For what man? You dont need test boosters for them to get a better edge they are teenagers for god sake....If they are lifting right, and training right, then they dont need that extra edge. No parent in their right mind would put their teenage sons on Roids, and it looks like you have that down, which is great, but there are some serious side effects from testosterone boosters. Find a testosterone supplement you want to use, google it and look at all the side effects it can cause. I mean shit, DHEA, which you can buy at a vitamin store, can cause Testicular shrinkage, acne, hairloss, increased estrogen, cancer, all kinds of great stuff. If you were asking about 30 year old men, yeah sure go for it, but these are kids man...friggin kids. Call your doctor and ask him or her about putting your teenage boys on testosterone boosters, and see what they say. Its your children though.....do what you like.
