Acetyl Decapeptide-3
Also known as —
An acetylated decapeptide described as an IGF-1 mimetic, with limited independent characterisation of its receptor pharmacology.
- Length
- 10 amino acids
- Half-life
- Not well characterised
- Mechanism
- This peptide is described in supplier literature as an insulin-like growth factor 1 (IGF-1)-mimetic research ingredient. Direct agonism at the IGF-1 receptor, including binding affinity and receptor selectivity, should not be assumed without compound-specific experimental evidence.
- Studied in
- Exploratory skin-cell research examines fibroblast proliferation, extracellular-matrix markers and growth-factor-associated signalling in cultured cells.
About Acetyl Decapeptide-3
Acetyl Decapeptide-3 contains ten amino acid residues and an N-terminal acetyl group. It appears in cosmetic peptide literature as a synthetic growth-factor-mimetic ingredient, commonly associated with IGF-1. The ingredient designation does not establish that its sequence is a contiguous fragment of native IGF-1. Public independent accounts of its original design and structural validation are limited, so sequence origin, terminal chemistry and stereochemistry require confirmation against the supplier's primary technical documentation.
IGF-1 receptor activation normally involves receptor tyrosine phosphorylation and downstream pathways including PI3K–AKT and RAS–ERK. These pathways provide useful experimental endpoints when evaluating a proposed mimetic, but they are shared by many signalling systems. Fibroblast proliferation or altered matrix-marker expression cannot independently identify the receptor involved. Research-only studies should distinguish a phenotypic resemblance to IGF-1 signalling from demonstrated receptor engagement through phosphorylation assays, receptor perturbation and suitable growth-factor controls.
Laboratory notes
- Check whether the supplied material is isolated peptide or a formulated ingredient mixture before calculating assay concentrations.
- Document serum and growth-factor conditions, as background signalling can obscure peptide-associated changes in AKT or ERK phosphorylation.
- Verify sequence identity and acetylation by appropriate analytical methods; chromatographic purity alone does not establish identity.

Questions about Acetyl Decapeptide-3
Is Acetyl Decapeptide-3 the same molecule as IGF-1?
No. It is a ten-residue acetylated peptide, whereas mature IGF-1 is a 70-residue protein with three disulphide bonds.
Does an increase in AKT phosphorylation prove IGF-1 receptor activation?
No. Multiple receptors and cellular processes activate AKT. Receptor phosphorylation and receptor-specific perturbation provide more discriminating evidence.
Is its sequence necessarily derived directly from IGF-1?
No. The description 'mimetic' does not establish sequence homology or a contiguous sequence origin. That requires a verified sequence and supporting design documentation.
Is Acetyl Decapeptide-3 for human use?
No. It is supplied strictly for in-vitro laboratory research and is not for human or animal consumption.
