Some of the approved drugs are synthetic versions of the natural hormones, such as trenbolone acetate and zeranol. Just like the natural hormone implants, before FDA approved these drugs, FDA required information and/or toxicological testing in laboratory animals to determine safe levels in the animal products that we eat (edible tissues). Furthermore, FDA required that the manufacturers demonstrate that the amount of hormone left in each edible tissue after treatment is below the appropriate safe level. As described above, a safe level is a level which would be expected to have no harmful effect in humans.
As you might have known by now that the bad effects of anabolic steroids cannot be paralleled by the growth hormone supplements. Where long term use of steroids can lead to male impotency and/or infections within genitals, growth hormone supplements have no such effects. Both HGH and steroid are used for muscular growth but after achieving the desired function, it’s really hard to quit using steroids. As far as HGH is concerned, it has no addictive properties because the growth hormone supplements are made from natural sources. So if you are taking HGH products, you don’t have the risk of filling your body with chemicals.
