In regards to HCG shelf life

So I've had a couple amps of GR's Pregnyl HCG in raw form in my fridge for about seven months now. I was curious as to whether or not they would be trash at this point. So I mixed up my normal ratio of 5cc BAC:5000iu HCG.

It took about 50 units (500iu HCG) on the slin to adequately wet the test strip.. And within 30 seconds a positive result.

I will test each amp as I use them, and by the time I reach the last one it'll be a year or so in storage.

if its in raw form and not mixed yet it will last a long time

I had heard mixed things and wanted some concrete experience.. I might get more and let one of the Amps sit for a year or so more and see how they fair.
