I kiked started my cycle with prop. 100mg eod. Along with test e. The first month i didnt gain any waterwieght i just got stronger. I thought the prop kikstart would at least give a few lbs of water with stregnth, but it didnt. The reason is cause the test e i was taking 750mg a week was not in effect the first 4 weeks. The prop was the only thing kikin in the first 4 weeks. So if ya do the math, I was only takin in about 350mg a week of prop. which is hardly enough to put weight on. I did get stonger though. So if you were goin to do prop only. I would say at least 150mg eod, to get some good gains, but 4-6 weeks. Extend the cycle to at least 10 weeks.
