|---|---|---|
| Category | Growth Hormone / IGF-1 Axis | Recovery |
| Research Stage | Preclinical | Phase 2 |
| Mechanism of Action | IGF-1 Receptor Signaling IGF-1 LR3 binds the IGF-1 receptor (IGF1R) - a transmembrane receptor tyrosine kinase expressed on virtually every cell type in the human body. IGF1R activation triggers two principal intracellular signaling cascades: PI3K / Akt / mTOR… | ARA-290's mechanism of action is one of the more elegantly engineered examples of pharmaceutical design in the peptide space.

Frequently asked
What's the difference between IGF-1 LR3 and ARA-290?
IGF-1 LR3 is a growth hormone / igf-1 axis that igf-1 receptor signaling igf-1 lr3 binds the igf-1 receptor (igf1r) - a transmembrane receptor tyrosine kinase expressed on virtually every cell type in the human body. igf1r…. ARA-290 is a recovery that ara-290's mechanism of action is one of the more elegantly engineered examples of pharmaceutical design in the peptide space. understanding it requires appreciation of the…. The two differ in mechanism, half-life (20-30 hours (community/vendor estimate; no published human PK study of IGF-1 LR3) vs ~12 minutes for native IGF-1 vs ~2 minutes (plasma half-life; downstream tissue-protective effects persist hours to days)), and typical dose range.
Which has the longer half-life, IGF-1 LR3 or ARA-290?
IGF-1 LR3 has a half-life of 20-30 hours (community/vendor estimate; no published human PK study of IGF-1 LR3) vs ~12 minutes for native IGF-1. ARA-290 has a half-life of ~2 minutes (plasma half-life; downstream tissue-protective effects persist hours to days). Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
Which is cheaper, IGF-1 LR3 or ARA-290?
Lowest listed price on BodyHackGuide: IGF-1 LR3 from $49.99, ARA-290 from $32.00. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers.
Can you stack IGF-1 LR3 and ARA-290?
Stacking depends on mechanism overlap, safety profile, and goals. IGF-1 LR3 and ARA-290 should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds.
