Gabapentinoids Method for figuring out exact dose of gabapentin in a tablet?

[Antares]

Perhaps an odd question. There's a certain manufacturer of gabapentin I've been getting for months that seems to fundamentally work worse than the many other generics of the same dose (also in tablet form) I've received from the pharmacy in the past. When I first got switched to this manufacturer, I started getting headaches all the time. I'm not having that issue as much at this point, but I do have a legitimate reason I was prescribed them, and I still feel like they're underdosed. Trading them with a friend who's also prescribed (but takes capsules of a different brand) for a day caused the friend to develop dizziness (meanwhile I felt better on their capsules). What are my options for finding out for a fact how much gabapentin is in one of these tablets?

Normally I wouldn't waste so much time, but trying to get the pharmacy to order or find any other manufacturer ultimately resulted in the options of "go to Illinois to get less than 1/3 of your prescription's worth" or "change pharmacy systems entirely and hope for the best." Not for their lack of trying, either. But those options are annoying and I'd rather find out if these things are a scam if they're going to flood my area's pharmacies and work worse. Just need to know how to check the actual dose in a tablet.

Possibly relevant info on the tablet's makeup (and woo hoo, talc in my every day pills for no reason, I love America):

Active ingredient: Gabapentin, USP

Inactive ingredients: Corn starch, copovidone, poloxamer, and magnesium stearate. The film coating Opadry Whitecontains hydroxypropyl cellulose and talc.

You would have to send it in to a lab for a quantification analysis. This would be expensive. Not sure what labs are even open to the public for this purpose, though you may be able to find one.

I think the binders, etc., might matter as well. Varied absorption could be an issue.

Yeah, they might differ a bit. As comparison, here's the ingredients from the generic they used to give me all the time:

Active ingredient: gabapentin
Inactive ingredients: copovidone, corn starch, crospovidone, hydroxypropyl cellulose, magnesium stearate, microcrystalline cellulose, and talc.

Lacks the poloxamer and has two other things instead. So it's possible. Finding a lab for things like this seems very difficult.
