Results wise, users should expect extreme strength increases and weight gain in a relatively short 2-4 week period. Weight gain upwards of 20lbs in 4 weeks is not unheard of with this incredibly potent compound. Although subcutaneous water gain would be minimal, intramuscular water retention should be expected. This is due to inhibition of 11b-hydroxylase and build-up of mineralcorticoids which encourage salt and water retention within the muscles. The most obvious physical effects will be improved vascularity, aggressive muscular pumps, and oily skin.
While methyldrostanolone can stack well with most other steroids, it should never be stacked with another methylated (17aa) steroid.
In the case of low-dose use however, I do think it is a correct conclusion that for most, low dose Anavar use is more effective for cutting than equal dosages of most other anabolic steroids . This may be partly or entirely from additive effect with natural testosterone: such oxandrolone use may not suppress such its production, the user may enjoy both the full effect of his natural testosterone and the effect of the oxandrolone. In contrast, low-dose testosterone or nandrolone use results in substantial suppression of natural testosterone, and so there is less total effect.
