hcg and room temperature

[die2live]

I have always been "told" but have no confirmation that HCG is viable (lyophilized form) before reconstitution for about 6mos at room temp. Once refrigerated or frozen the time is significantly longer (2 or more years). Once reconstituted it only remains viable at room temp for 5-10days as I recall, but refrigerated can be viable for up to 4 mos. possibly a bit longer.
