I have used PT141 extensively, especially when I was on an SSRI. For those who do not know, one of the more common side effects of an SSRI is the inability to bust a nut. You can get right to the edge, that blessed point where you KNOW it is gong to happen, that NOTHING can stop you now - not even death! Then BAM, instantly soft. No release and no relief of the pressure and frustration that you feel at that moment. Whoever thought handing such a side effect to someone who needs meds for depression should be drawn and quartered...slowly...
So in my effort to finish the act, I took high doses of test, ensured my E2 and prolactin levels aere normal, and Cialis. Still no completion. I then added PT141 and that did the trick. Cialis increases blood flow, PT141 increases electrical signaling to your nether regions.
Halfwit is correct, you cannot "train" a PT141 erection - they happen when they want and damned be the consequences. Nothing better than springing a huge one (with all those drugs adding to the effect, the chubby is powerful) while doing a bench press - so it is the most obvious it could possibly be.
PT141 also lasts 2 or 3 days, with day 2 actually being a far better day, sex wise, than day 1. It is a great substance to keep in the freezer for when you think you may end up with stage fright. You know, for those times you realize you have a chance at bringing home 2 or three women...and it occurs to you that you might not have enough stamina for all of them...
