Most people say 8-10 weeks for tren ace but it seems people are using it for up to 12 wks... First time using tren and this will be my 7th cycle in the past four years.... I am going to be doing a prop tren cycle Prop 100mg ED tren 50 mg ED and was thinking running the prop for 15 weeks and the tren for 12wks... So I wanted to know if you will still keep seeing gains up to twelve wks using tren or is it a waste to go past 10 wks???
