I don' t know how much you should be running. Thats up to you. Look at the half-lives of the compounds. Prop is like 2 days I believe and enanthate is 10.5 days. Its been noted it takes people 2 to even three weeks to notice enanthate effects. I would imagine prop would hit much sooner. So you could run the prop for two weeks with enanthate and then just pin enanthate after week 2. Or yo could wait until week three. I have never done this or know anyone that has.
Personally I wouldn't bother with it. Just complicating things. Prop would have to be pinned every day or every other day. Were you aware of that. Injections hurt. I don't mean as they happen but there can be significant border line debilitating muscle soreness after. In muscle that has never been injected with steroids it is worse. This is called PIP post injection pain. So you are gonna be pining this prop at a min of every other day. You are gonna end up having a bunch of injection sites on your body you are rotating between and also likely going to be pinning at sites that are probably still very tender and painful.
I first pinned my delts with Enanthate twice a week and the pain and swelling I had made me think I was having an allergic reaction or an infection. Also the pip from Prop is a lot worse. Come to think of it there is prop in sustanon which I have ran that is a blend of various esters and the pip was kinda painful and my muscles were no "virgin" as they say.
I am gonna just reiterate I think you should stick to enanthate. But if you don't want to then pin 50-100 mgs of the prop every other day for two or three weeks in conjunction with the enanthate at whatever dose you want. You will probably have a huge spike one week as they both kick in but it will settle a a few days after your last injection of prop.
PCT. Its standard to use a SERM, Selective estrogen receptor modulator. The two that people use either separately or in unison are tamoxifen and clomid. People also use HCG. HCG jumpstarts the testes the Lydig cells. The SERMS restart the pituitary. To produce LH and FSH gonadotropic hormones secreted by gonadotrpic cells in the anterior pituitary.
People usually wait a certain number of weeks after last pin to take into account half life. You see a lot of people running tamoxifin for four weeks at 40 40 20 20 or 40 20 20 20 thats in mgs and Clomid 100 50 50 50 or 50 50 50 50. People have done it a bund of different ways and I have yet to find out how these dosages came about. I personally took tamoxifen for four weeks at 40 40 20 20 and thats it and somehow recovered a bit. I personally would take a more aggressive approach.
Google the power pct by dr scally. That is an interesting read. I would utilize his approach next time I pct.
