300 mg of test enthanate a week will give a normal person VERY HIGH YET still in the normal test range(unless it was above average to being with). HOWEVER fina shuts you hard so you will need that much just to stay above baseline, but its a progressive thing. IMO if your purpose is only to keep sex drive you don't even need it till at least week 3 and some can go much loner from what i read it all depends on the purpose man. Some people can do a fina cycle for 5 weeks and have an ok sex drive the whole time without any test in it. If your gonna do it i would try 300 mg a week. The earlier you start the less you need.
