The real question you need to ask yourself before taking any enhancers like this is - Have you reached your genetic peak..

A study was done using advanced training techniques of around 30 - 40 average men, and they found that with the right training and diet, nearly every one of those men acheived their genetic peak as far as bulk was concerned, in the space of between 6 months and a year...

It's pretty hard to beleive, but if you've got a year to spare and do some research, you can reach your peak without taking steroid type substances...

It is ONLY recommended to EVER take a steroid type substance, when you have actually genetically reached your peak, and want to bulk past the natural size that your body was meant to be..

If you want that, then steriods is the only way to get that extra size...

If your not at your genetic peak yet though, the only reason for taking things like this is to speed up the process... Generally want of speed = laziness... If your not satisfied with your results so far, you may need to look at your diet and training regime..
I know because i've completely considered it myself.. Fortunately or unfortunately, my already damaged beyond repair liver would not be able to handle any steroids..


2 websites I HIGHLY HIGHLY HIGHLY recommend for bulking are :
