Methyldrostanolone, also known as Superdrol, methasteron and methyldrostanolone is a potent oral anabolic steroid. In structure, this steroid is a close derivative of drostanolone (Masteron). The only difference in this case is the addition of a c-17 alpha methyl group, a modification that gives this steroid high oral bioavailability. The two agents remain very comparable, however. Both methyldrostanolone and drostanolone are non-aromatizable, so there is no difference in the estrogenicity of these two steroids, and both steroids retain favorable anabolic to androgenic ratios. Lab assays do put Superdrol ahead, however, showing it to possess 4 times the anabolic potency of oral methyltestosterone while displaying only 20% of the androgenicity (a 20:1 ratio, compared to 3:1). Methyldrostanolone is favored by athletes for its moderate anabolic properties, which are usually accompanied by fat loss and minimal androgenic side effects.
Giovanni... I am sorry - I have looked but never found a similar solution for Photoshop CS3 and earlier. I've been wanting a filter like this for years and some time ago traced some information about one that is an add in for Gimp (I think) but so far as making this in Photoshop without Pixel Bender I think you're probably out of luck in finding a simple solution. However you can get a spiral effect by repeatedly copying, sizing and rotating a single layer in Photoshop provided you do this around a central point. I'll put an explanation of this on my "to do list" for you and try to blog it soonish.
