Peptides are short chains of amino acids that act as signaling molecules. SARMs (selective androgen receptor modulators) are a separate class of small molecules that act on androgen receptors. They are chemically unrelated, and both are supplied for research use only.
Side by side
| Peptides | SARMs | |
|---|---|---|
| What they are | Chains of amino acids | Small non-peptide molecules |
| How they act | Bind various receptors as signals | Act on androgen receptors |
| Structure | Peptide bonds | Non-peptide chemical structure |
| Status | Research use only | Research use only |
Two different classes
The key point is that a SARM is not a peptide. Peptides are built from amino acids joined by peptide bonds, while SARMs have a completely different chemical structure. They are grouped together only because both appear in the research-compound market, not because they are related.
Browse research-grade peptides
Every Axis compound is third-party tested to 99.4%+ purity, with a certificate of analysis on every batch.
What they share
What they do share is that both are research compounds. Whichever you look at, a research-grade product should ship with a batch-specific certificate of analysis and be labeled research use only.
Key takeaways
- Peptides are chains of amino acids that act as signals.
- SARMs are a separate class of small, non-peptide molecules.
- They act on different targets and are chemically unrelated.
- Both are research compounds, supplied for research use only.
A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
