I have seen several threads asking for advice on headaches and libido issues and thought personal experience might help. I'm now on TRT from many yrs of AAS use. 42 male, 220, 10% bf, work out every day. When i was put on TRT 200mg wk test e, .5 adex eod, and he wanted me on hcg 250iu every 2 weeks but I decided not to do that for now. I would experience severe headaches 2 days after the shot and would last for 4-6 days. BP would raise a little but not what I thought was extreme. I started losing all desire in the sex dept and thought after my labs it was my E2 was too high, 35. Doc was confused so I started my own testing. Here's what In found. After many different dosages and serms I started over. It was pretty simple .25 mg of Lisinopril for BP. got rid of all the adex. take only 200mg of test e biweekly and 250 iu of hcg on third week. Although I thought my BP was in the great range it would raise enough to get the headaches, they are gone completly. Libido came back after a week of stopping adex. I am now more active in that dept than before. Point is, each of us is different, our body composition is designed to respond differently than the next guy. I found E2 levels would like to be in the 25 range but for me my body chem responds to 35-38 range. I also realized very suttle changes like the BP can cause huge changes in how we feel. 15 yrs ago I would cycle very heavy and had no issues at all, age has changed all that. Also be patient when making changes, dont expect the body to respond over night, it took the BP meds about a week to help. And by all means read what the great group of fellas on here have to offer. I have never seen a finer group of guys willing to help with free info than you can find on here. And last keep in touch with your doc. Get labs. They have an off the wall approach most of the time but do your research and you will find what works best for you. Hope this helps.
