Testosterone injections will not cause decrease of testosterone serums when gels often due to absorption issues teasing the system to turn off its own level. This results with guys starting at total 330 and several days ending up with lower levels after starting some in the 150 lower ranges.
This is why guys prefer injections over gels
If a person has Pre-existing Adrenal issues (many have) before starting TRT high levels of testosterone for prolong time will push the person into Adrenal insufficiency faster then at levels of peak of 900 and troughing at 600. To high of testoSterone may cause thyroid suppression by increase TSH In many cases which I have seen in doctors cases. As a result, the anti-aging doctors stick the patient in armour thyroid creating another clusterfuk. When all they had to do is lower the testosterone in the first place and address other issues such as enviroment or infections etc. Again each practitioners has their own approach. I prefer using the least amount and addressing other factors to make the testosterone work to its maximum capacity. My goal is to get doctor’s patient dialed in on 40-60’ngs of test a week
