Is my HGH still good?

I have some HGH from China that is about 12 to 18 months old. Its been kept at room temp. Do you think its still good?

Thanks,

Most packs say room temp for 7days, then they need to be refridged...not sure I would count on it.

But do you think it would be unsafe too use? Its still in powder form.

Thanks!

I would give it a try, im sure it will be deteriorated (less potent) but I dont think it will be harmfull to your body.

I agree with Cordoba. Some of the 191 amino chain hgh's dont call for refrigeration before reconstitution and some do. Since they are all the same chemical compound it only makes sense to me that there must be little degredation from keeping at room temp. The fridge is definitely the preferred storage location though.
