A Cypionate or Enanthate testosterone might be better for you than a sust blend, in that it will keep your blood levels more consistent with your dosing protocol.
Eq is not liked around here that much, however, I have ran it with a higher dose of test. While its direct muscle building effects are quite lackluster, the endurance increase was dramatic for me. If it wasn’t so pricey, I would run it again for that reason.
I’m currently on Test(200mg/wk)/Tren(200mg/wk)/NPP(200mg/wk) and having no endurance problem (8 x 3 minute boxing rounds). Getting cut. Getting strong. Maybe you should try a lower dose if you’re an endurance athlete.
How’s your sleep on that combo (dose)? Also, what are you taking for progesterone?
GH does not require a PCT. I’d research GH more and you’ll be able to decide if its beneficial to you. If you are looking for direct improvement in your CrossFit numbers, I’d consider something else.
