I have seen "sustanon" come in many different dosages and compound combinations. I have seen as high as 450mg/ml where the original sustanon was 250mg/ml. I have seen it with the original 4 compounds which was test p, test pp, test isocap, test deca. I have seen a variation of it where the test isocap is replaced with a test base. Then I have seen test p, test c, test e put together to be called sust and also variations where it has test deca. Really just about everything someone wants to throw together and call sust, just because the name sustanon is very popular amongst newcomers that they see a few different compounds and the name sust and they buy it up cause they don't know what sustanon is really.
I have read a lot of different ways to take it. I took it as my very first cycle along with dbol and I put on a good 30lbs. I shot it twice a week and took the dbol at 50mg ed. The sustanon I had was the Russian amps that said cytohoh 250mg on them. They were real good, before the Pakistan and Mexican ones. These were blue writing on the amp in Russian, the Pakistan was yellow(carachi) and the Mexican was green. I haven't seen the Russian ones since I had them back in 1999.
I see articles where people say take it twice a week, three times a week, every day for 3 weeks, and once a week in high dose. I can understand the theory behind them but for me twice a week worked good and that's all I ever did of it. I guess everything is theory till you actually do it and see for yourself and see what works for you cause it might be different than what worked for someone else.
