How do you know that "potent" steroids will make u lose your hair? Have u experienced this in the past? Most steroids don't cause u to lose your hair but if balding is in your family then it may speed it up.
If it were me I would run the t-bol. It is better for size / mass then anavar. I'd say 50-60 mg per day for 6-7 weeks should be good. Make sure to run liver protection. Liv52 or milk thistle is good.
