that dosage is going to be different for everyone dependent on their estrogen and progestin sensitivity as well as what dosages and compounds their cycle entails. so it could be 200mg per week or 400mg per week for someone super progestin sensitive.
however, why not just run a higher anabolic dosage so you can get the "therapeutic" benefits on top of the anabolic benefits . I mean if your going to be using Mast on cycle anyways, run a sufficient dosage (400-800)
