Active life question - Steroid profiles

[Toenail Juice Z]

You need to find the useful half life and not just the Half Life of the compound

For Test E, you need to inject once every 3.5 days in order for blood levels to be consistent.

How long the compound stays in your system is a different matter all together

The enanthate lasts approx 3 weeks after last shot. (Not including metabolites). I always inject every 4th day.

Anyway, thanks, but that wasn't my question though.
