I only have good things to say about sci-fit. Ive personally never taken the test stack, but i did take the androstack. I have nothing but good to say about it. Weight went up 5lbs, (which isnt much) BUT strength climed like crazy (which was the purpose of the cycle anyway). At the time i was stuck on 315lbs bench for 3 reps. At the end of my andro cycle my bench was 345lbs for 4 reps. Some might say its confidence, coincidense, or maybe even psycological...but hell, i didnt give a shit. whatever it was, my bench was up, and thats all i cared about. The only bad thing i can say about sci-fit is its kinda pricey (where i get it anyway).
What are you trying to get outta your cycle? weight? strength??
