Well you should probably read up on your own, and thats usually what i would tell you to do (There is a sticky in the "Cycle" section that explains most everything but i'm bored

so here you go :
S-Drol-typically ran for 3 weeks, at dosages ranging from 10mg/day to 20mg/day (30 for advanced). Expect results with at 10/20/20 type cycle should include 10-15lbs dry mass, you should be able to keep almost all of this during and after PCT. Sides include (for me at least) Back Pumps, Backne, Lethargy, Iritability, Some say sex drive suffers, but for me it increased astronomicaly, Obviously a pretty heavy "shut-down" of natural test production.
Phera-Ran 3-4 weeks. Typically dosages range from 15-45mg/day. Most users put on around 10-15lbs with this compound also. The difference between s-drol and phera is that where s-drol is considered very dry, phera is not. In fact it will put a decent amount of water and a little fat on you. Obviously water will not stay during PCT and after, therefore you can expect to lose a few pounds during PCT and after, this is the reason why people will run a phera->S-drol bridge. Sides are similar to s-drol although it seems more users experience estrogenic/progest sides than with s-drol, it is also thought that phera is slightly less harsh.
Epistane-This is what i would recommend to you for your first cycle(although i did s-drol for my first). This compound is usually ran from 4-6 weeks, at varying dosages (20-60mg/day)
Epistane is considered to be anti-estrogenic to a degree and therefore you can expect your gains to be quite dry, and the incidence of estrog. related sides (ie:gyno) to be lower. Gains on a 4-6 week cycle would be in the neighborhood of 10lbs maybe more for some. This is with a cycle length up to twice as long as s-drol for around the same gains, but it seems to be considerably gentler on the body(a good PCT is still in order though). Sides for a modestly dosed cycle should be minimal.
Hopes this helps.....................(Now rep me)....Just Kidding!
