Oxymetholone is without a doubt the strongest and most visibly active steroid to date. Not only does it act very rapidly, it causes a virtual explosion of mass. Gains of up to 10 pounds in 2 weeks are not uncommon. This is largely due to a moderate to low androgenic effect combined with a high anabolic activity also mediated by non-AR mechanisms (mechanisms other than simply binding the androgen receptor). You can imagine that the gains made on oxymetholone aren't the leanest. You would note a drastic smoothing out of the muscle due to estrogen-related fat (lipolysis) and water retention. This lipolysis has been shown to be rather drastic. One study1 on long-term hemodialysis patients showed beyond a doubt the role that oxymetholone can play in causing hyperlipedemia. The fat deposition rate, post-hepatic (after processing by the liver), increased drastically in the oxymetholone group while numbers remained stable in the control group.
When buying Anadrol from an underground lab, you could end up with a pharmaceutical standard tablet or you are likely to get a version of Anadrol that has been diluted or is not even Anadrol, so you need to try and find a lab that produces the real version, which can be a very hard task but they are out there. Also, if you are thinking of buying Anadrol online, you need to be very cautious in this area as well because there are a lot more fake Anadrol tablets online in comparison to the black market. It may not be a good idea to buy Anadrol from websites.
