no one ran masteron here before???[/QUOTE
Is it Mast Prop or Enanthate?
If it's Mast Prop, I would run it at least eod. 100mg minimum.
If Enanthate, then 400/500mg a wk is fine.
You could even do 2 on 1 off combined with you Test and Tren.
What kind of Tren and Test are you running, Tren a or e?
I have a buddy running 100mg of each Tren a, Prop and Mast P ed.
