I'm curious, is there anyone on here who knows from experience the effects of taking HGH, or some kind of anabolic steroid, and compared it to RPD? Despite it being synthetic, you'd still probably see better results from steroids than just RPD.
Yeah sure real great results; shrinking testikels, ruined kidness/liver, extreme agression, spontanious growth of tissue where it doesn't belong.
I have no personal experience with any of them and would avoid them like the plague. I think in general the results are over estimated and the side effects severely underestimated. Tons of people are taking steriods, some of them are genetic freaks that would have been huge, if they exercised heavy, anyway. There are however plenty of great physiques from the past when far fewer people exercised with weights and steroid and other such crap had yet to be invented. Bob Hoffman and Bill Pearl being only two of them. And then there are much older examples to be admired carved from stone by ancient sculptors. Thousands of years ago such man existed because otherwise those sculptors would not have known how to carve such statue, it not being possible to predict how a very large men would look like without having ever seen one. Muscular shapes change when they get bigger.
If you are considering taking any such synthetic aids consider the above. Train hard, very hard and you will get as big as your genetics allow for without destroying your body/mind in the process.
