Presently, there are three types or grades of steroids in the market. Human Grade, Underground Grade, and Veterinary or Animal Steroids.

Human Grade steroids are used to treat different human diseases and meet the national and international standards of manufacturing and derivation and are made by top Pharma companies. They are manufactured under a sterile environment and promise to deliver pure and original medicine.

Underground grade steroids, on the other hand, have a high risk of contamination and that is why cost cheaper than Human Grade Steroids. These drugs are manufactured by unlicensed companies, who operate illegally and sell their stuff in the black market only. These are mainly available with your local supplement dealer, who can only give you a personal assurance, but never anything on paper.

Veterinary steroids are also called Horse Steroids but they are not just used in horses but also in other animals. These steroids are also very famous among bodybuilders and other athletes due to high anabolic properties and low side-effects. These steroids are also said to quickly assimilate into the body and are out of the system faster than other types of steroids. The manufacturing of these steroids is in comparison with the Human Grade steroids. The three most common animal steroids used in humans are Equipose, Trenbolone, and Winstrol.

Some people have this doubt that Veterinary steroids do not work on humans because they are made for animals. This is not at all true. Equipoise is Equipoise, whether it is used by animals or humans. Just because the label says that it is for animal use doesn’t make it any less effective for humans. Your receptors will accept animal steroids as good as Human Grade steroids.

The use of medications made for animals is commonly being used in humans for a long time. But please understand that it is illegal for veterinarians to sell any medication that is intended for animal use, to humans. Most packages clearly mention “Not Meant for Human Consumption”. However, in a lot of cases, medicines are common, with different names, used for the treatment of common illnesses. Many, and perhaps most, antibiotics are approved for use in humans and animals.

According to an April 2011 story by Brian Palmer in, many animal drugs are actually manufactured as human medications, because there is far more money invested in human drug research. In such cases, manufacturers sometimes reformulate their drugs for sale to animal owners. In other cases, large companies working in both the medical and veterinary fields develop the two formulations side by side. Just like ordinary medicines, veterinary drugs have to clear randomized, blinded, placebo-controlled trials.

Most of the animal grade steroids are not found in Human Grade steroids, but openly available in the Underground Grade steroids.

As per the FDA’s official website, it has been approving the use of a number of steroids and hormones for use on animals which includes estrogen, progesterone, testosterone, trenbolone, growth hormones, etc. since the 1950s. These drugs according to FDA increase the growth rates of animals and efficiency by which they convert the feed they eat into the meat.

Also, according to FDA, these drugs are approved only after information and studies which show that the food from the treated animals is safe for people to eat and that the drugs do not harm the treated animals or the environment. These steroid hormones are typically formulated as pellets or implants that are placed under the skin on the backside of the animal’s ear. The implants dissolve slowly under the skin and do not require removal. The ears of the treated animals are discarded and not used for human food.

When it comes to the dosages used by animals and humans the athletes, especially the bodybuilders have derived their own simple system of calculating the dosages of steroids to be used by humans as compared to the same salt being used by animals.

Say, for example, the dosage recommended for a horse for a particular steroid, hormone or peptide is 10mg/week and the average weight of the horse is 1000lbs, then by a simple calculation which is being used wrongly the dosage for a 200lb bodybuilder would be 2mg/week.

However, it is not that simple and as per the FDA guidelines to calculate the HED (Human Equivalent Dose), the formula used is:
Human dose (mg/kg) = animal dose (mg/kg) × (Animal weight in kgs/Human weight in kgs)

To check the science behind the calculations, check the FDA website and check the Guidance for Industry document openly available on the net.
