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.
Meanwhile, Clenbuterol is not actually a steroid. Rather, this is a substance that increase the amount of oxygen that can get around the body. In turn, this then increases the amount of fat being burned as well as enhancing energy in the gym. On top of this, Clenbuterol is also a mild stimulant, which increases the metabolism. Clenbuterol can be dangerous in the long term and may cause heart problems in particular. In small doses though, there is less to worry about and there is no chance of impaired testosterone production, impotence or other side effects associated with testosterone or steroids. It’s also relatively liver toxic.
