What is IGF-1 LR3?

IGF-1 LR3 is a long-acting analog of insulin-like growth factor 1, engineered to resist the binding proteins that normally switch it off, so it stays active far longer. IGF-1 is a primary driver of cell growth and tissue repair — which is exactly why this is a higher-intensity research compound that demands veterinary oversight.

Everything here is research context to bring to your veterinarian — not a treatment claim, and not dosing advice.

What is IGF-1 LR3 studied for in pets?

A long-acting IGF-1 analog studied for cell growth and muscle/tissue recovery. A higher-intensity research compound — always vet-guided.

How IGF-1 LR3 is used

Studied in: Horses · Dogs (research-stage).

Quality & third-party testing — what to look for

The single most important thing when sourcing any research peptide is knowing exactly what's in the vial. Here's the standard to hold any seller to:

  • Third-party (HPLC) testing with a Certificate of Analysis (COA) confirming identity and purity — ask for it before you buy.
  • Handled and labeled as a research-grade compound, not marketed as a mass-market supplement.
  • Not FDA-approved for pets — used off-label, under veterinary guidance, never as a treatment claim.
