I use the Va and have never been on anything more than 7 days, If you do use the Va try using a urologist not the GP or the endo. My GP started me on every 7 days but left it at that, and wasn't open to anything. I went to the ENDO and they were terrible, tried to make me do gel even after I was doing good on injections, felt like crap and got put back on injections. Then asked about HCG for fertility and they are not allowed to do it as its no in the formulary and they didn't agree with it.
So I went I asked to go to the URO. He kept me on injections, he tried doing an exception for the HCG but it was denied, pretty much told me they wouldn't grant it except for like missing a nut or something. But he wrote me a script for HCG that I could take and get it anywhere. I started out walmart as it was like 200 bucks for a 10,000 IU vial which last roughly 3 months, I bought a $4 a month script card and HCG at walmart cost me $86 bucks for the same vial. He did sperm analysis' which was contracted next door but was fully paid for by the Va. But if you aren't interested in fertility Id skip the HCG mess, if you ask me, just my opinion.
Now AIs that's a tough one you can get them the Va carried it but are very stringent with it, unless your labs show high and you have major signs you wont get it. Which is a little extreme, but I don't know if I buy taking it small doses to start as precaution as many do here, as why take it if you don't need it. I don't seem to need it. My uro personally likes to see a 10:1 ration, so if my test is 500 and im in the 50 range Im good. The Va also is going to keep you in the 400-700 for total test, which IMO is adequate, maybe not great but adequate.
I have been getting Test for 2 years now with needles for free from Va.
But they are right once a month you will feel like garbage, even the instructions say 2 weeks. But its widely known 7 days is the average and where you should be at. Really your going to feel worse then before. Better of taking the gel at 4 pumps a day or something.
Ask to see URO, they should let you. While your at it with Va get all the test done, they should do an MRI of your pituitary, get bloods for thyroid, liver, kidney, prolactin, PSA, LH and FH, feratin, get the cortisol jug test. They should be testing these anyways to ensure its nothing something else, and a minimum gives you a baseline before you start test.
