I am 18 years old, 5 8 and weigh 155 lbs. I took a prohormone, which i am aware is stupid. its two compounds are 4-chloro-17a-methyl-androst-1, 4-dien3-17b-diol (superdrol) -15mg and 2a,17a dimethyl-etiocholan-3-one, 17b-ol (halodrol) -25mg. My post cycle therapy is tamoxifen citrate (nolvadex)- 20mg. My question is, is there any chance of me developing gynecomastia from this? and since the nolva is 20mg, is it okay to take one pill a day?
