I'm wondering if it is possible to mix the 7% GHK-Cu Accelerant into the TTT 2x and use this as a serum and would it mix well together ?

Dear winter:

Oh yes! We have many clients who mix the two together and like it very much

How much would I put into the TTT of the 7% GHK-Cu Accelerant ?

Depends on what type of results you are aiming for (--- the online calculator will assist greatly---).

But most clients seem to really like adding anywhere from 20-50 drops of the GHK Accelerant. For very sensitive skin, we'd recommend starting out with a much lower concentration... but for yourself, try 20 drops, mix into a smaller container so the you can test it, shake each time before use, and use regularly!
