Listen, if you are taking or have taken Epivol, you are using an Anabolic/Androgenic/Steroid. In fact it is very similar to Winstrol in effect. All steroids are derivatives of Testosterone. Testosterone is the primary sex hormone that makes men muscular compared to women. Testosterone is the standard by which all AAS are measured. In the 1950's, pharmaceutical companies were able to modify the Testosterone structure and create multiple derivatives of Testosterone that had distinct variations in the way it acted in the body. They created literally hundreds of modified hormones and developed the best ones for sale to treat a variety of disorders. Some AAS are more Anabolic than Test, but less Androgenic. Some are more Androgenic and less Anabolic. In laymans terms, anabolic properties SEEM to be more important than Androgenic properties, so steroids like Anavar or Winstrol would appear to build more muscle than Test with less side effects. But theory and real world do not always line up. Therefor, the most potent steroids tend to also have nasty side effects (ex. Trenbolone). As it turns out, mother nature (or God) knew best and "test is best". While devoloping all of these derivative variations of Testosterone, many were left "on the table" and never devoloped or patented for sale. Around 1997, some chemists realized that there might be a loophole in the law since they could "re-develope" the old steroids that were never patented or comercially sold and instead market them as "supplements". It began with basic "pro-hormones", but ultimately led to actual "designer" steroids (including Epivol type steroids). Today we have access to a wide assortment of "over the counter" steroids that are just as effective (and toxic) as any other illegal steroids. This is a double-edged sword. Good for the knowledgeable, advanced lifter, but very confusing and potentially dangerous to someone in your position. That is why the FDA is poised to ban a whole bunch of these and ultimately entrench their agency further up our asses and in our biz!!! So I hope this helps, cause I had to get that off my chest! Lol... : )
