ok. isnt that on the harsher sides? i have been looking into sust300 which i have ran for a very short amount of time. i was shooting 600mg a week. but that didnt last long cause i wasnt aware that test takes as long as it does to start doing its magic so i started to question its legitimacy. but i did start to notcie dramatic increases in libido, muscle definition, and deffinately stamina near the very end.
