Initially, Trenbolone was an oral veterinary drug for improving the muscle gains in cattle. It first came into existence during the mid-60s through a German Company, Hoechst-Roussel. The manufacturers branded their veterinary product, Finajet. At the same time, Trenbolone enanthate powder was a subject of research in Los Angeles at the University of California.
This Tren Ace Germany production gained popularity for a while until its discontinuation in the late 80s. A couple of years later, another manufacturing plant in France came up with human-grade trenbolone hexahydrobenzylcarbonate (Parabolan) under the brand name, Negma. Unfortunately, this too was illegalized in 1997.
Finally, Trenbolone enanthate appeared in the limelight as an independent product in 2004 with a brand label, trenabol. The British Dragon Company manufactured the steroid as an underground lab product. Although the corporation went out of business in 2006, the brand is still available in the black market.
Whereas Tren A doubles as a pharma and vet grade drug, Tren E and Parabolan are strictly for human use.
