From manufacturing partner to purchase
Every MOTS-c lot follows the same path. The later steps are published, so you can check them for any lot.
- Qualified manufacturing partner MOTS-c research material is produced by a qualified manufacturing partner within MOTS-c Research Supply’s supply chain.
- MOTS-c Research Supply specifications Material is produced and evaluated against MOTS-c Research Supply’s defined specifications and quality requirements. Details
- Incoming and batch documentation Each batch is documented on receipt and assigned a lot number, printed on every vial label.
- Independent analytical testing Samples from the lot are tested by ILS Laboratories for HPLC-UV purity, HPLC-RTM identity and net content, with endotoxin and PCR where listed. Details
- Lot review and release Results are reviewed against the stated specification (≥95% HPLC-UV purity, identity confirmed by HPLC retention-time match against a reference standard) before release.
- COA and analytical record The lot record and laboratory certificate are published under the lot number. Details
- Lot verification Anyone can look the lot up and confirm the result with the laboratory. Details
- Purchase through Klow.bio Released lots are available through Klow.bio, the purchasing platform operated by Klow Labs. Details
Controlled supply chain
MOTS-c Research Supply works with qualified manufacturing partners and maintains defined specifications and quality requirements for MOTS-c research material. MOTS-c Research Supply is not the physical manufacturer; its role is to control what is sourced, document each batch, have it tested independently and publish the results.
Defined specifications
MOTS-c Research Supply’s stated release specification is ≥95% HPLC-UV purity with identity confirmed by HPLC retention-time match against a reference standard of 2174.62 g/mol. The full specification, from molecular formula to physical form, is published on the MOTS-c specifications page.
Independent analytical testing
Testing is performed by ILS Laboratories, an independent laboratory, not in-house. Instead of a "third-party tested" badge, each lot's actual results are published: current lots report 99.90% purity, with identity confirmed on every lot. How each test works.
Lot-level transparency
Any vial can be traced in one path: product, lot number, testing, certificate and verification. Start with the lot number on the label at buymotscpeptide.com/verify.
Availability
Released lots are available through Klow.bio, the purchasing platform operated by Klow Labs, which also operates MOTS-c Research Supply.
