QSC RESEARCH COMPOUND GUIDE
GHK-CuCollagenBPC-157Wound Healing
Skin research encompasses collagen synthesis, wound healing, anti-ageing mechanisms, melanogenesis, anti-wrinkle neuromuscular junction biology, and cosmetic peptide science. QSC supplies research compounds across all these cutaneous mechanisms.
What is GHK-Cu and why is it the primary skin peptide?
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide that regulates over 1000 genes. In skin, it stimulates collagen I, III, IV, and V synthesis, regulates MMP/TIMP balance, and promotes dermal fibroblast activity. It is the most data-rich cosmetic peptide in the QSC catalog.
How does Snap-8 work for anti-wrinkle research?
Snap-8 mimics the N-terminal sequence of SNAP-25 and competitively inhibits SNARE complex assembly — reducing acetylcholine vesicle fusion at facial neuromuscular junctions. This attenuates muscle contraction amplitude in a reversible, non-enzymatic manner analogous to botulinum toxin A.
What is the difference between Melanotan I and Melanotan II for melanogenesis?
Melanotan I (afamelanotide) is MC1R-selective — stimulates melanin production without significant MC4R activity. Melanotan II activates MC1R, MC3R, and MC4R — producing melanogenesis plus libido/sexual function effects. For pure melanogenesis research without MC4R effects, Melanotan I is the cleaner tool.
What formats does QSC supply skin research compounds in?
Lyophilised research vials, ≥99% HPLC purity, Janoshik COA. Ships from domestic warehouses in USA, EU, UK, Canada, and Australia.
