IGF-1 LR3
IGF-1 LR3 is supplied by White Label Peptides as a lyophilised powder in multi-dose vials, for laboratory and research use, to business buyers only. It sits in our performance category. Every batch is verified by HPLC and ships with its own Certificate of Analysis.
What varies by batch
The page identifies the compound. The certificate records the batch.
Purity, method, analysis date and issuing party belong on the batch record rather than in page copy.
Specification
Compound data
The specification below is the batch-independent data. Purity and analysis date vary by batch, so they appear on the certificate issued with your order rather than on this page.

What this compound is
IGF-1 LR3 in supply terms
IGF-1 LR3 (Long R3-IGF-1, CAS 946870-92-4) is a synthetic analogue of insulin-like growth factor 1, built as an 83-amino-acid recombinant protein with a molecular formula of C400H625N111O115S9 and a molecular weight of approximately 9117.6 g/mol. The analogue differs from native IGF-1, a 70-amino-acid protein, in two defined ways: an arginine residue in place of glutamic acid at position 3, and a 13-amino-acid extension added to the N-terminus. These two modifications account for the full difference between the 70-residue native sequence and the 83-residue analogue carried in this catalogue, and they are reflected directly in the higher molecular weight quoted above. Buyers comparing suppliers' technical sheets for this item should check that the quoted sequence length, substitution and molecular weight match this specification, since a shorter or unmodified IGF-1 listing is a different product. IGF-1 LR3 is supplied at >=98% purity (HPLC-verified, batch by batch) as a white to off-white lyophilised powder in multi-dose research vials, listed at a 1mg dosage strength. Reconstitute using bacteriostatic water or sterile laboratory-grade water. Store refrigerated at 2-8C in a cool, dry environment away from direct light; long-term storage prior to reconstitution should be under freezing conditions, confirmed on the Certificate of Analysis supplied with each order.

Questions
Supply, answered
Is IGF-1 LR3 available for private label?
Yes. It can be supplied under your own brand on the vial and the carton, with the Certificate of Analysis issued under your product name.
What is the minimum order quantity?
Set for this compound specifically and confirmed at the enquiry stage, before you commit.
What purity is supplied?
98 percent or higher, verified by HPLC. The certificate issued with your batch carries the actual figure for that batch.
How is it shipped?
As lyophilised powder in multi-dose vials, packed for transit. Schengen delivery in 2 to 5 days once the batch is released.
We already buy IGF-1 LR3. Can you quote against our current volume?
Yes. Send the volume and the delivery country. Pricing is tiered per compound, so the quote reflects what you buy rather than a list price.
Can you supply IGF-1 LR3 as a second source?
Yes. Terms are agreed per compound, so you can add IGF-1 LR3 without moving anything else you buy elsewhere.
