Time is always the biggest limiting factor in a cycle. Your body will only gain as much muscle as it's willing to gain in a given period, no matter how much food and drugs you throw at it. Believe me, I've tried and so have many others, to add crazy amounts in short times. It never goes well. Still, nothing wrong with giving your body an optimal environment (insert evil mad scientist laugh here)! 

Ok, so you do have an issue here with your compounds. All of them are great for your goal, since they are all fast acting. The only thing better than prop would be TNE, as it will be working 100% from day one. The issue is that your Drol and OT are both very very liver toxic. I would highly suggest not running them together. Either one is going to raise your liver values so high that your Dr is going to faint if he sees your labs in a month. Seeing that your goal is adding muscle, I am going to opt for the Drol. I'd also add in some adex or other AI as needed. But keep it at the minimum to get the most out of this 4 wks

Real simple, cut and dry...

1-4

Test Prop dosed as you are normally used to dosing it, so that might be 100mg EOD or ED, depending on your level of experience 

Drol 50mg ED, split into 2 daily doses

The key is going to come down to how you eat. I'm assuming you are going to ramp the food, HARDCORE. Just be safe in all aspects. Drugs, food, supps, and training. There is always another period of time to grow, so don't try to squeeze in too much in 4 wks and hurt yourself in some way. Always keep in mind that time is your limiting factor and there is no getting around that. 

Best of luck. Do me a favor and come back to the QA and report in with how you do! I will reply, so that everyone reading can hear about your 4 week blast results.
