## Description

This Metabolic Stack brings three peptides from separate branches of metabolic research — semaglutide, AOD-9604 and MOTS-c — each sealed in its own freeze-dried vial. Every one acts through a different biological system, and the kit is designed for experiments that must keep those systems distinct rather than mixing them in one preparation.

Semaglutide activates the GLP-1 receptor over a long period; it is built on the natural incretin sequence, with an Aib residue at position 8 to resist DPP-4 and a C18 fatty diacid chain that binds it to albumin in the blood. AOD-9604 has nothing to do with incretins: it is an altered piece of human growth hormone (residues 176-191) with an extra tyrosine at the start, investigated for effects on fat metabolism that are separate from the growth effects the whole hormone produces via its receptor. MOTS-c is a 16-residue peptide whose gene lies in the mitochondrial 12S rRNA, studied in relation to AMPK signalling and mitochondrial metabolism.

HPLC confirms ≥99% purity for every vial, and each has a certificate for its own lot. Because nothing is mixed, the three can serve as separate study arms, as controls for each other, or be combined however your protocol requires.

## Frequently asked questions

### Why put these three in one kit?

Each represents a different way of influencing metabolism — activation of the GLP-1 receptor, a fragment analogue of growth hormone, and a peptide encoded by mitochondria. Covering receptor signalling, fat handling and mitochondrial energy in one panel gives a broader picture than three variants of a single pathway.

### Is there a certificate of analysis for every vial?

Yes. Each vial comes from its own production lot and is released with a certificate confirming its peptide's identity and HPLC purity — three documents in all, and we can send the latest versions before you order.

### How should semaglutide be reconstituted?

With care: it is a large, fatty-acid-modified peptide that is sensitive to rough handling. Let the bacteriostatic water run down the inside wall of the vial instead of hitting the powder directly, and swirl rather than shake — foaming is a sign you are losing peptide.

### Can the components be used at different times?

Yes, and that flexibility is the reason for separate vials. Kept sealed, frozen at −20 °C and shielded from light and damp, the freeze-dried vials remain stable for more than a year, so a protocol can bring in each component when its phase begins.
