LOLOLOL some 15-16 year old asked me to get him roids... I was like umm did you hit puberty yet??? Talk to me after you have.
I definitly have to agree, when you're a teen you will definitly mess something up. I think mainly emotionally. Teenagers have so much stress as it is, when you pump a ton of hormones into you it's a recipe for disaster at that age.
Here's what I think you ought to do. I don't care if you told them the risks Re-iterate them and tell them it will close off there growth plates prematurely and can make them bald and they can't drink alcohol while on them and in fact lie to them, who cares, you're saving there health tell them steroids will shut down there testosterone production forever and that they will grow breasts and whatever crazy shit you can think of. Warn them also, that they do random steroids test and they can get caught and kicked out of school and fine and go to jail or something too.
If that doesn't work go get empty capsules and take creatine and capsulate it and sell them the pills you made and tell them it is d-bol or something

. They will never know the difference they will gain like 8 pounds strength endurance will go up and then a placebo effect might even occur, where they will think there getting bigger and stronger. lol.
***I know people say about how in high school you have so much testosterone and it is like you are on roids, but that is a very bad analogy because yea you are at your peak or peaking probably test levels but we are talking like micro or nano gram amounts here, injecting roids your putting in pharmacological amounts of 100's of milligrams it makes a big difference in muscle growth and performance at any age.
