nx_supp_ingredient.nx -- SUPPLEMENT GTM SUITE / INGREDIENT CATALOG rung. The input side of taking a supplement to market: what an ingredient IS legally, what dose the clinical literature actually used, how much volume that dose occupies, and what it costs. THE REGULATORY CLASS IS THE MOST IMPORTANT FIELD, and it is not advice -- it decides whether a product can legally exist. Two exclusions do the work: DRUG PRECLUSION (21 USC 321(ff)(3)(B)): an article approved as a drug, or authorised for investigation as a new drug with substantial public clinical trials, CANNOT be a dietary ingredient. Oxytocin (approved as Pitocin) and bremelanotide (approved as Vyleesi) are on the wrong side of that line permanently. A compounded oxytocin troche is a PRESCRIPTION product dispensed by a pharmacy -- it is not a supplement business. NOT A DIETARY INGREDIENT AT ALL: DSHEA's definition is a closed list (vitamin, mineral, herb/botanical, amino acid, dietary substance used to supplement the diet, or a concentrate/metabolite/extract of those). A synthetic signalling peptide such as Kisspeptin-10 or BPC-157 is none of them -- it is not an "amino acid" any more than a protein drug is. FDA has said so directly, and BPC-157 was placed on the 503A category-2 list in 2023 as not eligible even for compounding. So this catalog REFUSES those by construction, in the same way nx_ferment_safety refuses an unsafe ferment: a structural verdict, not a warning string a formulator can scroll past. The nine botanicals and amino acids on the user's list ARE lawful dietary ingredients and are catalogued normally. COSTS ARE INDICATIVE BULK RANGES, NOT QUOTES. They move with harvest, origin, assay, and volume, and a branded standardised extract is priced by its owner. si_cost_is_indicative() exists so no downstream model can quietly present these as a purchase price. Get a real quote before committing. DOSES ARE THE LOW END OF THE CLINICALLY STUDIED RANGE, which is the honest floor for a "clinically dosed" claim -- not a marketing dose. Units: dose in mg, bulk density in mg per mL, cost in CENTS per kg. Grounding (cited; researcher-groundable):
