An extended-action insulin-like growth factor researched for its role in cellular growth and repair.
Researched for IGF-1 mediated repair pathways.
Studied for a prolonged active window.
Designed for focused, monitored study.
IGF-1 LR3 (Long R3 IGF-1) is a modified, long-acting form of insulin-like growth factor 1 — the main molecule through which growth hormone drives cell growth.
It is potent, evidence is largely preclinical, and it is supplied strictly for research use.
How it works: IGF-1 LR3 activates IGF-1 receptors to promote cell growth and division, with an extended half-life because the LR3 modification reduces binding to carrier proteins. It is studied for muscle growth and hyperplasia.
Researched to support: growth signalling, long acting, targeted research.
Quality: Lyophilised (freeze-dried) powder, supplied for research use only. Our manufacturers carry out their own batch testing; we do not independently verify those results or issue certificates of analysis, so we back every order with our purity guarantee instead.
Find your protocol →Reconstitute: Use bacteriostatic water. Add it slowly down the inside wall of the vial and let it dissolve for 10 to 15 minutes. Do not shake.
Administer: Subcutaneous, usually with an insulin syringe.
Dose example: A 5 mg vial reconstituted with 1 ml gives 0.5 mg per 0.1 ml (10 units on a U-100 insulin syringe).
Store: Keep the powder cool and dry. Once reconstituted, store at 2 to 8 °C and use within about 28 days.
These are research materials, not medical advice. Talk to your doctor before use.
In research use IGF-1 LR3 is handled as a subcutaneous injection, with care around blood sugar:
Describes dosing used in clinical research, provided as reference only — not a usage recommendation or medical advice. This is an investigational research compound.
Cell-growth research: Laboratory studies examined IGF-1 and its analogs for promoting cell growth, division and muscle hyperplasia; controlled human trials of LR3 are lacking.
Extended activity: The LR3 modification is studied for a longer active window than native IGF-1.
Status: Not an approved medicine; supplied strictly as a research peptide.
Provided as a scientific reference based on published clinical results — not medical advice, a usage recommendation, or a claim about the research product supplied by Novapep.
Digestive effects are the most common and usually ease with gradual titration. Scientific reference only, not usage instructions.
Delivery: FAN Courier, 24 to 48 hours across Romania. Dispatched within 1 to 2 business days.
Free shipping: On orders over 250 lei.
EU orders: Shipped from partner stock, typically within about 14 days.
Payment: Cash on delivery, card on delivery, or bank transfer.
Packaging: Discreet, kept cool after delivery.
Peptides are short chains of amino acids (2 to 50) that act as signalling molecules. Ours are supplied for laboratory research.
The vial contains lyophilised powder only. You also need bacteriostatic water, a sterile syringe, and a needle. We stock bacteriostatic water under Supplies.
Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve for 10 to 15 minutes. Do not shake.
Keep the powder cool and dry. After reconstitution, store at 2 to 8 °C and use within about 28 days.
Most are administered subcutaneously with an insulin syringe, for slow, steady absorption. A few formulations use other routes.
It varies by peptide and protocol. Some are researched over a few days, others over several weeks.
A prescription is not required, but we recommend speaking with your doctor, especially if you have a medical condition or take other medication.
Our manufacturers carry out their own batch testing, but we do not test independently and do not hold certificates of analysis — so we make no purity claim of our own. We back it with a guarantee instead: you are welcome to have a vial independently tested — contact us first so we agree the laboratory. If the result doesn’t match the label, we reimburse the cost of the test and either replace the product or refund it.
