IGF-1 LR3 (Long R3 IGF-1) is Certified Aminos' research listing for an engineered analogue of insulin-like growth factor 1, modified with an arginine substitution at position 3 and a 13-residue N-terminal extension. This is a distinct molecule from both native IGF-1 and from mecasermin, the FDA-approved recombinant IGF-1 in INCRELEX. Available in 1mg for laboratory research use only.

Each order ships as an IGF-1 LR3 research peptide in a 1mg vial, manufactured for laboratory use only.
| Compound | IGF-1 LR3 (Long R3 IGF-1) |
|---|---|
| Structural Modification | Glu3→Arg substitution plus a 13-residue N-terminal extension relative to native 70-residue IGF-1 -- confirmed by solution-structure NMR |
| Related Compound Distinction | Not mecasermin (INCRELEX), the FDA-approved, amino-acid-identical-to-native recombinant IGF-1. IGF-1 LR3 is a structurally distinct analogue with no FDA approval of its own; mecasermin's approval does not extend to it |
| CAS Number / Molecular Weight | Not stated on this listing -- not independently confirmed |
| Available Size | 1mg |
| Purity | Not independently verified -- no batch-specific COA is currently published |
| Identity | Not independently confirmed by mass spectrometry or an equivalent method |
| Intended Use | Laboratory research only (RUO) |
When your order arrives, match the lot number printed on the vial to the lot number on the COA before beginning any work. Until a batch-specific COA is published for this product, treat any purity or identity figure shown elsewhere on this listing as a supplier claim, not an independently verified result.
No peer-reviewed human study of IGF-1 LR3 exists — a 2026 literature review placed it in its lowest evidence tier. Here's what the cell and animal research actually shows, and where it stops.
HCG and LH bind the exact same receptor — yet research shows they send measurably different signals once they do. Here's what's actually established about HCG's structure, mechanism, and the FDA's position on HCG weight-loss claims.
BPC-157 sits in a different WADA category than TB-500 or ipamorelin — and that difference actually matters if you're trying to understand the rules. Here's the 2026 list, compound by compound, with the official source for each.
