GHK-Cu 50mg
Glycyl-L-Histidyl-L-Lysine copper complex — the copper-binding tripeptide that modulates expression of over 4,000 human genes involved in collagen synthesis, wound healing, and cellular repair.
Copper Delivery & Gene Expression Modulation
GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex, CAS: 49557-75-7) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine — concentrations decline significantly with age (~200ng/mL at age 20 to ~80ng/mL by age 60). GHK-Cu modulates the expression of over 4,000 human genes, promoting wound healing and remodeling genes while downregulating inflammatory and oncogenic pathways. As a copper chaperone, it delivers Cu²⁺ to cuproenzymes including lysyl oxidase (collagen/elastin crosslinking) and superoxide dismutase (SOD1/SOD3). Fibroblast studies show increased synthesis of collagen types I, III, and IV, metalloproteinase activation for old collagen breakdown, and TIMP-1/2 upregulation to prevent excessive matrix degradation. Molecular weight: 340.38 Da (free tripeptide).
Research Highlights
Collagen & Skin Matrix Research
GHK-Cu stimulates collagen types I, III, and IV synthesis by fibroblasts, activates metalloproteinases for old collagen breakdown, and upregulates TIMP-1/2 to prevent excessive matrix degradation. In vitro studies show increased dermal thickness and tensile strength in treated fibroblast models.
Wound Healing
GHK-Cu accelerates wound healing in multiple animal models through angiogenesis promotion, keratinocyte migration, and anti-oxidant defense via SOD activation. It has been studied in human clinical trials for wound and ulcer healing, with demonstrated improvements in healing rate and tissue quality.
Anti-Aging Gene Expression
Microarray analysis shows GHK-Cu reverses gene expression signatures of aged skin — upregulating repair, remodeling, and mitochondrial genes while downregulating inflammatory and oncogenic pathways. Pickart's foundational research identified 4,000+ gene targets, covering approximately one-third of the human genome.

Epithalon 50mg
A synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from the natural pineal peptide epithalamin. The most studied peptide bioregulator — 40+ years of research covering telomerase activation, telomere elongation, anti-aging, melatonin regulation, and lifespan extension in rodent models. Supplied as lyophilized powder for laboratory research.

IGF-1 LR3 1mg
IGF-1 LR3 is a modified analog of Insulin-like Growth Factor-1 (IGF-1) with an extended half-life (~20–30 hours vs. ~12–15 min for native IGF-1). IGF-1 mediates many of GH's anabolic effects and declines substantially with age. Research investigates IGF-1 LR3 in cellular proliferation models, satellite cell activation, protein synthesis signaling, and the GH/IGF-1 axis in aging — a pathway closely related to epithalon's longevity mechanisms.

SNAP-8
SNAP-8 is a synthetic octapeptide (Acetyl-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2) that mimics the N-terminal end of SNAP-25, a substrate protein in the SNARE complex involved in synaptic vesicle docking. Research models use SNAP-8 to study inhibition of catecholamine release at the neuromuscular junction, which may reduce repetitive muscle contractions implicated in expression line formation. Frequently studied in topical formulation models alongside GHK-Cu.
