IGF-1 LR3 100mcg offers

research market · not for human use

These vendors sell compounds as research chemicals. Most are not FDA-approved.

No vendor we track lists IGF-1 LR3 100mcg right now. Other sizes are listed above.

Prices are each vendor’s listed price before shipping, unless a verified code is marked as included. Some outbound links are affiliate links and PeptideTech keeps a fee from sellers on checkout orders; neither affects grades or scores, or order apart from the labelled featured partner. PeptideTech does not test products. Certificates of analysis are the seller’s or the lab’s documents, attributed to them, and PeptideTech does not verify them unless a specific record says so.

Is IGF-1 LR3 FDA approved?
A product-specific regulatory review has not been completed. This catalogue entry does not establish authorization, lawful sale or import eligibility in any country; check the exact product and destination with the relevant regulator. Every listing on this page is a research-use-only product, whatever the status of any approved medicine with the same active compound.
Has IGF-1 LR3 been tested in clinical trials?
No ClinicalTrials.gov registration listing Long R3 IGF-I as an intervention was matched (checked October 1, 2026). This is a gap in matched records, not proof that no study exists. The selected PubMed records for Long R3 IGF-I are laboratory, animal or review publications; none is a human study in which participants received it. The listings compared here are research-use-only products sold for laboratory research, not medicines for human use.
Is IGF-1 LR3 legal to buy?
A research-labelled listing does not establish legal eligibility in every jurisdiction. Product status, purpose, import rules and destination matter. Review the jurisdiction-specific sources in the reference notes; PeptideTech does not provide a worldwide legality determination.
Can you buy IGF-1 over the counter?
PeptideTech has not completed a product-specific regulatory review for IGF-1 LR3, so this page does not state its prescription status. The listings compared here are research-use-only products sold for laboratory research, not medicines for human use. Whether a product may be bought, imported or used depends on the jurisdiction, the exact product and its purpose; PeptideTech does not sell products or provide a legality determination.
Is IGF a steroid?
No. IGF-1 LR3 is catalogued as a peptide, a chain of amino acids, not a steroid. Its exact sequence is not resolved to a public chemical record here, so check the supplier’s specification. The listings compared here are research-use-only products sold for laboratory research, not medicines for human use.
Where can I buy an IGF-1 LR3?
4 vendors have a current in-stock price for IGF-1 LR3 1mg, cheapest first: LA Peptides ($59.99), Amino USA ($70.00), Cenexa Labs ($78.99) and Nova Peptide Supply ($79.99). This list is ordered by displayed price only. PeptideTech may earn a commission on outbound links, and its featured partner, LA Peptides, is pinned first in the price table. The listings compared here are research-use-only products sold for laboratory research, not medicines for human use.
