[QUOTE="tonyfr, post: 70190, member: 15055"] From various sources, I found that:[INDENT]1 IU HCG = .1 mg HCG = 100 [COLOR=#333333]μg HCG [/COLOR][/INDENT] [COLOR=#333333] This means that:[INDENT]1,000 IU/ml = 100 mg/ml = 100,000 [COLOR=#333333]μg/ml [/COLOR][/INDENT] [COLOR=#333333] [/COLOR]And: [/COLOR][INDENT][COLOR=#333333]5,000 IU = 500 mg (not 1 mg) [/COLOR][/INDENT] [COLOR=#333333] The SIGMA Product Information sheet confuses more than it clarifies:[/COLOR] [LIST] [*]"Dilute aqueous solutions undergo rapid loss of activity when stored frozen": There is nothing that defines how dilute is dilute or how rapid is rapid. [COLOR=#333333]100,000 [COLOR=#333333]μg/ml might be considered dilute and 6 months might be considered rapid. Or perhaps rapid is 2 days.[/COLOR][/COLOR] [*]"Storage Temperature: -20°C": I have to believe this applies to the HCG which SIGMA supplies to pharmacies, which would mean the powdered form. [*]"Solutions in water at ≥ 10 μg/ml can be stored as single use aliquots at 20°C": my dilution of 100 [B]mg[/B]/ml is certainly ≥ 10 [B]μg[/B]/ml, but I don't think I should store it at 20°C. Of course, I don't have it as single-use aliquots, but I am hard-pressed to understand how that would make a difference. [*]"Solutions at 100 μg/ml in water are stable at 2-8°C for about 2-3 months": This statement only talks about solutions at 100 μg/ml, which leaves us wondering about solutions at 101 μg/ml or even 100,000 μg/ml. [/LIST] From this, I get absolute no reassurance that reconstituted HCG can be frozen. Using pregnancy strips to test for HCG is an option, but as I understand it, you can test for the presence of HCG, but not for whether potency has been reduced to 50% or 10% or whatever. [/QUOTE]
