Hey T-Nation

Responsible , training and nutrition is perfect. I’ll also be under well advised person for a diet plan while on it.

This cycle is going to be test E only.

Just want to know people’s thoughts. I know 500ml is ideal for 12 weeks. What do people think about 250ml. Can it be efffective? For how long. ?

Thanks for your time

250 is basically a maintenance dose IMO, your better off at 500
