You should try tren solo sometime. It can really be beneficial. I think that the most you should ever run tren is 400 mg a week. I would not go higher.
I love testosterone. I think if you're doing TRT, you should do it at around 125 mg a week. If you're doing a cycle, you can go ahead and blast it up to 500 mg a week. If you go high, you need an AI and you should have an AI on hand regardless.
I would not stack Winstrol with anything too harsh and if you do stack it with something harsh, run it at a low dosage. I would stack it with maybe a little testosterone or maybe some primo.
