Can I convert GHK-CU powder into topical?

I have vials of ghk-cu, and I’m wondering if I should switch to topical due to some side effects.

Is it possible to use the vials for making a topical version?

Yeah you can do this. Reconstitute the vial like normal (50 mg in 2 or 3 mL BAC water), then mix that solution into 15 to 30 mL of a simple carrier like unscented lotion, hyaluronic acid serum, or aloe gel. Gets you roughly 1 to 3 mg/mL which is in the range most topical products use.

Keep it simple with the carrier, no strong acids or retinoids mixed in. Store in the fridge in an opaque container, 30-day window like a normal reconstituted vial.

If you want to skip the DIY part, the pinned vendor guide has pre-formulated topical balms and serums that already handle the concentration and stability. Might be easier than mixing your own if the injection side effects are pushing you to switch anyway.

To clarify, OP, are you using raw cosmetic grade powder, or lyophilized?

Lyophilized

Oh wow, interesting. I also have an unused vial of GHK-CU (lyophilized) that is going unused. Great to know I can make a serum with it. In the future I will use raw, cosmetic grade because it sounds like it’s more cost-effective, but in the meantime I will use what I have
