i bought some 99% alpha gpc from nootropics depot and it was packaged in airtight plastic and everything but when I opened it up the product is all clumped up and hard. Is this still good to consume?

99% GPC is VERY hydroscopic. We have tried to keep in managed by using silica packs, oxygen absorbers, and recently sealing it in a vacuum bag. However, it still loves to find any little moisture in the air. It kind of comes with the territory with 99% GPC. It's still perfectly fine to use. You can just crush up the clumps with a spoon, and still use it just fine. It's just a bit clumpy. If you left it out for a while, and it became a gel, then it would be much harder to use. Just always seal it back up ASAP after getting your dose out, and keep it out of heat and humidity.
I actually spoke to a company yesterday about desiccants, and learned a lot. Apparently silica gel is only efficient at absorbing water at low temperatures and high humidity percentages. The issue with that is that GPC is very good at absorbing moisture at low concentrations and high temps. So the silica pack in the GPC jar is not absorbing the moisture as well as the GPC is. There are a few other desiccant types out there that have different properties. One is called a molecular sieve. That is much more efficient at absorbing moisture at low concentrations and higher temps. I just ordered 40,000 packs of them. We are going to start using those in our products instead of silica. It's the desiccant with the best characteristics for absorbing moisture from jars and bottles. It's so efficient, it will absorb moisture from fully saturated silica gel itself. So I think it will perform much better in the GPC jars.
Anyway, the GPC you got is still fine to use. It was synthesized less than 2 months ago, and has been stored properly. It's just very hydroscopic. You'll find crushing up the chunks to be easy. Hopefully these new molecular sieves will take care of the issue fully, though.
