I just got my bloodwork back today after going to the doctor about feeling lethargic and moody. I'm a 39 year old healthy male (195lbs, 12% bf, don't drink) with the following test levels:

Testosterone serum: 255
Free Testosterone (direct): 7.9


My doctor said both of these are in the low range, and has started me on 200mg every 4 weeks of test-e. After doing a bit of research, I'm a little concerned about the low dose and time between shots. If test-e has a half-life of 7-10 days, won't I be up and down every month?

Has anyone else ever started with this protocol and had decent results?
I appreciate any help.
