Start off with a little less if you're worried it's too much, but you need to get that estrogen under control quickly.
The test injections are giving a roller coaster effect. You're hitting the sweet spot when you first inject, it takes about two days for test c to peak then it steadily falls.
You injected more and encountered same result. Your body reacted to the initial boosts, but excess converts to estrogen. Not a good thing for men. You can develop breast tissue gynecomastia and there are other bad things associated with high E2 levels.
Your estrogen lab at 111? Are there ranges listed in your lab results? No offense but you must not be very lean, as the testosterone aromatizes more with high body fat percentages. You will continue to feel bad until you get estrogen under control. You can do that with an anti-aromatase. Google research chemicals for anti-aromatase.
Back down on T injections and if you are not injecting subcutaneously, give it a whirl. See video:
