Nasal delivery skips reconstitution completely. These arrive pre-mixed in 10ml bottles at a stated concentration, which removes the single biggest source of error in peptide research — the mixing step. The nootropic peptides in particular (Semax, Selank) have a long history of intranasal use in the Russian clinical literature, which is where most of the published work on them lives.
Both nootropic peptides pre-blended — the most common stacking request, solved in one bottle.
Melanocortin agonist acting centrally rather than vascularly. 20mg vial or 2mg/ml nasal spray.
Three-compound nasal blend — no reconstitution, no injection. 10ml bottle.
