IGF-1 LR3 (Long R3 IGF-I) is a laboratory-made analogue of human insulin-like growth factor-1, designed in Adelaide in the early 1990s to bind poorly to the proteins that normally hold IGF-1 in check. It is used as a laboratory reagent and has been studied in rats, mice, pigs and other animals, but we found no published human trials, and it is not an approved medicine. Read the full IGF-1 LR3 guide, with the published research and references.

Price per mg is only half the comparison. Check that the supplier publishes a certificate of analysis for the batch it is selling, ideally from an independent laboratory, and that the certificate confirms identity as well as purity: our guide on how to read a COA shows what to look for. A price far below the rest of the list is more often a warning than a bargain; peptide prices explained sets out why.
For what IGF-1 LR3 is and what published studies have found, see our IGF-1 LR3 guide. Handling questions are covered in how to store peptides, and the peptide calculator converts a vial size and water volume into concentration and syringe units. Rules on buying and importing differ by country: read are peptides legal in Europe? and see all suppliers serving Europe.
How to spot a fake peptide supplier explains each of these in more detail, and third-party peptide testing covers what independent results can and cannot prove.
Most research peptides are sold as freeze-dried (lyophilised) powder in sealed vials, which is mixed with a diluent such as bacteriostatic water before use in the lab. Some suppliers also sell pre-mixed solutions, nasal sprays or capsules under the same name. These are different products with different stability and dosing, so compare price per mg only between the same form, and check which form a listing is before comparing it with the rest of the table.
19 of the suppliers PepFinder tracks list IGF-1 LR3 and are based in or ship to Europe. The highest rated are New-U Research Compounds, Research Peptides NI, Power Peptides. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews; nobody pays to be included or to rank higher.
Listed prices in USD run from US$36.10/mg to US$249.90/mg, median US$96.19/mg, across 7 listings from 5 suppliers. Compare price per mg rather than price per vial, and only within one currency; a price far below the rest is more often a warning than a bargain.
Suppliers on this page list IGF-1 LR3 in 0.1mg / Standard Vial, 0.1mg / Research Pen, 0.1mg / Pen Refill, 0.1 mg, Kit = 0.1mg vial, bac water, syringes, 0.1mg Vial. Most research peptides are sold as freeze-dried powder in sealed vials; capsules, sprays and pre-mixed solutions are different products, so compare price per mg only between the same form.
Across the EU, Iceland, Liechtenstein, Norway and Switzerland, a peptide that counts as a medicine cannot be placed on the market without an authorisation, and peptides sold as research products have none; penalties, possession rules and doping laws are set by each country and differ. Our page on whether peptides are legal in Europe sets out the rules with a link to every source. This is general information, not legal advice.
Personal import rules are set nationally and differ widely: for example, Norway stops medicines sent by post, Austria says importing unauthorised peptide products is prohibited, and Switzerland allows one month's supply of a medicine for your own use but takes a zero-tolerance approach to doping substances. Each supplier on this page shows where it is based, so you can see whether an order would cross a border.
Ask for a certificate of analysis for the batch being sold, and check that it names the laboratory, the batch number and the test date, and that it confirms identity by mass spectrometry as well as purity by HPLC. PepFinder has not yet collected certificates for IGF-1 LR3 from these suppliers, so check each supplier's own site.
How this list is built: suppliers appear because they list IGF-1 LR3 on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder Score. Prices, sizes and stock are as each site listed them when checked and may have changed. Provisional scores are based on incomplete research.
