I'm not sure which super test 400 your talking about, but I'm going to assume it's the same one I've seen. The s.t. is 400mg of enanthate and the t-400 is a combo of enan, cyp and prop, this is made by Denkall.
here is a blast from the past....
im starting my first cycle very soon. possible tomarrow. i was going to do Sustanon (sust) for 10 weeks. but i am considering this t-400 stuff. i hear it is painful as hell though. but denkall's site has so much info it is nearly impossible to get faked. and with Sustanon (sust) its very easy. oh i should have mentioned im going to tj. so if any one has any suggestions i sure would appreciate it.
I must give props to Denkall's website. They definitely have you covered if you are the one that will be making the trip. I have only used denkall products thus far and I was very happy w/ T-400 but you have to know there will be pain involved.
