First off, I'm glad that things we well with the wife. Thats really great news! Now just make sure you stay responsible with your gear use and dont make her regret it haha. The cycle looks fine. They've done a good job putting predesinged cycles together. The only thing i would change is the amount of adex. .5mg ED is high, especailly for that dose of test and considering your goal is muscle gain, not cutting. I wouldn't think you'd want anymore than .5mg EOD while on the dbol and maybe even slightly less when the dbol is over. I would split your test injections into 2x wk, like mon and thurs. This will keep things a little more stable. speaking of dosing, I would split your daily dbol dose into 2-3x per day, as the half life is quite short. Then when it's all said and done, PCT will start 2 wks after your last test shot. My only concern with your PCT program is the HCG. It looks like you are running it while in PCT. I would instead run the HCG through your cycle at 250iu 2x wk and finish up no closer than 3 days before PCT.
The ideal amount of time to wait before you run another cycle, is the amount of time it takes to reset your body, letting your liver, kidney and test levels return to normal. As for your natural test, you are on the lower end, but you don't have low test as far as medicine is concerned. I believe 300ng/dl is the low end of "normal". You're just about right there. With where you're at, I wouldn't be shocked if you have a hard time getting back to normal, after you run a cycle of 2. If you're interested in HRT, you can keep your levels at more like 1000ng/dl,
