Peptides are chains of amino acids that act as signaling molecules. Steroids are a separate class of lipid-based molecules built on a distinct four-ring chemical framework. They are unrelated classes, and both are supplied for research use only.
Side by side
| Peptides | Steroids | |

| Built from | Amino acids | A lipid-based ring structure |
| Chemical class | Peptide | Steroid |
| How they act | Bind receptors as signals | Act through steroid pathways |
| Status | Research use only | Research use only |
Two different classes
A steroid is not a peptide. Peptides are amino acid chains; steroids are built on a completely different, lipid-based framework. The two are separate chemical classes that happen to both appear in research-compound discussions.
Browse research-grade peptides
Every Axis compound is third-party tested to 99.4%+ purity, with a certificate of analysis on every batch.
The common ground
Both are research compounds, so the same standards apply: a research-grade product should ship with a batch-specific certificate of analysis and be clearly labeled research use only.
Key takeaways
- Peptides are chains of amino acids; steroids are lipid-based molecules.
- They are built on completely different chemical frameworks.
- They are unrelated classes that both appear in research.
- 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.
