I went "In Search Of" a refill of 10mg/ml of EV back in the beginning of December. I wanted to get that out of the way before my company changed insurance carriers and dealing with that "Unknown". Three months earlier, no prob. Just the typical 2-3 day delay. Well, one week delay became another, became another. THe pharmacy checked 20mg/ml, same story, "Supply Unavailability".
When I started digging deeply into the FDA data-base, apparently for 10mg/ml there is now only one "Real" (approved) manufacturer, PAR. JSP was the they brand of my last refill but they were purchased by PAR last year. For 20 & 40 concentrations there is a second source.
When I posited the issue to my TG group site, everyone else is on 40 mg/ml and have no problems.
The pharmacy was finally able to get in 40 mg/ml after a few more weeks of checking. (WalGreens. Didn't even need me pestering them. Always on top of it). Got the doc to change the script over, and..... BCBS comes back with denied. a) I am a male; b) I need pre-approval.
Que two weeks of anxiety attacks.

Then the idiots at BCBS had no idea that 40mg/ml of EV is really EV mixed with oil, in other words, also sold under the name of Delestrogen! Yet on their own mail-order pharmacy list it is EV!

(BTW - Even there they list only 20 & 40, no 10)
The part that sucks now is I need a MUCH lower volume syringe. Just one drop loss is a major total doseage loss. I get sick enough seeing that occassional drible of the elixir of life out of the injection site.
Well, I guess I can always talk to the doc about upping the dose
