Test 600 has no official certifications. The product itself is not formally backed by any outside research, although its active ingredients do have an amount of proven research behind them. Most of these ingredients are already well known and proven on the market, so there is unlikely to be much change in their certification or research status in the near future. The FDA does not usually put intensive study or certification efforts into herbal extracts. Its safety and effectiveness are primarily a matter of looking at the broader research as discussed above for each ingredient.
Unlike many anabolics, Test-600x has no side effects. However, if you take the illegal version of this supplement, you may suffer from a battery of side effects. Unlike many anabolics, the illegal form of this supplement is not toxic to the liver or kidneys. However, it still can cause some serious side effects. One of these is gynecomastia, which is the development of secondary female characteristics, especially breast tissue. This happens in illegal forms of this supplement because pure injected testosterone can be converted to estrogen by the body. Gynecomastia is often very embarrassing, and you can avoid it by taking Test-600x instead of its illegal counterparts.
