Yes, back in 2012-2013 (it was the actual raw base that was unavailable - meaning *all* IM Testosterone was unavailable, for months, throughout *all* of North America). But back then, we still were dispensed the 10mL vials. One lasted me about 8 months, so I wasn't affected. There was another instance I want to say around 2015, but the pharmacy sorted that quickly and came through.
If there were a shortage like in 2012-2013 again and you don't have a stockpile, you're pretty much SOL. You have no choice but to wait it out. Or if your doc's really cool and reachable, maybe to switch to something else (patch, gel, cream, whatever actually isn't shorted).
Ironically, where I absolutely wasn't able to before, I am
now able to stockpile "extra" T, courtesy of the CDC's crusade against both multi-dose vials (for home use) and also single-dose vials being used as multi-dose vials (in clinician's offices and at home). This great inconvenience has worked out into a pretty nice little loophole for me.
Basically, by their own rules, physicians cannot prescribe and pharmacies cannot dispense these wee 1mL vials cumulatively in a way that would force us to double-dip into these "single dose" vials (even despite controlled substances legalese; FDA hates you getting even a drop "extra". That is otherwise what would happen sans these new rules). Because they're not made the same as multi-dose, they are theoretically more susceptible to vial contamination (which if that happened, you see, they'd be liable and open to litigation if it weren't prescribed and dispensed as one vial per one dose). They must therefore prescribe one vial per one dose. So anyway, I happen to need half of one of these vials. I therefore can and have been drawing two doses per to net myself an "extra" 1mL vial after every two doses. I have now for well over a year. No problems whatsoever. I store, handle and use my vials correctly (a lot of people, if CDC data is to be believed, 55% of people, don't; that's why the CDC got onto this crusade to begin with; against the 10mL vials in particular).
I fill new scripts as always, but store those new vials. I use my older "extra" vials first. Also good to know, the "expiration" isn't actually an expiration. It will reduce in potency, slightly, beyond that date but it's only actually expired when its cloudy, off-color or not as viscous as it should be (I've read that takes well beyond 5 years and typically only when the vials have been stored improperly).
Let's just say, by now, even if there were a year's shortage... well...

Unfortunately, this arrangement wouldn't be doable for everybody. For those it wouldn't, I really feel bad. Shortages are not rare. They're common. And it sucks. Hell, it even being a CIII with extreme hoops to jump through just for that factor, sucks. I am still routinely 1-2 weeks overdue in actually getting my scrips filled for that because they're not allowed to even order it in advance of that date (doesn't matter for me now, but... still. Completely ridiculous).
