I do all my purchases from genezameds.cc. They have always delivered and the site is very user friendly. You can get easy explanations on the supplement, and what to stack with it to get the desired result. Geneza will give you dosing guidelines and let you know what the best PCT is for when you are done to keep your gains. Customer service is lights out as well. This is where I go for all my needs, and would highly recommend to anyone needing a supplement supplier.
