How to Store IGF-1 LR3: Temperature, Shelf Life & Handling
Storage requirements for IGF-1 LR3 follow from what the molecule actually is — recombinant 83-residue protein analogue of igf-1. The conditions below reflect that chemistry rather than generic peptide guidance.
In plain English
Freezer or colder for the powder, fridge for short-term use once mixed, one to two weeks. For longer storage, single-use portions are the standard approach, because thawing repeatedly damages it permanently.
What IGF-1 LR3 actually is
IGF-1 LR3 is a modified version of insulin-like growth factor 1, a natural growth signal. Two changes were made so that carrier proteins cannot grab and hold it. Crucially, it is a genuine folded protein rather than a simple chain — and that changes every handling rule.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Storage conditions for IGF-1 LR3
Why these conditions, specifically
Treat IGF-1 LR3 as a protein, not a peptide. Everything that makes short peptides forgiving — no fold to lose, no disulfides, no aggregation propensity — is absent here.
The main route to be aware of: denaturation and aggregation — the dominant failure mode, and one that has no equivalent in short unstructured peptides.

Single-use aliquots are the standard practice, and here it genuinely matters. IGF-1 LR3 has tertiary structure to lose — unlike the unstructured short peptides in this catalogue, it can denature, and denaturation is not reversible on rewarming.
What IGF-1 LR3 is studied for
The Arg3 substitution reduces binding-protein affinity, which is the entire design rationale.
Widely used in cell-culture research as a growth-factor supplement.
Studied in muscle-biology research models.
The canonical downstream pathway examined in IGF-1 receptor research.
