i decided to stick with the masteron. but i will plan to use halotestin for my fall shows. have you ever of upjohn halo being around. would rather use 10 mg's a pill if possible. also i picked up vasopro ephadrine and im using it with Tight. how many should i be taking a day. im taking the ephedra 3x a day and so far i have only used Tight 2x a day, cant handle anymore. man i feel wacked on that stuff. pupils are dialated, heart racing, stomach cramps, shortness of breath. this is one of the reasons im sticking with masteron because i dont need anymore side effect possibilities. whats your opinion on the eca stack though?
