IGF-1
Native insulin-like growth factor studied for muscle, tissue signalling, and cellular-proliferation research.
Molecular reference
Research background
IGF-1 (Insulin-like Growth Factor-1) is the growth-factor peptide at the centre of muscle, recovery, and tissue-signalling research. It is the natural messenger the body produces after growth hormone does its work, carrying that signal into cells to drive proliferation and repair. This is the native form — distinct from the longer-acting LR3 analogue — studied for satellite-cell activation and anabolic signalling in research models.
As a foundational growth-factor tool, native IGF-1 lets researchers study the downstream signal directly rather than the hormone that triggers it.

Reconstitution
- Supplied as a lyophilized (freeze-dried) powder for laboratory reconstitution.
- Bacteriostatic water (0.9% benzyl alcohol) is the most common reconstitution solvent for multi-use research handling; sterile or acetic-acid solutions are used for specific compounds.
- Introduce solvent slowly against the vial wall rather than directly onto the powder, and allow it to dissolve without vigorous shaking.
- Use the reconstitution calculator to determine solvent volume for a target concentration in your protocol.
Storage & handling
- Lyophilized powder: store sealed at -20 °C for long-term stability; short periods at 2–8 °C are generally acceptable.
- Once reconstituted: refrigerate at 2–8 °C and protect from light; use within the compound-specific window noted on the COA.
- Avoid repeated freeze–thaw cycles of reconstituted solution.
- Keep away from direct light and heat at all times.
Purity & verification
Every Popular Peptides batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity).
