here is the promo I received for steroid 4 you......the t4 will come in handy and the cutstack is something I will have to wait just a bit to use.....In My Opinion It is gonna take a little more than 5ml to get a good idea of the gear....BUT what I plan on doing is starting a cycle with some prop ace mast and then switch over to this at some point to give myself a good gauge of the potency of the gear. I know we all have our opinions but this is how I am gonna approach it....Thanks Eric for another opportunity to use your gear....all has been good so far
