The research question

Metabolic signalling isn't one pathway

Metabolic research runs at two levels: the receptors that carry the incretin signal, and the cellular machinery that acts on it. This stack is built to let a study look at both, and to compare a single-pathway agonist against a dual-pathway one under the same conditions.

Compound by compound

What each one does, and why it's here

Mechanism as described in the research literature — what each compound is studied for, and the point on the chain it sits at.

MOTS-C research vial
Cellular level

MOTS-C

10mg · MOTSC-10

Mitochondrial-level regulation

View COALot MC0001
What it is
A 16-amino-acid mitochondrial-derived peptide encoded in the 12S rRNA region of mitochondrial DNA.
Studied for
Investigated for AMPK activation and its role in the folate–methionine cycle, and studied as a regulator of metabolic homeostasis and substrate utilisation.
Why it's in this stack
Both compounds above act at receptors. MOTS-c is studied a level down, inside the cell — which is why it is commonly run as a parallel arm rather than a substitute.
Research articles The mitochondrial-derived peptide MOTS-c promotes metabolic homeostasis and reduces obesity and insulin resistance
In unison

Why these are studied together

Each compound sits at a different point on the chain. Ordered together, they let one study cover the whole sequence instead of a single step.

  1. 1 Single pathway The single-receptor baseline
  2. 2 Dual pathway The dual-receptor comparison
  3. 3 Cellular level MOTS-C Mitochondrial-level regulation
Mechanism, not outcome. Everything above describes pathways these compounds are studied for in the literature. It is not a claim of effect, a protocol, or a dosing guide. These products are supplied strictly for in-vitro laboratory and scientific research, are not approved by the FDA, and are not for human or animal consumption.
Why bundle it

Sourcing is the slowest part of the study

Assembling it yourself

  • Three or four vendors, each with its own lead time
  • Purity claims you cannot verify before delivery
  • Mismatched lots with no common documentation
  • Solvent ordered separately, or forgotten entirely
  • Multiple shipments, multiple failure points

The Metabolic Stack

  • One order, one facility, one shipment
  • ≥99% purity guaranteed across every component
  • A certificate of analysis tied to each vial's lot code
  • Bacteriostatic water included and sized for the stack
  • Dispatched the next business day via priority shipping

Questions

About this stack

Why are these named Peptide S and Peptide T rather than the compound names?

Compounds in this category are listed under research designations. The specification, SKU, molecular formula, and lot documentation on each product page identify exactly what you are ordering.

Which size should a new research program start with?

Each compound is stocked in a single vial size. For quantities beyond the listed range, contact us and we will quote it directly.

Are these compounds controlled substances?

No. None of our products are controlled substances under the Controlled Substances Act. Purchasers remain responsible for compliance with all applicable federal, state, and local law.

How is purity verified?

Compounds are produced in a cGMP-compliant, ISO-certified facility and submitted for independent third-party analysis. BioStem Labs guarantees a minimum of 99% purity, and the certificate of analysis for your specific lot documents the result.

How do I find the COA for the vial I received?

Use the lot code printed on the vial label. Enter it in the COA lookup and the matching batch record will resolve, along with the size and SKU it belongs to.

When will my order ship?

Orders are picked, packed, and dispatched on the next business day with priority shipping. A tracking number is issued as soon as the carrier takes possession.
