first,...lol. how old are u. you sound like your either 15 or a wrestler.
if your 15 your too young, sell it back. not that i should talk, i took my first cycle of 10 russian sus at 16, i was 150. now im 18...3 cycles later, and im 185 and quite lean.
but if yer gonna do it anyway, this is how...
1 250mg shot in the glute (yer ass bro) every 5th day. continue this for 8 weeks.
shoot it high on your glute,...so u can sit after it gets sore.
you should experience about 15-20lbs of gain if its yer first cycle, if you eat right ( lots of protein and carbs), and train hard, real hard. you must also continue to train after yer cycle, even if you dont really feel like it cuz you start losing a little weight.
you will experience a-lot of water gain, thats just how omnadren works. so when u start losing weight and strength, convince yerself its just water...this will help you to mentally still want to lift. you "will" look watery from this steroid,...dont mistake it for fat...unless it is, and you are really fat, but at 125lbs i couldnt imagine u are
u should keep anywhere from about 10-15lbs depending on how yer body responds.
u dont need anti estrogens, as 250mg a week is not high enuf dose to require them. although yer nuts will shrink,...dont be scared, they grow back...lol
also, if you are young, and shooting test, you will wake up with rock hard wood every mornig. you prolly have to beat off to get rid of it...lol
any more questions dont hesitate to ask, ill check up on you.
another very important thing,...research, research, and research

some more, cuz with steroids knowledge is power, as well as safety.
hope i can help
