IGF-1 LR3
IGF-1 LR3 is a engineered insulin-like growth factor analogue. It appears as lyophilised research vials, often labelled 0.1 mg or 1 mg. The labelled vial mass is an input for concentration arithmetic, not a recommended amount. This reference explains identity, units and record-keeping; it states no starting amount, maximum amount, schedule or progression.
What IGF-1 LR3 is
IGF-1 LR3 is described in chemical and research databases as a engineered insulin-like growth factor analogue. Alternate names include Long R3 IGF-I. Names alone are not enough to identify a vial, so a useful record also preserves the exact label, supplier, lot and physical format.
The molecular weight recorded for identity checks is 9,111.4 g/mol and the CAS registry number is 946870-92-4. These identifiers help distinguish similar names; they do not establish purity, suitability or equivalence between products.
Label mass and unit conversion
IGF-1 LR3 may be encountered as lyophilised research vials, often labelled 0.1 mg or 1 mg. A label such as 0.1 mg states total mass before dilution. Once a measured diluent volume is entered, concentration follows from mass divided by volume. The IGF-1 LR3 calculator performs that arithmetic on values the user supplies.
| Label mass | Same mass in mcg | What it means |
|---|---|---|
| 0.1 mg | 100 mcg | Total labelled mass before diluent |
| 1 mg | 1000 mcg | Total labelled mass before diluent |
The usual logging unit for this reference is mcg. Syringe markings are volume, not mass, so a unit figure becomes meaningful only when the vial concentration and syringe calibration are recorded beside it.
What an accurate record contains
- Exact compound name and every alias printed on the label.
- Labelled vial mass, diluent volume and calculated concentration.
- Supplier, batch or lot identifier, received date and reconstitution date.
- The user's own entered amount, stored separately from the syringe-volume conversion.
- A source link and date for any identity or regulatory statement copied into the record.
Keeping these fields together makes later arithmetic auditable. A bare syringe-unit number cannot be reconstructed without concentration, and a compound name without the original label cannot prove which material was recorded.
Sources and verification
Use the PubMed search to inspect published literature and the PubChem search for chemical identifiers. Database entries change, so verify the current record before relying on a number outside this arithmetic reference.
Frequently asked questions
Does this page recommend a IGF-1 LR3 dose?
No. It explains identity, packaging units and deterministic arithmetic only. Every target amount in a calculator is supplied by the user; the page provides no starting amount, maximum amount, schedule or progression.
What vial sizes are listed for IGF-1 LR3?
0.1 mg, 1 mg are included as common label references. A vial label is a packaging fact, not an instruction to use that amount.
Why record the CAS number for IGF-1 LR3?
CAS 946870-92-4 is an identity reference that helps separate similarly named substances. It does not prove purity, authenticity, approval or suitability of a specific product.
Why are syringe units not enough for a log?
Syringe units measure volume. Without the vial mass and diluent volume, the same syringe reading can represent different mass amounts, so the historical entry cannot be interpreted reliably.

Track IGF-1 LR3 without re-doing the maths
Enter the vial once — mass, diluent volume, lot, date — and every entry after that converts automatically between mcg, mL and syringe units, with the vial counting down as you log.
