Overview
IGF-1 LR3 is a modified insulin-like growth factor 1 with an extra 13 amino acids and one substitution, which stop it binding to IGF binding proteins so it stays active much longer.
This listing is Vita Science IGF-1 LR3 1 mg (1 mg), photographed as we ship it and priced in Canadian dollars.
How it works
It activates IGF-1 receptors directly, promoting cell growth and glucose uptake. It is mainly used in cell-culture research.
Clinical reference
There is no approved human dose. A different drug, mecasermin, is approved for rare growth disorders.
Reference information from product labels and clinical literature only. It is not a recommendation or dosing advice for you; any use should be set and monitored by a doctor.
Measuring calculator
Type the amount from your prescription or clinician; the calculator only converts it. It does not suggest how much to take.
Vial contains 1 mg. U-100 insulin syringes have 100 units per ml.
Combinations and interactions
- Can cause low blood sugar; dangerous with insulin or other glucose-lowering drugs.
Risks and side effects
- Limited human data. Most research peptides have not been through full clinical trials, so long-term effects are unknown.
- Sterility. Freeze-dried peptides must be reconstituted with sterile technique; contamination can cause abscesses.
- Low blood sugar. Hypoglycaemia is the main acute risk.
- Growth signalling. Not suitable for anyone with cancer.
Do not use it if you have diabetes, active cancer, or are pregnant.

IGF-1 LR3 1 mg is a freeze-dried powder. After it is mixed with bacteriostatic water it is normally injected under the skin with a short insulin needle. These are the three standard subcutaneous areas; rotate between them. Finding it. Anywhere on the belly at least 5 cm from the navel, away from scars and the waistband. Pinch a fold and inject into it. Why it is used. The most fat, steady absorption and easy to see. Watch for. Move each injection a few centimetres from the last to prevent lumps. Nursing reference volume: Up to about 1 ml Finding it. The middle of the front of the thigh, a hand-width below the hip and above the knee. Why it is used. Easy to reach and a good rotation partner for the belly. Watch for. Absorption can be a little slower than the abdomen. Nursing reference volume: Up to about 1 ml Finding it. Halfway between shoulder and elbow on the back of the arm. Why it is used. Adds a third area to rotate through. Watch for. Hard to reach on yourself; a helper is useful. Nursing reference volume: Up to about 1 ml Every time: wash your hands, swab the stopper and skin with alcohol, use a new sterile needle and syringe and never share. See a doctor for spreading redness, heat, swelling, fever or numbness. This is general reference information from standard injection guidance, not medical advice.
