GHK-Cu

Anti-Aging & LongevityHealing & Recovery

GHK-Cu (copper peptide) is a naturally occurring tripeptide with a strong affinity for copper(II) ions. First identified in human plasma by Dr. Loren Pickart in 1973, GHK-Cu concentration declines with age. It has become one of the most studied peptides in dermatological and aging research, with applications spanning skin biology, wound healing, and gene expression modulation.

Thymosin Alpha-1

Immune & Inflammation

Thymosin Alpha-1 (Ta1) is a 28-amino acid peptide originally isolated from thymic tissue by Allan Goldstein at the George Washington University in the 1970s. It is one of the most extensively studied immunomodulatory peptides, with a substantial body of research spanning several decades. A synthetic version (thymalfasin) has been approved as a pharmaceutical product in over 35 countries for various indications.

Selank

Nootropic & CognitiveImmune & Inflammation

Selank is a synthetic peptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is based on the naturally occurring immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg), with an added Pro-Gly-Pro sequence that enhances stability against enzymatic degradation. Selank has been the subject of extensive preclinical research as both a nootropic and immunomodulatory compound.

CJC-1295

Growth Hormone Secretagogues

CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) consisting of 29 amino acids. It was developed by ConjuChem Biotechnologies and exists in two research forms: with and without Drug Affinity Complex (DAC). The DAC-modified version binds to albumin, dramatically extending its half-life. CJC-1295 is one of the most studied growth hormone secretagogues in preclinical research.

Epitalon

Anti-Aging & Longevity

Epitalon (also spelled Epithalon) is a synthetic tetrapeptide based on the naturally occurring peptide epithalamin, which is produced by the pineal gland. Developed by Professor Vladimir Khavinson at the Saint Petersburg Institute of Bioregulation and Gerontology, Epitalon has been the subject of extensive research into telomerase activation, telomere biology, and age-related biomarkers in preclinical models.

MOTS-c

Anti-Aging & LongevityImmune & Inflammation

MOTS-c (Mitochondrial Open Reading Frame of the Twelve S rRNA type-c) is a mitochondria-derived peptide discovered by Dr. Changhan Lee at the USC Leonard Davis School of Gerontology in 2015. As one of several recently identified mitochondrial-derived peptides (MDPs), MOTS-c is encoded in the mitochondrial genome rather than the nuclear genome, representing a novel class of signaling molecules.
