-9604 is a fragment of human growth hormone, specifically the part responsible for fat metabolism, isolated from the parts that promote cell growth. It influences how your body stores and burns fat without raising IGF-1, disrupting blood sugar, or triggering the growth effects that make full growth hormone problematic for long-term use.

KPV is a small anti-inflammatory peptide, derived from a naturally occurring hormone your body already makes. It reduces inflammation and fights microbes without the skin-darkening side effects of the full hormone.

MOTS-c is a peptide produced by your mitochondria. It acts as a hormone-like signal that helps regulate your metabolism, enhance insulin sensitivity, and promote longevity.

Epitalon is a small synthetic peptide based on a compound your pineal gland produces naturally. The two things people typically notice first: improved sleep quality (from increased melatonin production) and a general sense of cellular renewal (from telomerase activation, which maintains telomere length).

Kisspeptin is the peptide your brain uses to control reproductive hormones. It sits at the top of the chain, signaling the release of GnRH, which triggers testosterone and estrogen production downstream.

DSIP (Delta Sleep-Inducing Peptide, listed by the FDA as Emideltide) is a short, naturally occurring peptide first isolated from the blood of sleeping rabbits in 1974. It's the oldest compound on the FDA's July 2026 review agenda by date of discovery.
