IMO, Steveo's post is a fair, unbiased, and accurate assesment of you situation. Anabolic steroids bombard your body with sythetic hormones that are MORE anabolic than testosterone. Testosterone is anabolic, and quite noticable when raised SIGNIFICANTLY, but the raise in test an 18 y/o is going to experience from a test booster is likely too small to create any measurable anabolic gain, at least one measurable enough to warrant spending money and toying with your hormones. Likely greater results could be seen from simpler supplements and diet changes.
I'm not saying boosters cant raise test in young people, just that it's a matter of relavance.
Example: (and these are just random numbers to demonstrate a point)
45 y/o old man with test level 300
18 y/o man with test level 800
Test booster raises test 150.
45 y/o man = 50% increase
18 y/o man = 18% increase
Obviously this is going to make a bigger difference to the older male.
Younger people with high estrogen, or low test, may see different benefits from AI's and test boosters, but I think the experience is generally more valuable in older men.
As far as steroids/PH, they are quite normalized in the internet world and among bodybuilders, but they are serious sh*t. Doing one cycle makes no sense, because nobody's going to be willing to face the risks to do one cycle, and then just go back to natural after it's over. Doesn't happen. And the risks are REAL. Some people do everything right and still get screwed up, regardless of age and experience.
