I have been doing this for a little over 2 years.
I cruise on:
200-250mg test enanthate or cyp
blast is generally:
750-1000mg test of some sort
300-600mg deca
sometimes an oral,,usually var at 100mg/ed
I'll cruise for 3 months or longer, and try to ensure I'm cruising for 8months plus out of each year.
Im mid 30's and my natural levels were shit when I started this a few years ago.
Blood work every few months to keep me honest, and make sure I'm not fucking myself up.
I started 2iu gh/ed about 2 months ago, and plan on staying on that dose for at least a few years.. see how it helps things.
