Have you looked into doing these as a nasal spray instead? I tried both that way at 250-600 mcg and noticed positive effects. I have thought about adding them back sub-q and would pin them separately, Semax in the morning and Selank later in the day. Hard to say exactly when any effects faded because I was not treating specific symptoms, just trying to lift productivity and mood. Other habits like sauna and float tanks were also in the mix so results are hard to separate.
Planning to research both peptides at 300 mcg each on a 5 days on 2 off schedule, probably in the morning. Main questions are whether they can go in the same injection, what the recommended time off really is after four weeks of use, and whether symptoms return once the break starts. The research subject tends toward irritability and short temper possibly tied to low mood but does not usually feel sadness.
