Oct 5, 2017 I've never used caverject. No need. I have heard its crazy. A radio DJ in my city did it on air. Shits no joke. I use Melanotan-2 yearly in the summer or before vacation. I get random hardons like a teenager every time. pt-141 is mt2 with out the tanning properties. So it should work the same. I never took pt-141 as i dont "need" it. Just mt2 which is the same shit but with tanning.
