IGF-1 LR3
Long R3 IGF-1
Third-party tested · certificate on file · hormones
Eighty-three residues, which makes it the longest chain we stock and a different proposition from the short peptides around it. Recombinant rather than solid-phase, sold by the milligram, and shipped with the same two assays as everything else.

What the price already covers
- A certificate of analysis for the exact lot in the box, not a specimen from a previous one.
- Purity by reversed-phase HPLC and identity by mass spectrometry, on every lot.
- A second assay at an independent laboratory, drawn from the lot that ships to you, at our cost.
- Net peptide content measured rather than assumed, so the reconstitution maths is right.
- The manufacturing facility named on the record, and named again if we stop buying from it.
Free shipping over $99, out the door by 2pm ET, and 60 days to send an unopened vial back for a full refund.

Eighty-three residues: an arginine at position three and a thirteen-residue N-terminal extension. The longest chain in the catalog, which is why it is sold by the milligram.
