[QUOTE="EmpowerPharmacy, post: 49347, member: 109"] Lawrence Trissel did a stability study that showed that freeze thaw cycles do not affect the potency of Trimix (Papverine HCl / Phentolamine Mesylate / Alprostadil). The only ingredient in Trimix that is affected over time under refrigerated or room temperature was the Alprostadil. About 8% alprostadil loss occurred in five days at room temperature; under refrigeration losses of about 6% and 11% occurred after 1 and 2 months, respectively. Frozen at −20°C and −70°C, less than 5% loss of any of the drug components occurred in 6 months. Room temperature exposure should be limited, and the vial should be returned to refrigeration/freezing as soon as possible. I am not aware of any of these studies being done for HCG. That being said, freezing is part of the lyophilization process that HCG must go through before it can be dispensed, so it's probably safe to say that freezing it once or twice doesn't significantly affect its potency.
