    Pt141 10mg works very fast and has a very long lasting effect well into the next day. I didn’t need to use along side any other “blue pill” type of product.

  187. Steven Saxton –

  188. Anonymous –

    Damn, son! This stuff is powerful. Took it for the first time and started to feel the effects within one hour. To be honest, I think I took a high dose. Start small and work up if needed. I was skeptical for sure, but the purity of this peptide is 100% legit. Twelve hours of high libido is no joke.
