If you are about to take anabolic steroids for enhancing your body performance and building up muscle mass then you should be concerned about the sources your dose comes from. Due to the sharp increase, over the last few years, in the number of Americans taking steroids – around 6 million people, but unofficially the number could be higher – numerous unlogged steroid providers have invaded the market.

There are mainly three classes of steroids that are currently available: Human grade, underground grade, and the third being veterinary steroids produced in Europe (most of them). Human grade steroids are designed for treating different human diseases. Pharmaceutical companies that meet a set of national and international standards manufacture them.

Human grade steroids are produced in a sterile environment, and are consistently dosed. Contrary to this, underground grade steroids are at a high risk of being contaminated with different bacteria, can be under dosed and are produced in poor sanitary conditions. As a consequence, the price is much lower than in the case of Human grade steroids.

Veterinary steroids are good ones because they are produced in sterile conditions, following quality measures in the place of their production. But even then, we cannot talk about the same level of control in their case as in case of Human grade steroids. The same thing can be said about ingredients and doses, but one can say for sure that they are better monitored than underground grade steroids, where no control is taken.

Most popular veterinary steroids used in humans:

  • Trenbolone

By far, Trenbolone is one of the most powerful steroids, and has proved its superiority over time. It is a horse steroid that is largely used in humans, having three times stronger characteristics than Testosterone. There are other forms of Trenbolone, but only Trenbolone-acetate is known to be produced in veterinary steroids labs.

  • Equipoise

Equipoise, or officially named Boldenone Undecylenate, is another veterinarian steroid that had been initially used in horses. It provides lean muscle mass and strength, but at a slower rate.

  • Winstrol

Winstrol (Stanozolol) is the third most used horse steroid by bodybuilders. The version developed by veterinary labs is known as Winny-V. It is largely used during cutting cycles, as it effectively burns fat and produces nice lean muscle mass gains.


As you see, veterinary steroids are those designed for animal use (especially in horses), but are largely used in humans too. These steroids cannot be found in human grade pharmaceuticals, but are produced in underground labs.
