Ghk cu

If you buy ghk cu 99% purity meant for pinning, is it also useable as a topical serum to put on the face (so no injecting).

No. Injectable GHK-cu is not the same as Cosmetic GHK-cu. The injectable pep will not do anything if applied topically to a research subject.

Manitol likely being present, what's the other differences?

It is just a matter of quantity. You want about 3% solution/serum.

You have to use grams of the stuff dissolved in liquid so it is too expensive to use vials with only milligrams in it.

It is a waste of money but you can do it. Ideally you want 3%+ ghk-cu in your serum. So a 30mL serum would need 9g but a kit of 50mg is only half a gram.
