Tiers name what a vendor publishes, not a verdict on any product's purity or quality.
Lab-verifiable COAs: certificates that open on the testing lab's own site (the seal's ring shows what share of them do).
Third-party COAs: certificates attributed to a third-party lab, which may be hosted only on the vendor's site.
Tiers follow the Vendor Score (90+ and 80–89), which is 87% COA evidence; the numeral in each seal is that score.
Affiliate relationships never affect tiers, selection or order. How the Vendor Score works
A monoamine-reuptake-inhibitor small molecule studied in research on appetite and metabolic pathways.
Evidence brief
Tesofensine is an oral triple monoamine reuptake inhibitor (it blocks presynaptic reuptake of noradrenaline, dopamine, and serotonin); it was first tested for neurodegenerative disease, where unintended weight loss was noticed, and was then redeveloped as a candidate anti-obesity drug.

● Tesofensine blends & stacks · 4 first-partypriced by total — not $/mg
Multi-peptide products (e.g. BPC-157 + TB-500). We don't rank these by $/mgPrice divided by the milligrams of active compound — the like-for-like way to compare cost across different vial sizes.Price divided by the milligrams of active compound — the like-for-like way to compare cost across different vial sizes. — a per-milligram figure across different peptides isn't comparable — so they're listed separately by total price and kept out of the headline index above.

Research use only — this reports what an FDA label or a peer-reviewed study published, tied to its species and study context. It is not medical advice, not a recommendation to use, and no dose here is generated by pepmg. Any dosing decision is for a qualified professional. Animal-study amounts do not establish a human dose.
All products listed are sold by third-party vendors for laboratory and research use only (RUO). Where an FDA label or a peer-reviewed study has published a dose, pepmg reports it with the source named, because that is safer than guessing. It is a report, not medical advice and not a recommendation to use anything. pepmg sells nothing and ships nothing. Listings are price-tracking data, not endorsements.
