Product overview
IGF-1 LR3 1 mg Research Material
IGF-1 LR3, also described in scientific literature as Long R3 IGF-I, is an analogue of insulin-like growth factor I. Published laboratory and preclinical studies have examined its structure, binding characteristics and activity in experimental models.
This Peptora product is supplied as lyophilized peptide material with a labelled quantity of 1 mg per vial. Elementrix reports a tested-sample quantity of 1.012 mg and a purity result of 99.278%.
Published studies listed below are provided strictly as scientific background. They do not establish that Peptora’s material is suitable for clinical use, and they are not instructions or recommendations for human or veterinary use.

Batch documentation
Traceable From Product to Certificate
The product, batch identifier and Elementrix report are presented together so researchers can review the applicable certificate before ordering.
- ✓ Batch-specific COA available online
- ✓ Direct Elementrix verification link
- ✓ Reported purity, identity and net content
Expanded third-party review
More Than a Purity Percentage
This certificate reports identity, measured quantity and endotoxin alongside purity, with each result marked compliant by Elementrix.
The Peptora testing difference
We Test Beyond Purity
A purity percentage is only one part of a meaningful batch review. For batch IGF0766, Elementrix also reports identity, measured quantity and endotoxin.

What the expanded panel covers
Purity and content
HPLC purity of 99.278% and a tested-sample quantity of 1.012 mg are reported against the certificate specifications.
Identity confirmation
LC-MS analysis is reported as confirming the identity of the material evaluated by Elementrix.
Endotoxin result
The certificate reports an endotoxin result below 0.0886 EU/mg against a specification of less than 2 EU/mg.
Analytical method
The certificate states that chemical analysis was performed by HPLC with UV detection coupled with mass spectrometry.
Identity confirmation
The reported identity result is IGF-1 LR3 and is marked compliant on Elementrix COA 268011.
Direct verification
Report COA 268011 can be checked through Elementrix so the certificate is not dependent on Peptora’s description alone.
