IGF-1 LR3 Reconstitution & Dosage Calculator
This free IGF-1 LR3 calculator turns your vial size, the bacteriostatic water you add, and your target amount into a concentration, a draw volume, and the exact units on a U-100 insulin syringe. IGF-1 LR3 is the smallest-vial compound on this site — supplied at a fraction of a milligram rather than 5 or 10 mg — so the arithmetic runs at a different scale from every other calculator here. This is a measurement tool — it does not recommend an amount.

Quick summary
- Converts a sub-milligram vial, bacteriostatic water (mL), and a microgram amount into concentration, draw volume, and U-100 units.
- Built for the 0.1 mg (100 mcg) vial size, where the whole vial is smaller than a single draw of most peptides.
- Educational research and measurement tool only — it does not diagnose, treat, or recommend an amount.
What this IGF-1 LR3 calculator does
This calculator does one job well: it turns your vial size, the amount of bacteriostatic water you add, and your target amount into a concentration (mg/mL), a draw volume (mL), and the matching units on a U-100 insulin syringe. Change any input and the result updates instantly.
IGF-1 LR3 ships as a freeze-dried powder. Before it can be measured into a syringe it has to be reconstituted — dissolved in bacteriostatic water. How much water you add sets the concentration, and the concentration sets how many units each amount works out to. The presets above cover the most common IGF-1 LR3 vial setups; use the custom fields for anything else.
How to use the IGF-1 LR3 calculator
Pick your syringe
Choose the U-100 insulin syringe you'll draw with. Smaller syringes (0.3 mL / 30u) have finer lines, which helps when the draw is small.
Enter your vial and water
Set the milligrams in your IGF-1 LR3 vial and the bacteriostatic water you added. Together these set the concentration.
Set your target amount
Toggle mg or mcg and pick (or type) the amount you're measuring for. The calculator does the conversion for you.
Read the draw
The result panel shows concentration, draw volume, and the exact U-100 units to pull, plus how many doses your vial contains.
IGF-1 LR3 reconstitution math, explained
The math is short. Concentration = vial size ÷ bacteriostatic water. Draw volume = target amount ÷ concentration. Units = draw volume × 100 (a U-100 syringe reads 100 units per mL). The table below shows common IGF-1 LR3 setups and the units for a 20 mcg amount at each.
| Vial size | Bac water | Concentration | Units per 20 mcg |
|---|---|---|---|
| 0.1 mg | 0.5 mL | 0.2 mg/mL | 10 units |
| 0.1 mg | 1.0 mL | 0.1 mg/mL | 20 units |
| 0.1 mg | 2.0 mL | 0.05 mg/mL | 40 units |
| 1 mg | 1.0 mL | 1 mg/mL | 2 units |
| 1 mg | 2.0 mL | 0.5 mg/mL | 4 units |
IGF-1 LR3 amount-to-units reference
How common amounts convert to U-100 syringe units at two example concentrations. These are arithmetic conversions for reference, not a recommendation of any amount.
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 10 mcg (0.01 mg) | 0.1 mL | 10 units |
| 20 mcg (0.02 mg) | 0.2 mL | 20 units |
| 50 mcg (0.05 mg) | 0.5 mL | 50 units |
| 100 mcg (0.1 mg) | 1 mL | 100 units |
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 10 mcg (0.01 mg) | 0.2 mL | 20 units |
| 20 mcg (0.02 mg) | 0.4 mL | 40 units |
| 50 mcg (0.05 mg) | 1 mL | 100 units |
| 100 mcg (0.1 mg) | 2 mL | 200 units |
Mixing, color & storage tips
Read the vial label carefully
The single most common error with this compound is a scale mistake. A 0.1 mg vial holds 100 mcg in total — one hundredth of a 10 mg peptide vial. Entering 0.1 where the tool expects milligrams is correct; entering 100 because the label also says 100 mcg will overstate the vial by a thousandfold. The unit toggle exists to make this unambiguous.
The whole vial is one or a few draws
Because the vial total is 100 mcg, a 20 mcg target uses a fifth of it. Reconstituting with 1 mL gives 100 mcg/mL, so 20 mcg is a clean 20 units — the arithmetic is unusually tidy at this concentration, which is why it is the common choice.
Mixing a tiny quantity of powder
There is very little solid in the vial and it can be hard to see. Add the water slowly against the inside wall, swirl gently, and inspect against the light to confirm it has dissolved. Do not shake.
Storage
IGF-1 LR3 is less robust than a short peptide. Keep the dry powder cold and dark, refrigerate once reconstituted, protect it from light, and plan around a limited usable window. Do not freeze a mixed vial.

IGF-1 LR3 — frequently asked questions
What does this IGF-1 LR3 calculator tell me?
It converts your vial size, bacteriostatic water volume, and target amount into concentration in mg/mL, draw volume in mL, and the matching units on a U-100 insulin syringe. It is a measurement tool, not a recommendation.
Is the IGF-1 LR3 calculator free?
Yes — free, browser-based, and no account is required.
How much bacteriostatic water do I add to a 0.1 mg IGF-1 LR3 vial?
1 mL is the common choice because it makes the arithmetic clean: 0.1 mg in 1 mL is 100 mcg/mL, so every 1 mcg is 1 unit on a U-100 syringe. 2 mL halves that to 50 mcg/mL, so each microgram becomes 2 units.
How many units is 20 mcg of IGF-1 LR3?
At 100 mcg/mL (0.1 mg + 1 mL) it is 20 units (0.2 mL). At 50 mcg/mL (0.1 mg + 2 mL) it is 40 units. Units always depend on your exact concentration.
Why is the IGF-1 LR3 vial so much smaller than other peptide vials?
Because it is active at far lower amounts. A 0.1 mg vial is a normal supply size for this compound, where 5 or 10 mg is normal for something like BPC-157. The formula is the same; only the scale changes.
How long does a reconstituted IGF-1 LR3 vial last?
Refrigerate it, keep it dark, and plan around a limited usable window — it is less stable in solution than short peptides. Do not freeze a mixed vial.

IGF-1 LR3 protocol & evidence
There is no established human dosing schedule for IGF-1 LR3 — the published work is animal or cell-culture research. The protocol page explains what that work does and does not show.
