IGF-1 Handling Guide: Common Mistakes to Avoid
Most handling advice for research peptides is written generically. The practices below are the ones that specifically matter for IGF-1 — including the mistakes it is unusually easy to make with this compound.
Overview
Acidic liquid first, carrier protein and low-bind tubes to stop it sticking, and single-use portions. Never re-freeze.
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.

Bench practices for IGF-1
- Dissolve first in dilute acetic acid, then dilute into the working buffer — never expect plain water to take it up fully.
- Use a carrier protein and low-bind labware to prevent adsorptive loss.
- Aliquot for single use; do not re-freeze reconstituted protein.
The chemistry behind these practices
- Misfolding and irreversible denaturation — the dominant failure mode.
- Aggregation of unfolded protein.
- Adsorptive loss to surfaces without a carrier protein.
Storage summary
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.
