How would you dose 50mg per week? Tren Ace is a short acting ester. You need to use it at least every other day, so tren ace at 50mg per week would be like 12.2 mg oed. That is silly.
Tren Ethanate on the other hand can be used in small does feasibly. I just finished 10 weeks of 100mg Tren Ethanate per week and got terrific results. but I also ran 100mg test per week.
