Ok so this used to only happen to me back when I got up to and over a gram of test (haven’t been there in a long time) but Iv been noticing after my test 250/300 shot every 5/6 days I feel tired and have brain fog for three days after my injection and I feel great for a day or two before my next shot.. Could this be estrogen or what?? 250/300mg shot shouldn’t make me feel that way so idk what’s going on.
