Im on 160 units a week
160units?
Like 160i.u.? That'd be 1.6cc per week so 320mg per week.
Consider average trt/hrt dose is 200mg every 2 weeks (100mg per week), you're running 3x what a "natural" level woyld be.
I maintained 225-235lbs on 200mg every 2 weeks in prison eating shit food for 5years and training 5 days a week.
Even if by "units" you mean 160mgs (i assume english isnt your first language... If it is, id wonder why you're here asking these questions... You should know the answer before starting to use anabolics in the first place)... Anyways, 160mg per week isnt ideal , its still 60% more than bbasic replacement dose.
Rather see you you 500mg per week.
