Peptides for Endurance: Exercise Mimetics, Examined
The exercise-in-a-vial pitch, checked against the actual data.
The quick version
- SLU-PP-332 and MOTS-c, pitched as exercise in a vial.
- Mostly animal data, and human proof is weak.
- Train first, and treat these as experiments, not shortcuts.
The goal
The goal is more stamina and a bigger aerobic engine. The trendy pitch is exercise in a vial, which is worth a careful look.
What people actually run
The two names are SLU-PP-332 and MOTS-c, both tied to the pathways exercise uses. People hope they mimic some training benefits without the training.
How it is structured
There is no settled human protocol for either. People copy animal-study doses, which is a guess. The realistic structure is to treat them as experiments layered on actual training, not substitutes for it.
What is actually supported
Be blunt about the data: SLU-PP-332 is mouse-only with no human trials (Billon et al., 2024), and MOTS-c human data is mostly about your own levels rising with exercise, not injecting it (Reynolds et al., 2021). Exciting pathways, weak human proof.
The common mistake
The mistake is buying an exercise-in-a-vial story and training less. The evidence is about exercise driving these molecules, so the training is the point.
Bottom line
Endurance peptides are an interesting idea with mostly animal data. Train first, and treat these as experiments, not shortcuts.

Reminder: I am not a doctor and this is not medical advice. It is my own notes and reading of the research. Peptides sit in a legal grey area, research-grade is a real category, and it is on you to verify your own compliance. Talk to a qualified professional before you start anything, especially if you take other medication.
