Hangin,
I have tried inhaling bremelanotide (PT-141). I mixed a 10mg vial with 100 units of b/c water. I filled an insulin syringe with 10 units=1mg, then with a wire cutter removed the needle. I then with my head tipped back slowly pushed the plunger while inhaling up my nose just about a drop at a time for about 5 minutes. I did get stimulated in about an hour. The effect was mildly satisfactory but not near the effect of injecting or as long lasting.
I believe the peptide needs to be mixed with b/c water to make it available to be absorbed, just snorting, the powder would just sit in the nose and may not be absorbed and may even make you sneeze-what a waste!
The peptide is very sensitive so under the tongue, the heat and salivary enzymes may destroy it.
Vaginal application after mixing with b/c water may work- why don't you and partner try that method and report back. From my reading, it seems like females need a larger dose than men.
"moonvixen" a member on this form tried various methods if I remember correctly-look for her thread.
Good luck

I want the nasal option to work so bad
