Anywhere from 150 to 500 mg is perfectly good. Don't forget you're going to get shut down no matter what so you might as well push the dosage a little bit.
You can get super strong on tren. You can bulk on it. You can cut on it. It really does it all. I've seen some amazing transformations. I would recommend 250 mg a week.
Make sure with testosterone you're getting really good quality. I see a lot of underdosed testosterone floating around right now so you got to be careful.
