What to Check When Your MOTS-C Arrives
Not every irregularity on arrival is a defect, and not every compound is defective under the same conditions. Here is what actually matters when a MOTS-C shipment arrives.
In plain English
Check that the packaging kept light out and that the powder is white rather than yellowed. Any yellow or tan tint means light damage has already started and is a genuine reason to reject the vial.
What MOTS-C actually is
MOTS-c has one of the more surprising origins in this catalogue: its instructions are written not in the DNA of the cell nucleus but inside the separate, much smaller genome carried by mitochondria — the structures that produce most of a cell's energy. It is studied as a signal they send out to the rest of the cell.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Arrival inspection for MOTS-C
Confirm the vial was shipped with light protection and the cake is white rather than yellowed. Discolouration in a tryptophan-containing peptide is a meaningful oxidation signal, not a cosmetic variation.
Storage on arrival
Documentation to check
Confirm the mass near 2174.5 Da and scrutinise the region above it for +16 and +32 Da satellites. Because both methionine and tryptophan can oxidise, multiple oxidised species may be present — a cluster of small satellite peaks is more diagnostic here than a single one.
What MOTS-C is studied for
Part of a novel class demonstrating that mitochondria encode peptides acting systemically.
The most-studied signalling interaction, examined in metabolic and exercise models.
Investigated in glucose-metabolism research models.
Studies have examined MOTS-c expression in relation to physical activity and ageing in animal models.
