doses of IGF-1 LR3 used in research

No FDA or ex-US label and no registered human trial; the cited literature on Long-R3-IGF-I is animal and cell-culture work. These are the amounts specific labels and studies used, linked to each source. They are references, not recommendations; a prescription label takes priority.

what the numbers mean · where they come from

terms and sources

Label amount or measured amount. The calculator starts from the amount printed on the vial. A lot certificate’s measured content (net peptide content, in mg) can replace it for the vial that was tested. HPLC purity is a share of peak area, not a mass, so a purity-only correction is shown as an estimate. See HPLC, certificate of analysis and how to read a peptide COA.
Concentration. Amount in the vial ÷ water added. Terms: reconstitution, bacteriostatic water, lyophilized.
Syringe units. A volume: 0.01 mL per unit on a U-100 syringe, 0.025 mL on U-40. Units say nothing about the compound until the concentration is known.
Cost per draw. Vial price × amount per draw ÷ vial amount, from the price per mg of a current offer. Offers come from the IGF-1 LR3 price comparison; certificates from the COA library.

Arithmetic only, on the numbers entered. Amounts from labels or trials are cited references, not recommendations; PeptideTech does not give personal use instructions and does not test products.

short answers

IGF-1 LR3 calculator questions

How much bacteriostatic water do I add to IGF-1 LR3 1mg?

Any volume the vial holds; 1 mL gives 1 mg/mL, so 10 units on a U-100 syringe holds 100 mcg. More water makes each draw read more units. The table below shows 1–5 mL for every IGF-1 LR3 vial size on sale.

What changes the calculated concentration?

Only two inputs: the amount of IGF-1 LR3 in the vial and the water added. 1mg in 1 mL is 1 mg/mL; twice the water halves it, and the amount per draw then reads twice the units. A lot certificate's measured content replaces the label: LA Peptides's 1mg lot 1418 measured 1.24 mg, which in 1 mL is 1.24 mg/mL. HPLC purity is a share of peak area, not a measured mass, so it is shown only as an estimate.

What doses of IGF-1 LR3 were used in research?

No FDA or ex-US label and no registered human trial; the cited literature on Long-R3-IGF-I is animal and cell-culture work. PeptideTech does not list unsourced doses.

What does IGF-1 LR3 cost per mg?

The lowest current US price is $59.99 for 1mg at LA Peptides (about $59.99 per mg, checked 2026-11-03). The calculator turns any vial price into cost per draw.

How much IGF-1 LR3 is really in the vial?

Lot certificates on file report measured content: for example LA Peptides's 1mg lot 1418 measured 1.24 mg at 99.7% purity. Use the certificate correction to calculate from the measured amount.
