Some bodybuilders and athletes use trenbolone for its muscle-building and otherwise performance-enhancing effects. [ citation needed ] Such use is illegal in the United States and many other countries. The DEA classifies trenbolone as a Schedule III controlled substance under the Controlled Substances Act .  Trenbolone is classified as a Schedule 4 drug in Canada  and a class C drug with no penalty for personal use or possession in the United Kingdom .  Use or possession of steroids without a prescription is a crime in Australia .  The infamous "duchess" cocktail administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , metenolone , and trenbolone. 
Of course, Parabolan can also be easily utilized for the purpose of fat loss, cutting, and pre-contest. It is in fact the most highly sought after anabolic steroid by competitive bodybuilders, and is considered such an indispensable addition in a competitive bodybuilder’s cycle that it is commonly referred to as “the nectar of the Gods”. Trenbolone’s extremely strong nutrient partitioning effects can result in fairly rapid fat loss when combined with a clean caloric deficit and proper training. Parabolan’s highly androgenic nature also tends to bring out the hardness and vascularity of the muscles and physique, creating the “3D” look commonly aspired by bodybuilders (provided that body fat is low enough to see this).
Regarding their quality has to be said that only Winstrol can be found in all three sources: Human grade pharmaceuticals, veterinarian grade and underground. When it comes to Tren or Equipoise you will have to choose between underground labs and veterinary grade pharmaceuticals. Since the quality of underground labs are quite low, a wiser decision would be to choose a vet grade Tren or Equipoise. For this, you will have to buy a bottle of Equipoise and another one of Fna-Palettes that would have to carefully convert into Trenbolone acetate. If you decide to go this way, than be very careful to sanitary conditions and strictly follow the right doses when mixing.
