If you want the GOAT supplement, go with hcgenerate. It not only works great for libido, erections, and testosterone boosting but it also has ingredients to help you with things like cholesterol.
Tren is the goat. It's going to really give you some amazing results. I would run it like this: Tren ace 50mg every other day. Stack in some Anavar with it and make sure you use N2Guard with it.
