So just because some people look as though they have only 3% body fat does not automatically mean they are loaded on PEDs. It could mean they have found something that works for them and makes them extremely efficient at using the hormones produced in their own bodies. And there is even more going on to getting strong than what I mentioned here in this article. We didn’t take into account diet, supplementation , or health history. There is a lot going on biologically when it comes to cell growth than what we can see from the outside.
In the United States, supplements such as tetrahydrogestrinone (THG) and androstenedione (street name "Andro") previously could be purchased legally without a prescription through many commercial sources, including health food stores. Steroidal supplements can be converted into testosterone or a similar compound in the body. Less is known about the side effects of steroidal supplements, but if large quantities of these compounds substantially increase testosterone levels in the body, then they also are likely to produce the same side effects as anabolic steroids themselves. The purchase of these supplements, with the notable exception of dehydroepiandrosterone (DHEA), became illegal after the passage in 2004 of amendments to the Controlled Substances Act.
