I am taking a mix now of TT Test Enanthate 200, Cyp 200, and Prop 100. 1/2 ml of each, once per week. To say that the Prop is working well would be guessing, since the others I mentioned are also in the mix, so it would be hard to pinpoint which was hitting the receptors the hardest. I will say this though, I LOVE those 3 together!!! NO PAIN, solid as a rock(as long as Nolvadex is added), and horny as an high-schooler to boot! I like it.
