I am currently researching Tirz and GHK-CU. I ordered SS31, KPV, Selank and Semax. I was going to implement KPV right away in my stack. Just curious if I could add one or more of the others? I know probably shouldnt be adding to many all at once? Would you suggest SS31 during my washout period of GHKCU and KPV? Curious if anyone else has used any of these in their research. These are my first time researching anything other than Tirz.
