About:
A modified analogue of insulin-like growth factor 1 designed to reduce binding-protein affinity, used in cell culture research.
What does this peptide do?
Human evidence is limited or indirect. Research focuses on cell culture.
Cell culture research
An IGF-1 analogue used as a cell culture reagent.
Evidence grade
CHighest evidence grade among the graded claims: C. Grades reflect study strength, not benefit.
What are the benefits and side effects of this peptide
What research says it may help with
- IGF-1 itself has real biology: infusion increased organ growth in animal models.
- What we could not verify is anything specific to the LR3 analogue sold online, which appears in reviews of the non-approved performance market rather than in trials.
Who should avoid it
- People who are pregnant or breastfeeding
- Children and adolescents
- People with diabetes, since IGF-1 analogues can lower blood glucose
- Known hypersensitivity to the preparation
- Active or prior cancer, given IGF-1 signalling in tumour growth
See the safety section. Absence of a flag is not evidence of safety.
A grade reflects evidence strength, not a recommendation to use this compound; a strong grade can attach to a harmful effect.
How to store this peptide
Typically sold as a lyophilized powder. Reconstituted solutions are perishable, need refrigeration, and require clean handling to avoid contamination.
Lyophilized storage
Store at −20 °C, protected from light.
Reconstituted storage
Keep at 2–8 °C and use within a short period. For longer storage, aliquot and freeze at −20 °C.
Storage Handling
Avoid repeated freeze–thaw cycles. Let the vial reach room temperature before opening.
