I don't understand how being 6'0, 200 pounds, at 15% body fat is not a good base? I think that is pretty solid. I would recommend cutting down your body fat percentage a tad bit before starting your cycle. This will make your goals more obtainable.
You will want to run an AI with dbol, because it can convert to estrogen very easily. Not doing so could put you a risk for gyno and more than tolerable edema real quick. Arimidex is a good option at .5 mg eod, but like Dylan suggested, I would use aromasin 12.5 mg eod, and maybe even every day while on the dbol. And since it is oral, 4 weeks is all you need to run it. Make sure you take precaution and protect your liver because D-Bol can be quite toxic. After the D-Bol, if you keep your test dose at 1 cc per week, 250-300 mg, then you may not need an AI, but would still have it ready just in case. People use HCG in different ways.. I have found it from my experience to use it for a short period, starting a few weeks before PCT. I run 250 iu, twice per week for two weeks. Then I bump the dose to 500 iu, twice per for the last 2 weeks.
Make sure you have proper cycle support for your liver, lipids, and testicular atrophy. Making sure you cover those basis will make your cycle more effective, as well as making it easier to ensure a full recovery. You should run N2Guard the entire cycle. It is by far the best cycle support supplement out there. It will help with your liver, blood pressure, as well as other things. I would also suggest running another liver support while on the dbol. Liv-52 is a great option. The HCG is going to help with your testicular atrophy right before PCT, but you can also help it by taking a natural test booster while on cycle. HCGenerate is designed specifically for this reason, and you won't be able to find a better product out there for this purpose. I personally start it the first day of the cycle. It is wise to start it as soon as you notice a change of size in your balls.
Now if you want to keep your gains, unlike your buddy.. you need to run a full and thorough PCT. There are a lot of threads on this website that explain a "new" way of doing things. Clomid is an excellent base SERM, but you will want to add an AI to this. Armidex or Aromasin would suffice... but the best AI for PCT is Forma Stanzol. Forma Stanzol is a transdermal version of the AI formestane. If you don't know much about formestane.. look it up. Forma will help at stopping the conversion of test to estrogen like an AI, and will block it like a SERM. It also will help elevated natural test levels, and IGF-1. All of these characteristics are what needs to be done in PCT, and that is why Forma is perfect for it. You can purchase this at mrsupps.com After your Base of Clomid and Forma.. you will want to add in a natural test boosting product or two. I have personally used the Unleashed and Post Cycle combo from needtobuildmuscle.com. Unleashed will help elevate test as well as make the test more usable. Post Cycle will also help elevate test, as well as aid in cleansing your body and liver. D-AA is also a great natural test booster. You can go with other natural test booster.. but these products are specifically designed for this reason. They are of the highest quality. I would recommend them over any over hyped, over priced product GNC has. Do this for PCT, as well as HCGenerate and HCG on cycle and I guarantee you not have a problem recovering and keeping the majority of your gains.
To sum things up, I would set up your cycle, support, and PCT this way:
Cycle:
1-10 Test E 250 mg/week
1-4 D-Bol 20-40 mg/day
1-12 Aromasin 12.5 mg eod, ed while on D-Bol
1-12 HCGenerate
1-12 N2Guard
1-6 Liv-52
PCT:
9-10 HCG 250 iu, twice per week
11-12 HCG 500 iu, twice per week
13-16 Clomid 25 mg/ed
13-18 Forma Stanzol, 5 pumps twice per day
13-16 Unleashed/Post Cycle Combo
13-16 D-AA 3 g/ed
It took about 20 minutes of my life to type and explain this as thoroughly as possible, so I hope you appreciated it.
