You have some specialized needs you should educate yourself on. I don't know what the current protocols are for testing Division 1, but you should know how you could be tested. To avoid detection you want to use short esters and short acting orals in combination for maximum short term affect. Short cycles require even stricter adherence to diet and training. You don't want to kill yourself in the weight room and fuck up soft tissue tendons from pushing too hard. Although with your background, i doubt that is much of a risk unless you just do something stupid. A good cycle is more about packing on mass and strength in the gym than just trying to hit a new PR every day.
Esters, which you should learn about are how long the active life is of the substance you are using. I think test propionate with a 4-6 week cycle with a dianabol kick for the first two weeks would work well for you. Test P is a bit harder to source than Test E or C, but shouldn't be too difficult. If you start sourcing now, you have plenty of time to get everything together before your planned cycle.
Educate yourself on AIs, anti-estrogens, and PCT. All will be crucial to achieving maximum results. The stickies in this forum are a good place to start then. Google "Bill Roberts steroids" and read up on everything he has to say.
You could easily add 10+ pounds of solid muscle on this type of cycle. It sounds like you are close, now just need the extra edge the others have.
There are those that might be morally opposed to athletes using PEDs. I appreciate the fantasy land they inhabit.
Editing. Also, use a liver protector like TUDCA while running an oral.
For amounts to use, 100mg injected every day of Test P and 40-60mg dbol for the first two weeks. You will likely retain a bunch of water with the dbol if you don't use an AI and even if you do you will retain some. Don't get too excited over a 10 pound gain the first two weeks as it is most water. What I see a lot of people crow about is 10 POUND GAIN in two weeks and then 2 weeks later crying about not gaining any more weight. It is just your body smoothing out the gains. Consume 1+ grams of protein per pound of bodyweight and aim for a modest calorie surplus overall (500 or so). Also, stay the fuck away from sweets and simple carbs.
