Howdy,
The generic version is Calcionate Syrup by Rugby. It's sold in 16oz bottles for about ~$25. I bought a bottle from a local pharmacy. They needed two days to get it delivered. Just for the heck of it, a few years later, I bought another bottle of it at Costco's pharmacy when someone didn't pick-up their special order. If anyone ever needs it, local pickup only, stop by for some here

. SBCK members can hit me up for delivery at one of our group meetings

.
You can also buy it online. I never needed a prescription for the bottles that I bought.
One of many examples:
