Last 4-6 weeks. Nothing is harder on lipids so it has to be for a short time and well thought out. 12 weeks on prop, I would shorten to 10, up the dose and you will more than likely do a lot better. 300mgs is only about 260mg/wk, it is something but not too much. That is why you didn't see so much right away. If you ran it at say 1.5ml EOD, that would be something for sure and ideally if you don't mind pinning, I would roll 50-75mgs per day. It just depends, some don't need that much, I do well with more it seems and prop and I get along great. Anyways, winny, 50mg is about half of what many take but it may allow you to run it 6 weeks. Cissus, extra fish oil will help those joints and you more than likely can lower your AI dose some as well, I do about half of it. You are running test, unless you are dieting hard you will lose weight and remember fat loss is dependent on the test doseage, more tends to lead to more fat loss especially with a good diet and cardio, actually it just amplifies their effects as lipolysis goes through the roof.
