Noopept Dosage and which to choose

[Zol1th]

Was researching a cognitive focus peptide and saw both semax and noopept, but heard noopept was a little better. Started looking at threads and there are so many forms to take it. There's a liquid form (drops) I saw in science bio and saw it was cheap and simple enough to take. Also saw in a thread here that there are capsules by pure nootropics and was also interested. However, I mainly saw that people use it in a powdered form? So I just want to know which way is the most effective to take. I would prefer drops and capsules since its the fastest, but which one is the correct one?
