My suggestion is go stop looking into Hi-tech Pharmaceuticals. If your looking for PH then you need to read the stickies provided here on this site. The fact that you don't know the difference leads me to suggest;
Protein, Creatine, possibly a test booster, lots of clean food and heavy lifting sessions.

Hi- Tech, Muscle Labs USA, Swess Pharma, any companies like this that name products a steroid are warning signs to me.

Good companies for prohormones would be CEL, LGI, Purus, RPN, and even Powerlab. But, please do research before you jump to these. (stickies and tunedsports.com are excellent sources) But as Reigner said below, creatine, protein, a DAA product, and ,maybe throw in Erase.

Another good company that is fairly cheap is hard rock supplements. You can start with their pmag and work your way up. You need to do far more research before you start though. Also, look at prohormonedb.com and primordialperformance.com under their info page and you can find all the legit prohormones and their clones. Don't jump into a big one right away, do it the right way and start with pmag or hdrol after you do your due diligence.
