I’m 52 and work out 5x a week, trying to stay in shape as best I can. I’m also doing my best to eat right and get my sleep. I’m torn between adding Klow or just BPC-157 & TB-500 to my current stack, which consists of Reta, CJC-1295/Ipamorelin, Semax, Selank, and SS-31. Thanks for any advice.

Semax and Selank: nasal spray or injectable — which gives you better results?
