LOL, you're comparing the effects of Anadrol to Creatine ?!!?... please tell me this is a joke...
Anadrol is hands down the strongest oral (if not altogether!) steroid made in the world. That's all there is to say about it. Next you'll be telling us dbol is about as effective as some good amino acids 
No I'm not joking in the slightest. I don't think you read my post very carefully. Here's the thing, and think about it before you dismiss it: steroids can cause quick weight gain without being very (comparatively) androgenic. The converse is also true (think Halo, mibolerone, even tren. Which do you think is more androgenic, drol or tren?). Corticosteroids cause severe water retention too, and in fact one mechanism through which anabolic steroids can cause water retention is through mineral-corticoid receptor interaction. MuscleMcMannus touched on this. The comparison to creatine was to show that a quick weight gain, and even strength gain, doesn't necessarily mean its extremely androgenic since there are other pathways at work.
I did not say Anadrol isn't effective or "weak", just that it doesn't seem very androgenic to
me i.e. doesn't cause zits, boost or depress sex drive dramatically, doesn't stimulate the CNS. And etc., etc. Anadrol is also known to be an extremely weak binder of the AR (it's possible its metabolites are though). My hunch is that on a
mg to mg basis Anadrol might be a weaker androgen than something like Winstrol even. If anyone knows of females who have run low dosages of Anadrol please chime in; did they get lots of virilization? I remember Duchaine saying females running 25mg/day didn't get lots of virilization.
