IGF-1 LR3 1mg

Description

Each IGF-1 LR3 1mg vial at Sports Technology Labs contains 1mg of IGF-1 LR3, lyophilized and sealed. In short, it’s an IGF-1 analog. It’s sold for laboratory research only.

IGF-1 LR3 at a glance

IGF-1 LR3 is an 83-amino-acid analog of IGF-1 with an arginine swap at position 3 and a 13-amino-acid extension. Those changes stop it binding IGF binding proteins, so it stays active much longer.

It’s widely used in cell culture media.

The mechanism behind IGF-1 LR3

IGF-1 is the hormone that carries out much of growth hormone’s effect on cells. Most of it in the body is bound by IGF binding proteins, which hold it inactive.

LR3 has an arginine in place of glutamate at position 3 plus a 13-residue extension. Binding proteins barely recognize it, so it stays free and active far longer. That’s why it’s the standard IGF-1 in cell culture media.

What the literature says about IGF-1 LR3

It was developed for cell culture in the 1990s.

In cell culture it’s several times more potent than IGF-1.

IGF-1 LR3 compared with similar compounds

IGF-1 LR3 is a long-acting IGF-1 analog that IGF binding proteins barely hold. Here’s how the nearest options in our range differ:

• Tesamorelin is a stabilized GHRH analog with clinical trial data on abdominal fat
• Ipamorelin is the most selective ghrelin receptor agonist, releasing GH with little change in cortisol or prolactin
• Sermorelin is the first 29 amino acids of natural GHRH, broken down within minutes
• CJC-1295 DAC is a GHRH analog that binds albumin through its drug affinity complex and lasts for days
• GHRP-6 is a ghrelin receptor agonist known for a strong hunger signal alongside GH release

GHRH analogs and ghrelin receptor agonists act on two different pituitary receptors, which is why studies so often pair them. Compare them in our growth hormone peptides.

Reconstituting IGF-1 LR3 1mg

Working out the strength of your solution is one division: 1mg over the volume you add. Common volumes give these results:

• 1mL of diluent gives 1mg per mL
• 2mL of diluent gives 0.5mg per mL

Bacteriostatic water is the usual diluent, and it isn’t in the box. Add it along the glass wall, a little at a time, then swirl until the solution is clear.

Storing IGF-1 LR3 1mg

Before opening, IGF-1 LR3 1mg goes in the fridge at 2 to 8°C. The mixed solution stays refrigerated too and should be finished inside about 30 days. Don’t freeze it.

Keep mixed vials upright so the liquid doesn’t sit against the stopper.

How Sports Technology Labs tests IGF-1 LR3 1mg

Every batch is sent to MZ Biolabs in Tucson, Arizona, before it goes on sale. They run HPLC for purity and mass spectrometry to confirm identity. The latest certificates for this product read 98.63%.

The COA image is in the product gallery at the top of this page, so you can read the batch result before you order.

HPLC and mass spec answer different questions. HPLC tells you what share of the sample is the main compound. Mass spec tells you the compound is the right molecule. A COA with only one of them leaves a gap.

Orders are covered by a 60-day money-back guarantee.
