I took weekly shots at 100mg. Cypionate is usually prescribed in the US. Enthate everywhere else. Monthly is way too long. Most doctors recommend every two weeks. However, there was a new report (http://rd.springer.com/chapter/10.1007/978-3-642-72185-4_11) that shows the half life (http://www.muscletalk.co.uk/articles/article-steroid-half-li...) of which they thought was closer to 12 days is actually something like 8. So at the end of the second week you're likely to start feel physical effects again (I know I do). Let me see if I can find it.
What about pellets/implants? Aren't they supposed to release more consistently over a longer period?
Please excuse my ignorance on this, I am in Canada, have been blessed with naturally high T levels, and have no experience with anti-aging clinics, but I'm fascinated by the subject.
Orals shouldn't be considered.
