Cosmetic Grade Copper Peptide GHK-Cu 99% Pure | Anti-Aging Peptide Powder CAS 89030-95-5 for Skin Care and Weight Management

Someone mixing this into a serum base at home — they want it to dissolve clean without clumping at 5mg per ml, that's usually fine with distilled water or a simple buffer.

We've shipped to small formulators who blend it with hyaluronic acid, most don't need a full 50-gram bag anyway, but our MOQ is 10 grams and we keep the lyophilized white powder in sealed vials or foil pouches — you'll get a COA with HPLC results showing 99% or better, purity is tighter than reagent grade for this applicaion.

It basically stays stable at -20°C (check lead time if you're not set up for that) and we've seen it hold for 24 months or so in proper storage, but if you leave it at room temp for a week it'll degrade faster than you'd think — I've had buyers ask why their batch turned yellow, that's oxidation form heat.

Teh weight management angle is real but it's not a standalone fat burner — what it does is modulate adipocyte function in lab models, so think of it as a research tool for metabolism studies, not something your customers slap on their skin and expect waist loss.

Also, it's not great for wound healing if you need fast clotting effects — GHK-Cu is more about collagen stimulation over time, so dermatology labs use it for dermal matrix repair studies rather than acute injury models.

CAS 89030-95-5 might show up as blueish if copper isn't chelated properly, but ours comes as that, (roughly 403.92 g/mol) and we test each lot — one batch earlier this year had slightly lower solubility in ethanol, so stick with water for consistent results.
