TB500 shelf life

[funkd0c]

I have an un-reconstituted bottle of TB500 that’s been in the closet for about 2.5 years. Is it still good/effective if i were to use it now?

The way I understand as long as it is still in powder form it should be ok

2.5 years is pushing it. a lot of companies say to freeze it if you're not going to use it, and they say it'll last for 9-12 months in the freezer. only 6-8 weeks on the shelf...
