much less risk of side effects, so instead of side effect gains you just get no gains.
I don't mean to be a cunt but based on what you have said here you would be best to forget about using steroids for the time being. They will only do you harm at the moment.
You are quite young and i would only be for AAS use at your age for individuals that are far beyond the average gym specimen.
that said its your body - If you deiced to do it please make sure you have a proper plan including adex and HCG during your cycle and Nolvadex OR Clomid for your PCT.
If you are not familiar with these drugs then that should be a massive warning sign to you and as i said you will hurt yourself and are not ready for AAS.
