This page compares what is documented about MOTS-c (Human) and Semaglutide, rather than ranking them by effect. What each molecule is, the sizes and prices actually carried, what the certificate covers, and how the two differ on the bench. Everything here is research-use-only material and we do not publish outcome, dosing or administration content for any compound in the catalogue.
What is MOTS-c (Human) and what is Semaglutide?
MOTS-c (Human). MOTS-c is encoded inside the mitochondrial 12S rRNA gene — a mitochondrial-derived peptide studied in metabolic-signalling and exercise-biology models since 2015.
Semaglutide. Semaglutide is the most-cited GLP-1 receptor agonist in the research literature, which makes verified reference material a staple for comparative receptor work.

At their best sizes MOTS-c (Human) works out at $2.50 per mg against $3.83 for Semaglutide — 53% more for the mg. Vial prices start at $60.00 and $80.00 respectively, which is the number most people compare and the one that says least, because the two are not sold in the same sizes. Full sizes, tier pricing and the lot certificate sit on the MOTS-c (Human) page and the Semaglutide page.
What is each one studied for?
What the published literature investigates, which is a different question from what either will do, and the only one of the two a supplier can answer.
MOTS-c (Human) is studied in mitochondrial-signalling research. Mitochondrial-derived peptides are a young and fast-moving corner of metabolic research, with MOTS-c the most-studied of the family.
Semaglutide is studied in glp-1 receptor research. GLP-1 receptor biology continues to dominate metabolic-research publishing, and semaglutide remains its most-cited reference compound.
Studied in the same area does not make two compounds interchangeable, and the research library holds the per-compound documentation.
Semaglutide vs MOTS-c (Human): how they differ on the bench
Semaglutide. Semaglutide degrades along predictable routes — our stability guide maps which storage regime suits sealed powder versus a working solution.
MOTS-c (Human). MOTS-c is a 16-residue peptide with a critical central motif; sequence-level identity confirmation matters more here than for longer, more forgiving chains.
What actually differs between Semaglutide and MOTS-c (Human)
Worth doing the arithmetic before comparing sizes: Semaglutide is 4,114 g/mol and MOTS-c (Human) is 2,174.6 g/mol, a factor of 1.9. A milligram of MOTS-c (Human) therefore contains roughly 1.9 times as many molecules as a milligram of Semaglutide, so two vials of the same labelled mass hold quite different amounts of substance. Equal milligrams are not equal moles, which is what the molarity calculator exists to convert, and it is the reason a price-per-milligram comparison and a price-per-mole comparison can point at different vials.
Identity is the other analytical axis, and it is settled per lot rather than per compound. MOTS-c (Human). Catalogued as MOTS-c, and the certificate's identity test resolves to that. Semaglutide. Catalogued as Semaglutide, and the certificate's identity test resolves to that.
Both are released against a certificate reporting identity, purity by the stated method and net peptide content, readable before anything is bought.
Which is better, Semaglutide or MOTS-c (Human)?
Neither Semaglutide nor MOTS-c (Human) is ranked against the other here, and the refusal is deliberate. Better, safer and stronger are questions about effects in a living system, and we sell neither compound for use in one — why none of these pages ranks two compounds sets out the reasoning in full.
What it does instead, for these two:
- MOTS-c (Human) is the cheaper of the two per mg, at $2.50 against $3.83.
- Semaglutide is the heavier molecule by a factor of 1.9, so equal milligrams are not equal moles.
- MOTS-c (Human) is carried in 3 sizes and Semaglutide in 5, and each lot carries its own certificate.
Every one of those is checkable before you buy.
Common questions
What is the difference between Semaglutide and MOTS-c (Human)?
Different molecules before anything else: Semaglutide is C187H291N45O59 and MOTS-c (Human) is C101H152N28O22S2. Semaglutide is the most-cited GLP-1 receptor agonist in the research literature, which makes verified reference material a staple for comparative receptor work. MOTS-c is encoded inside the mitochondrial 12S rRNA gene — a mitochondrial-derived peptide studied in metabolic-signalling and exercise-biology models since 2015.
Which one should I choose?
MOTS-c (Human) is carried in 10 mg, 20 mg, 40 mg and Semaglutide in 5 mg, 10 mg, 15 mg, 20 mg, 30 mg, each lot with its own certificate. Which of those suits the work is yours to decide; everything here is research-use-only rather than guidance for use in a human or an animal.
Do both MOTS-c (Human) and Semaglutide come with a certificate of analysis?
Neither is in stock at the moment, so in each case the certificate is the one attached to the lot that arrives. A certificate belongs to a lot, not to a product. It is linked from the product page, and reports identity, purity by the stated method, and net peptide content for the material actually in that lot.
Which is cheaper, Semaglutide or MOTS-c (Human)?
Per mg, MOTS-c (Human) at $2.50 against $3.83, taking each one's best size. By vial they start at $60.00 for MOTS-c (Human) and $80.00 for Semaglutide, which is the comparison most people make and the one that says least, because the two are not sold in the same sizes.
Is a milligram of MOTS-c (Human) the same as a milligram of Semaglutide?
By mass yes, by amount of substance no. Semaglutide is 4,114 g/mol and MOTS-c (Human) is 2,174.6 g/mol, a factor of 1.9, so a milligram of MOTS-c (Human) holds roughly 1.9 times as many molecules. Two vials with the same number on the label are not the same amount of substance, which is what the molarity calculator converts.
