there is no need.
using an Aromatase inhibitor (AI) from day 1 will just tank your estrogen while your still waiting for your test to reach levels.
This makes no sense whatsover. When you do an injection of 200mg your T levels will peak from that shot within 48 hours, then they will start a slow steady decline. You can bet your ass that this will cause increased aromatization. Not to mention the fact it takes most AI's at LEAST 5 days to accumulate in the blood.
HCG is to keep your balls from suffering atrophy which you wil not experience this early in the cycle.
first of all your HPTA will begin to shut down within 48 hours of your first injection. Testosterone is just a messenger signal, nothing more. It regulates the speed of many things in the endocrine system. as soon as serum T levels rise, which is within hours of your first injection, you have more T in your system than before the shot. so since the signal is stronger it will imediately begin to alter the speed of other mechanism's. slowing down GNRH production.
keep an Aromatase inhibitor (AI) on hand to keep your estro in check and using a longer ester like enanthate you wont start to aromatase untill week 3 or beyond.

we went over this already............
people get very confused on what it means for a long ester to "kick in" after 4-6 weeks. Your levels steadily rise right from the first shot. It is within 4-6 weeks that levels will reach their peak and stabalize. Although they will be over physiological range the majority of the time right from the first shot.
To add to that, HCG is not just to keep the testicles full, although it is wise to do so. Testicle size is a very poor indication of function. The leydig cells only make up like 10% of the testicles.
It is EXTREMELY important to "blast" your HCG during the T decline. meaning right after your last shot of T up to post cycle therapy (pct). The reason for this is because at this time you will stimulate GNRH. GNRH controls more than just FSH and LH.
GNRH gives your testicles the material they need to make testosterone, not just turning into LH and FSH.
Its like me telling you to make a snowman. I can tell you over and over to build a snowman(clomid stimulating LH). If there is no snow (GNRH) then I will not be able to build one.
