IGF-1 LR3

Engineered IGF-1 that lasts 20–30× longer than the native peptide.

  • 20–30 hour half-life against native IGF-1's minutes
  • Fires PI3K/Akt/mTOR directly, skipping the GH axis
  • The usual downstream-amplification partner in GH-axis stacks

Why researchers choose it

IGF-1 LR3 is a modified IGF-1 analog built to stay in circulation roughly 20 to 30 times longer than the native molecule. It binds IGF-1R directly and lights up the PI3K/Akt/mTOR pathway, the core route to protein synthesis and cellular repair. Worth saying plainly: no form of LR3 is FDA-approved and there is no human dosing data behind it.

Reconstitution reference concentration only, not dosing

Set the vial strength and how much bacteriostatic water you draw into it. This returns the resulting concentration for lab handling. It is a dilution reference, not a dosing recommendation.

Most compounds reconstitute with bacteriostatic water; a few acid-loving peptides use acetic acid instead. How much to draw, and how many vials a cycle needs, live in the Complete Peptide Guide, not here.

How much, and how many vials for a full cycle?

Protocol and cycle-length questions get answered in the Complete Peptide Guide, not here. These listings carry no dosing.

  • Built for staying power: LR3 persists roughly 20 to 30 times longer than native IGF-1, with a 20 to 30 hour half-life.researchdosing
  • Binds IGF-1R with high affinity and activates PI3K/Akt/mTOR, the central protein-synthesis cascade.PubMed: IGF-1 LR3
  • Signals directly at the receptor, bypassing the GH axis.peptidedosages
  • Honest framing: LR3 is not FDA-approved in any form (mecasermin is a different molecule) and carries no human dosing data, so the entire evidence base is preclinical.PubMed: IGF-1 LR3
  • Growth-signal caution runs both ways in the literature: breast, ovarian, or uterine history in female models, prostate signal in male models.thepeptidereport
