Yup they prohormones used to be found in Animal test until that was banned...
And difference can be writen in a long documentation but main difference is the conversion, eg: steroids are allready in their converted compound, where as prohormones are not.
To try make more clear of what i'm trying to say here is a snippted of some information

A steroid, or more correctly and anabolic steroid, is an exogenous hormone.
Use of an anabolic steroid increases ones hormone levels to supra-physiological levels (i.e. levels one could not achieve naturally).
Most steroids are inactive when taken orally, thus they are injected. A few are altered (like dianabol) to make them active orally. One such method is my methylating the steroid. The methylation cause the steroid to pass through the liver mostly unharmed. This, however, makes it quite taxing on the liver.
As well, most oral steroids are not very anabolic (muscle building) and so any experience steroid expert will tell you that a "cycle" should never only include orals (i.e. you could stack orals with injectibles).
A "pro-hormone" is something that is not an active hormone (like a steroid) but it is a precursor to a steroid. In other words, there are enzymes in your body that can convert the PH into an active hormone (steroid).
For example, 4-androstendiol will convert to testosterone (via an enzyme in the body).
1, 4 androstendiol will convert to boldenone (a steroid).
1 androstendiol (1-AD) will convert to 1-testosterone.
Interstingly 1-testosterone is an actual steroid, but a legal one (there are many OTC supps that incorporate it). It is often referred to as a pro-steroid, because (for now) it is a legal supplement.
So, PHs (and PSs) in order to qualify as a "dietary supplement" must be taken orally (pursuant to the DSHEA). So you again are back to the issue of how potent this PH/PS will be, since it is not very "bioavailable".
People estimate that the PH/PSs are anywhere from 5-40% bioavailable. Some individuals have injected these (illegally) in which case you'd see results similar to various illegal anabolic compounds.
But orally, they will ultimately provide some exogenous hormones (and this you see many people claiming terrific results) just not as much as anything delivered via injection.
So, the biggest difference between PHs (and especially PSs) and illegal anabolic compounds is the delivery mechanism.
Now, recently we are seeing chemists methlylating some of these PHs and PSs. Methyl 1-Test is very big right now. It is highly orally active and rivals any "true" steroid. Its also pretty harsh on the liver.
And so with M1T, we are seeing some outrageous growth.
And other companies are starting to Methylate other PHs and PSs.
Many experts believe that once one of these (currently) legal compounds are methylated, they become illegal. So this is very much a grey area.
