I'm glad at least that one of the vendors I purchased from so far was willing to refund me without any trouble; this one being Peak Nootropics..their's is the one that is vaguely bitter and not at all sulfuric in taste, smell, or urine expelled metabolites. By effect I'd say its a latter generation racetam, peptide family noot, or else CRL-40,941....in other words, a wild guess other than doubt that it's the real thing. Kal, the owner, assures me that it's the real thing, but....Adra is sulfuric, there's no getting around that basic property. And it's true that sourcing Adra these days is going to be limited given that moda has all but replaced it for medical use globally, so US resellers are at the mercy of Chinese to-order bulk pharma manufacturers.
The other, Nootropics Depot, I haven't yet asked a refund for because I want to be as sure as I can that it's a thiamine derivative before asking for one. I'm corroborating effects and properties with Ceretropic's Adrafinil. I know that Cere and ND\Parmatrix are both based out of Phoenix, so hopefully they get the materials from more than a single source. Oh, and to boot I've got a 1st-month-free Rx of armodafinil coming to my preferred pharmacy tomorrow...this will be mostly useful as a discriminative tool since all insurances will balk at paying a dime for even generic moda unless you're a documented shift worker.
Thanks for the lead on Newstar, although they are also within the 'Arizona axis' of Noot vendors, the vendors are so willing to accept refunds for a trial purchase of this or that we can feel comfortable exploring.
I suppose that if the premise of this post is correct, which I'm hoping it is not, then at least I've rediscovered the moderate usefulness of sulbutiamine for augmenting caffeine...though not at $20\5grams ;-).
