Longevity and Anti-aging Research

Epithalon

Synthetic tetrapeptide studied for telomerase activation, telomere elongation, and circadian melatonin normalisation. Originally derived from pineal gland extract by gerontologist Vladimir Khavinson. Also known as Epitalon.

From $23.164 vendors

GHK-Cu

Naturally occurring copper-binding tripeptide studied for collagen synthesis, wound healing acceleration, and broad gene-expression regulation via the proteasome system. Declines sharply with age. Available in both injectable and topical forms.

From $64.993 vendors

Weight Loss Research

AOD-9604

Modified C-terminal fragment of human growth hormone studied for selective fat-cell lipolysis without the blood sugar or anabolic side-effects of full-length HGH. Received FDA GRAS status for oral formulation.

From $45.993 vendors

CJC-1295 (with DAC)

Long-acting GHRH analogue with albumin-binding DAC modification; studied for sustained pulsatile growth hormone secretion over 6–8 day windows from a single injection. Most convenient GH-stimulating peptide for weekly dosing protocols.

From $72.993 vendors

Ipamorelin

Selective GH secretagogue studied for clean pulsatile GH release without cortisol or prolactin elevation seen with older GHRP compounds. Most commonly combined with CJC-1295 for synergistic GH secretion up to 5× greater than either alone.

From $36.993 vendors

Muscle Growth Research

IGF-1 LR3

Long-acting IGF-1 analogue with reduced IGFBP binding; half-life ~20 hours vs ~10 min for native IGF-1. Studied for satellite cell activation, skeletal muscle hypertrophy, and mTOR pathway research. Limited US availability — verify stock before ordering.

Immunity Enhancement Research

Thymosin Alpha-1

28-amino acid thymic peptide (Zadaxin® precursor) studied for T-cell maturation, NK cell activation, and vaccine adjuvant effects. Approved pharmaceutical in 35+ countries for hepatitis B/C. Most clinically validated peptide in this category.

Sleep Enhancement Research

DSIP

Nonapeptide originally isolated from sleeping rabbit blood in 1977; studied for slow-wave sleep induction and EEG delta-wave modulation. Improves sleep architecture without sedation or dependence. Very limited US availability — custom synthesis required.

Reproductive Health Research

PT-141 (Bremelanotide)

Melanocortin receptor agonist (Bremelanotide/Vyleesi®) studied for central sexual arousal pathways via MC3R/MC4R in the hypothalamus. FDA-approved for hypoactive sexual desire disorder. Acts on desire (brain) not blood flow — distinct mechanism from PDE5 inhibitors.
