I'm saying I don't see a need to use more than 600mg at all. It may depend on what you're using the GPC for as well. The only study I've seen use 1000mg is the one on GH secretion, although another noted increases in GH following exercise with 600mg. Doses as low as 200mg have been shown to have some cognitive and/or performance benefits. If you're using it as a nootropic, then I'd say 600mg is plenty, and you could even try 300-400mg IMO. With 100-200mcg huperzine-A, that should be good.
1% is just the most common. 100mcg hup-A is good, you just need a little more to get there using 1% vs 2%. It's most likely capped/tab anyway though, so it doesn't make a real difference. I think 500mg should be plenty with hup-A. Save some money.
No need for >600mg, but even 200mg can be effective.
Twenty participants [10 males, 10 females; 22.0 ± 3.4 years of age; height 171.9 ± 7.4 cm; weight 56.8 ± 8.6 kg] consumed 200 mg of Alpha-GPC (aGPC-L, AlphaSize,
[Chemi Nutra, Austin, TX, USA), 400 mg of Alpha-GPC (aGPC-H), 200 mg of caffeine (CA), and a placebo (PL) in a randomized, double-blind, placebo-controlled, crossover design.

Yes, aim for 100mcg huperzine-A. You only need 1/2 the dose of 2% compared to 1%.
Why? Just use 1%. It's the same thing, and it's a small dose either way.
What sort of bottles are you using? If you have to measure anything out, it's hard enough to measure 10mg (100mcg at 1%), let alone 100mcg (1/10 of 1mg). Even at 1%, you can have 100 servings in 1 gram of powder.
What? Looking at those facts, it's 99% hup-A, so you only need 100mcg of the extract to get 100mcg hup-A (99.9mcg hup-A, but close enough). If you're using a 1% extract, you need 10mg of the extract to get 100mcg hup-A.
Dude, to get 100mcg from a 1% extract, you only need 10mg. It hardly takes up any space at all. What are you trying to mix it with? If you're mixing it with Alpha-GPC, you can have 60 servings of huperzine-A in the same 600mg as one serving of GPC. Even if you have 100 servings in whatever bottle or container you have, the difference between 1% and 2% is 500mg, which is less than 1 capsule worth of powder. It's largely trivial.
Math is off. If you bought it for $20 and there are 625 servings per bag, its .4 of a cent (rounded).
There is no need for 99% as a bulk powder. It's hard enough to measure 10mg, forget 1/10 of 1mg. There'd be 10 servings in 1mg. It'd be unnecessarily risky to measure it. Capped, its fine, but it's a terrible idea for a powder marketed to consumers. For inclusion in products, it's fine, but that's it.
Enough choline in your diet doesn't mean you can't benefit from supplemental GPC or CDP. Plenty of us here use and enjoy them.
In regards to what? There's no need for "high dose" huperzine, as it can cause sides and 100-200mcg is effective, but moderate doses of choline + 100-200mcg hup-A is a great combo, and works well for daily use.
