I think the pros that endorse a supplement should be off all drugs including HRT for a year. It would be interesting to see how they look in the supplement ad. The fact is that insecure young men are spending their hard earned money buying snake oil. The real supplement of the guys in the ads are drugs.
The real fact is that if steroids, GH, LH, insulin, thyroid, anti estrogen and all the rest of the junk were legal all bodybuilding supplements ads would go away. The ads would be pictures of bodybuilding pros holding a vial and a syringe. I can see the ad now. Our brand of testosterone is proven to be 84% more effective in clinical trials conducted in Bulgaria University than the leading brand.
