clenbuterol,steroids,clenThe Trenbolone hormone is commonly classified as a veterinarian grade anabolic steroid. Trenbolone Acetate, although the most popular Tren compound among performance athletes is also essential to the livestock market. However, Trenbolone Enanthate does not fall into this category, not technically. Trenbolone Enanthate is strictly an underground black market anabolic steroid. The compound first appeared in 2004 under the British Dragon label Trenabol. This makes Trenbolone Enanthate the youngest of the three common Tren forms and the only one that has never been used in what we’d consider legitimate medicine. Trenbolone Acetate was actually studied in a human therapeutic capacity, however, largely rested on vet grounds. Then we have Parabolan, which is the only human grade or pharmacy grade Trenbolone hormone ever created and it enjoyed enormous success until its discontinuation in 1997.
