I want to start off by saying before I saw all the reviews I did end up buying my Sustanon 250 from steroid warehouse. I just hope the potency is correct. It took 2 weeks to show up so no issues there, then I had to test it seeing all the bad reviews, so I bought a test kit, and it shows it is Sustanon 250. No idea if the potency is correct, but I'll find out soon. I am new to this so I have been trying to figure out the dosage. Sustanon 250 is supposed to be 250mg/ml. I suppose I'll start there and see how that goes. I want 250mg of testosterone so by those numbers I'll need to inject 1cc, or 1ml of sustanon 250. Now it supposed to last 2-3 weeks. How often should I inject? I'm thinking every 2 weeks. Is that too soon should I wait 3 weeks before I inject another 1ml? Also should I cycle 8weeks or 12 weeks?
