@HughJasolphd, .4 cc of Cypionate every three days is a bit high, hence the 1200 ng/dL.
I would advice to keep in the range of 800-1000 ng/dL which might be .3 ccs every 3-4 days.
Also propionate might be a better choice if you don’t mind subcutaneous (in the belly fat) shots at 15-20 mg daily. Propionate holds a short-acting ester so you hold less side effects with acne, DHT, etc. as the body is less saturated with superfluous T during the breakdown of the long acting ester present in Cypionate/Enanthate. Mostly FL pharmacies hold the propionate.
I hope you are mitigating the DHT in some fashion, as if you not losing hair, in the long term you might. Avodart is top choice as it also mitigates DHT’s effect on the prostate, which over the long term can be aggravated.
Btw many doctors have abandoned the use of AIs as recent studies have shown the importance of estrogen’s multi-faceted role and deleterious LT side effects by mitigating too much of it. Just keep the diet clean and you will do fine without an AI.
