A long-lasting lab version of IGF-1, the hormone growth hormone works through.
Not approved. A lab version of IGF-1 used mainly in cell culture. A different form of IGF-1, mecasermin, is approved for a rare growth disorder.
IGF-1 is the hormone that carries out much of growth hormone’s work. IGF-1 LR3 is a modified version with extra building blocks that make it last much longer. It was developed for growing cells in laboratories.
It acts on the same receptor as natural IGF-1, but blood proteins that normally hold IGF-1 in check barely bind it, so it stays active longer.

Follow the storage conditions supplied on the batch label and certificate.
Keep the material in its original, sealed packaging. Follow your laboratory’s handling procedures and the supplied product documentation.
Refer to the lot-specific expiry date and stability documentation. Shelf life should not be inferred from the product name alone.
For solvent compatibility or preparation specifications, request the manufacturer’s batch documentation. Research protocols should be established by qualified laboratory personnel.
Every product comes three ways. It's the same peptide and the same amounts; what changes is the packaging, what's included and the price. Start with the pen kit box, which has the reusable pen, then refill it with dual-chamber vials.

The freeze-dried peptide and the bacteriostatic (BAC) water sit in separate chambers, divided by a rubber stopper. They stay apart until the cartridge is used.
The pen kit box has the reusable pen body with a dual-chamber vial, 12 disposable needles and a booklet. The drive, dial and indicator window stay with the pen: when a cartridge is empty, fit a new dual-chamber vial.
Choose the vial if you already have bacteriostatic water and your own lab supplies. It's the lowest price for the same amount.
