Our products
BESTSELLERFACEGHK-Cu Face Serum
Anti-Aging Face Serum
0.01% copper tripeptide-1. Stimulates collagen III synthesis, elastin production, DNA repair. The signal peptide that commands skin repair.
POPULARHAIRGHK-Cu Hair Serum
Scalp & Follicle Serum
0.005% concentration targets Wnt/β-catenin pathway. Reactivates dormant follicles. Thicker strands, fuller coverage.
RECOVERYGHK-Cu Micro

What our customers say
“Skin texture changed within 3 weeks. My dermatologist noticed before I said anything.”
“I was losing hair from stress. 6 weeks in and the shedding has completely stopped. New growth visible.”
“Finally a supplier that publishes real COAs. Ordered 3 batches. Purity consistent every time.”
“The microneedling solution is next level. Combined with my dermaroller, results were visible after the second session.”
“Shoulder injury that wasn’t healing. Added BPC-157 to my protocol. Back to training in 4 weeks.”
“EU shipping, proper cold chain, Janoshik verified. This is how peptide suppliers should operate. Switched from US vendor permanently.”
“Gut issues for 2 years. GLP-2 for 8 weeks. Doctor says my inflammation markers are down 40%. Absorption has never been better.”

Research & Formulation
Collagen III Synthesis
Published research demonstrates GHK-Cu increases collagen III production by up to 300% in human fibroblast cultures. The copper tripeptide activates TGF-β signaling, directly instructing dermal cells to produce the structural proteins associated with young, elastic skin.
