What got worse for some people
In their own words
“PT141 works great. I use 133mcg a day and my BP/HR are mostly unphased, I get a little bit of nausea, no tanning.”
“I have tried pt-141, 3 shots of 500mcg, and were great, I tried 1mg and had terrible side effects.”
“Only personal complaint is that it works too well. I was worried I was gonna have to go to the ER due to an erection that lasted through the night and into next day.”
“I use 3.5mg when I use pt-141 as a man. Anything less I don’t feel the effects. It increases libido and erection quality.”
“I tried it a few years ago pinning 1mg per dose and it did nothing for me.”
“Works well for me (58m). But I have to reserve it for special occasions. It’s like it crams 2 weeks of libido into 24 hours.”
