I am also interested in a non-stim creatine/NO" all-in-one" product. Thermolife's Pump-Bol looks promising at <$30. It has nitrates which are becoming a big hit.
I think VPX's NO Synthisize is caff-free, but a little pricey.
APS has Creatine Nitrate caps that should do well if you are looking for a capped product.
I'm sorta big on nitrates right now... I've been using Thermolife's Vasolate first thing in the morning and before bed, which contains Leucine Nitrate, and I swear I get a good pump without even excercising. It's wierd. May have nothing to do w/ the nitrates, though... who knows.
