MetaLean GLP — Retatrutide + MOTS-c
MetaLean pairs the frontier metabolic peptide with the mitochondrial one: Retatrutide, the triple-agonist studied around appetite and body weight, plus MOTS-c, the “exercise mimetic” studied around metabolism and energy. Metabolic research from two directions. Every vial is independently third-party tested, with its own COA. (Retatrutide is an investigational compound.)

Sourced and handled to strict, defined specifications.
Discreet, tracked delivery.
What’s in MetaLean?
MetaLean combines Retatrutide — the triple-receptor (GLP-1/GIP/glucagon) metabolic peptide — with MOTS-c, the mitochondrial-derived peptide nicknamed “exercise in a molecule.” One works on the incretin pathways, the other on mitochondrial metabolism.
The theme is metabolism from two angles: appetite and body-weight signaling (Retatrutide) plus mitochondrial energy and performance (MOTS-c). Note that Retatrutide is an investigational compound. Each peptide ships as its own vial with a batch-specific COA. Full protocol and reconstitution guides are shared in our Telegram community.
Research directions

Two metabolic peptides, two mechanisms. Here’s the pairing.
The GLP-1/GIP/glucagon peptide studied around appetite and body weight (investigational).
The mitochondrial-derived peptide studied around metabolism and energy.
The stack is oriented around body-composition and metabolic research.
Incretin signaling plus mitochondrial metabolism, studied together.

Frequently asked questions
What is MetaLean studied for?
It combines Retatrutide (incretin pathways) and MOTS-c (mitochondrial metabolism) for metabolic research. Retatrutide is investigational. We share these as research directions, not medical claims.
Why these two together?
It studies incretin signaling and mitochondrial metabolism side by side. Protocol and reconstitution guides are shared in our Telegram community.
Is MetaLean GLP for human use?
No. Aeternum Life supplies MetaLean GLP strictly as a research-grade material for laboratory research. It is not sold for human or veterinary consumption.
Is a COA available for MetaLean GLP?
Yes — every MetaLean GLP batch ships with a batch-specific Certificate of Analysis covering identity and purity.
