Analysis: P-Plex
A couple of weeks ago we wrote about a Japanese analysis of the designer supplement Epistane. In the same article the researchers mentioned an analysis of another supplement, of which the active ingredient is an anabolic steroid: P-Plex, produced by Competitive Edge Labs. According to the Japanese, P-Plex does indeed contain madol. And something else too.
Madol is a pretty convincing steroid. According to Vida's Androgens and Anabolic Agents (1969), to start with it has a great androgenic:anabolic ratio.
VP = effect on the prostate; SV = effect on the sperm vesicles; LA = effect on the sphincter muscle. VP and SV are markers for masculinising side effects; LA is a marker for the desired muscle building effect. The values are compared with methyl testosterone, which is adjusted to 100.
According to recent German research, Madol is not carcinogenic. [Toxicol Lett. 2008 Dec 15;183(1-3):58-64.] In animal tests it has been shown to enlarge the heart muscle, however. The animals don’t become ill, but it is a matter of concern. When steroids enlarge the heart of human athletes, it's usually not a good sign.
The Japanese analysed the pills in a pot of P-Plex, batch number 080107. They did indeed contain madol – and its delta-4 metabolite. The figure below shows the big madol Peak-3, and the small Peak-4 from the metabolite.
The height of Peak-4 would suggest that the contamination is not much. The researchers suggest that it is released during the production process.
