150 weekly, EOD, sounds perfect.
I inject IM. I've made the mistake of changing protocols and doing some things based on perceived symptoms, and now I really want to stick with what's absolutely trusted and simple. A little down the road I might consider subQ.
As I lower the dose I am definitely planning to ditch the aromasin. I had been injecting 200mg once a week. Ten days ago, at absolute trough, I got tested, then went home and injected 100mg. The next day my results came back T 1272, E2 49. Forty-nine isn't bad considering 1272, but considering I injected after that, I decided to take 6.25 of asin. Two or three days later I woke up with wood for the first time in a long time. After my next injection I wasn't going to take the asin, but I felt incredibly bloated later in the day, so I took one based on that. The wood hasn't come back, so I definitely lowered it too much. Now I've decided at max I'll use 6.25 with every second or third 100mg injection. Then once I get the 10ml vial and start EOD, I'll cut it out completely for a few injections and see where my E2 sits then.
I have been paying for labs myself, and doing them almost weekly, so I've been going with the cheap basics. SHBG is a little more costly, but after I get going with EOD, I definitely want to test it. I originally started trt because SHBG was high-normal and free was low-normal.
