What to Check When Your IGF-1 Arrives
Not every irregularity on arrival is a defect, and not every compound is defective under the same conditions. Here is what actually matters when a IGF-1 shipment arrives.
Overview
Cold-chain condition matters much more than for short peptides, and damage may be invisible — keep the paperwork as much as the vial.
What IGF-1 actually is
The natural growth factor the body produces after growth hormone acts — a folded protein, not a simple peptide, studied for muscle and tissue signalling. This is the native form, different from the longer-acting LR3 version.
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.

Arrival inspection for IGF-1
Cold-chain condition matters far more than for short peptides. A folded protein that has been through uncontrolled temperature excursions may look and weigh exactly the same while being compromised — inspect documentation as much as the vial.
Storage on arrival
Documentation to check
Confirm the mass near 7649 Da, but treat a folding/bioidentity result as the figure that actually matters — a high purity percentage does not establish correct folding.
What IGF-1 is studied for
Studied as the native ligand for the IGF-1 receptor and its downstream proliferation and survival pathways.
Examined in muscle research models for its role in satellite-cell behaviour and anabolic signalling.
Compared with IGF-1 LR3, whose reduced binding-protein affinity gives a longer active window — a contrast studied directly in the literature.
