<![CDATA[Nasal PT-141]]>I’m interested in researching with PT-141 and have heard some instances of using it mixed in a nasal solution. Does anyone have any experience or feedback with this method? I am thinking it would just be one less injection into the rat and more discrete also. Thanks!

Molecular weights 300 and under work best when no carrier for absorption is used. Molecular size is mentioned on page 18 of 21 on this pdf.

Tried it a couple times and then threw it away. I am a female though so maybe it's different for men
