No matter what you take, you are going to effect your natural production. The less you take, and the shorter the period "on", the easier it will be to recover. This cycle is certainly on the moderate side. In fact, you are close to the minimal amount of gear I would suggest to still be worth the effort. I would suggest using a long acting test for your first run because the pain from prop can be bad to the point that you might not be able to train an injected body part for several days. After you have more experience with gear, consider prop but for now, I would use a low dose of test e. With the right amount of AI, you can avoid too much water retention. Test e may still be quite painful considering that you have never injected oil based steroids before, but it will be a lot easier to deal with than prop. Plus, you will only need 1-2 shots a wk, vs EOD, which would require experience with injecting many different sites. With test e, dosed at 1cc EW about 250mg, you will be able to use just glutes, or glutes and quads for your rotation.
You want to run HCG during cycle, not in PCT. It will keep you from letting your body naturally produce so you would not really be able to recover if you use it during PCT. Also, I am extending the plan by a couple wks. If you want to get really ripped, you will have to start dieting before you start your gear and then time it up so that you are finished cutting by the end of the cycle. It takes longer than 8 wks to get in super lean, especially if you are at 15%.
Also, as long as you use an AI, there is no need to use nolvadex on cycle. Your AI will stop too much estrogen from forming and if you have an issue, you can increase the dose. Nolvadex would stop estrogen from attaching to the receptor. Since you wont have additional estrogen floating around, there is no need to bind up the receptors. Here is how I would run your plan. You said that you have your diet on point. so rest assured, if your diet is on point, you can get contest lean! I have used similar cyckles with men's physique athletes, You can use whichever AI you want to use but I am most comfortable with adex so I am writing this plan with it.
