750 mg test e, test being the primary hormone responsible for muscle gains, so in my opinion one should use the "primary weapon" to maximze muscle gains.
no other anabolic can defeat testosterone.
and its cheaper....
might as well run all three compunds together. i personall use 550mgs of test to cruise. so, even 750 might be on the low end for me, but the primo and the eq should be just fine.
Depending on your first cycle (which should have been a low dose of just test), I would suggest sticking with a low dose of test or only bumping it up a little. My first cycle will be test 300mg/wk. Keep cycling with lowest dose possible until you stop responding then up it a LITTLE and stick with that dose until you stop responding, so on and so forth... Don't really see a huge need for other injectables or orals. IMO
