IGF-1 LR3 vs Sermorelin
Two secretagogues and analogs compounds, compared by what each molecule is: class, length, mass, origin and what it binds, side by side. Nothing here compares what either one does.
Specification
Side by side
| IGF-1 LR3 | Sermorelin | |
|---|---|---|
| Class | Recombinant IGF-1 analog | Synthetic GHRH(1-29) analog |
| Residues | 83 | 29 |
| Sizes | 1 mg | 10 mg |
Origin and target
Where each one comes from, and what it binds
IGF-1 LR3
Origin. A modified insulin-like growth factor 1 analog, extended at the N-terminus and substituted at position 3.
Target. The IGF-1 receptor family. The modifications reduce its affinity for IGF binding proteins.
Full referenceSermorelin
Origin. The 1-29 fragment of human growth hormone releasing hormone, the shortest fragment retaining the parent sequence's activity profile.
Target. The GHRH receptor family.

Handling
The same for both
Both ship as freeze-dried powder, both mix with bacteriostatic water the same way, and both are stored at minus 20 C out of the light until then. What differs is which breakdown route each sequence is prone to, and the stability guide shows how to read that from the amino acids.
