Definitely stack it with some sort of Test Base. Test Prop is ideal if you are going 4 weeks, but 4-ad will certainly do the trick. Check out Primodial Performance's Dermacrine. Feedback (on here) says its about 150mg-200mg of Test. I wrote up a DBOL/1-ad cycle for this kid and he put on 31lbs (~60% was clean weight). HCG is an option too. Last resort, stack it with DHEA.
You are going to want to stack it a Test-Base for a host of reasons, without it, in about 2-3week you will have nearly 0 testosterone in your body. You will feel like total crap. Second, the gains are better... much better. I ran 1-ad/4-ad and gained ~20lbs on my first cycle. Sometime after that I ran 1-ad solo and gained only about 5-6lbs, although my strength was insane. I went from squatting 225x12 to 405x15 - we are talking full squats, ass to the floor. My bench didn't improve proportionally that much... but legs were my strength, and shoulders were not... this is about 7 years ago.
in short, if it's legit 1-ad... find a test base. I wouldn't hesitate to use Primodial's products, although I have only used the Toco-6 product. Maybe you could use 1.5x the dose, to get 250-300mg of test weekly and use HCG to put you at 300mg-400mg. It's not a lot of test, but it will make all the difference in the world in your results & how you feel.
