Im on testosterone replacement therapy (TRT) and cons would be having to inject weekly and balls will shrink along with killing your sperm count. But if those matter you can get and Human Chorionic Gonadotropin (HCG) for the ball and spermies or just stop if you need to get somebody prego. Pros are you can actually feel normal at least I do. I mean testosterone replacement therapy (TRT) is for anybody on a clinical defiency of Test usually less than 241 on total count. Now if you dont really need it and just want to maintain a constant dose like testosterone replacement therapy (TRT) you would be on about 100mg to 200mg a week, and I guess you would call it a continuos cyle at a low dosage.
But pros I have seen is better weight management, muscles firmed up, sleep better, less anxiety and better libido. A lot of guys get on an Anti E and Human Chorionic Gonadotropin (HCG) which I dont need an E but would like Human Chorionic Gonadotropin (HCG) to keep my balls normal. But I am still going through the diagnosis stage.
Last con is more than likely you will be jumping through some hoops to get on a regimen. Some guys get thrown everything at once which is either lucky or dangerous as not everything was checked out first, which i prefer the latter. Doctor should do a full panel to check Test, E, prostate, liver, lipids, LH and FSH, prolactin Etc. They may check cortisol which is fun pissing into a jug for a day and they may also do a MRI on your pituatary. I started with a DOC and now with an Endo, I have been on Ethanate, Gel and now CYP. . More than likely you will run through a few protocols and test. Currently I am waiting to go to Uro as my final step. I have to go through the Va and its been about 4 months, which is long but from others have done doesnt seem totally out of the ordinary.
