Pregnyl has been out of stock/backordered at all of my local pharmacies for the last few months. I posted about this yesterday, but Rite Aid finally got me a generic HCG made by Fresenius Kabi, $199 for two 10mL vials, and my body seems to respond to it as well as as I've responded to Pregnyl. Anecdotally, I have not felt as good on the generics I have bought from Reliable over the last few years, my body seems to really like Pregnyl specifically and other members report the same, so this is a welcome development. As I theorized elsewhere, the positive response to the FK generic may have something to do with Fresenius buying Merck's biosimilars portfolio a few years ago.
Anyway, it's not just you, it's hard to find in stock. Reliable is perfectly serviceable, I just haven't felt as good on Sifasi, ZyHCG, etc as I do on Pregnyl. YMMV.
