Free Peptide-Specific Calculator – BPC-157, TB-500, Ipamorelin, CJC-1295, GHK-Cu & More
Select any popular research peptide below and the calculator instantly loads typical vial sizes, common bacteriostatic water volumes and frequently discussed research doses. You can still edit every field. The tool then returns exact concentration, draw volume and U-100 insulin syringe units for that specific compound.

Peptide quick-reference guides
The summaries below reflect commonly discussed research practices only. They are educational reference points, not recommendations.
BPC-157
Most research vials contain 5 mg. Typical reconstitution uses 1–2 mL bacteriostatic water (2 mL → 2.5 mg/mL). Frequently referenced research doses fall between 250 mcg and 500 mcg. A 250 mcg dose from a 5 mg + 2 mL vial is 10 units on a U-100 syringe.
TB-500 (Thymosin Beta-4 fragment)
Common vial sizes are 5 mg and 10 mg. Researchers often reconstitute with 2–3 mL water. Doses discussed in research contexts are frequently in the 2–5 mg range (2000–5000 mcg). Higher milligram doses produce larger unit draws unless concentration is increased.
Ipamorelin
Standard research vials are usually 5 mg. Reconstitution with 2–2.5 mL BAC water is common. Typical research dose range cited is 200–300 mcg. At 5 mg + 2 mL the concentration is 2.5 mg/mL, so 200 mcg = 8 units.
CJC-1295 (no DAC / Mod GRF 1-29)
Often supplied as 2 mg vials. Reconstitution with 1–2 mL water is typical. Research doses commonly fall between 100–200 mcg. Because the vial is smaller, concentration and unit numbers change quickly with water volume.
GHK-Cu
Research vials frequently contain 50 mg or 100 mg because doses are higher. Reconstitution volumes of 2–5 mL are common. Individual research doses are often discussed in the 1–2 mg range. The calculator handles these larger milligram amounts without conversion errors.
MOTS-c
Typical research vials are 10 mg or 40 mg. Reconstitution and dosing vary widely in published discussions. The calculator lets you set any combination of vial size, water and target dose for precise unit conversion.
KPV
Commonly available as 5 mg or 10 mg vials. Research doses are often in the 200–500 mcg range. Standard 2 mL reconstitution of a 5 mg vial yields the familiar 2.5 mg/mL concentration.
Epithalon (Epitalon)
Research vials are frequently 10 mg. Doses discussed in literature are often 5–10 mg per administration, which produces larger syringe volumes unless higher concentrations are prepared.
How the peptide-specific calculator works
Regardless of which peptide you select, the underlying arithmetic remains the same:
Concentration (mcg/mL) = Concentration (mg/mL) × 1000
Draw volume (mL) = Desired dose (mcg) ÷ Concentration (mcg/mL)
Units (U-100) = Draw volume (mL) × 100
Doses per vial = (Vial size in mcg) ÷ Desired dose (mcg)
The advantage of the peptide-specific interface is that typical starting values are pre-loaded, reducing the chance of entering an unrealistic vial size or dose for that compound. You can still override every number.
Worked examples by peptide
Concentration = 2.5 mg/mL (2500 mcg/mL)
Volume = 250 ÷ 2500 = 0.1 mL
Units = 10
Doses per vial = 20
Concentration = 2.5 mg/mL
Volume = 200 ÷ 2500 = 0.08 mL
Units = 8
Doses per vial = 25
Concentration = 3.333 mg/mL
Volume = 2000 ÷ 3333 ≈ 0.60 mL
Units ≈ 60
Doses per vial = 5
Concentration ≈ 16.67 mg/mL
Volume = 1500 ÷ 16667 ≈ 0.09 mL
Units ≈ 9
Doses per vial ≈ 33
Why peptide-specific tools matter
Generic calculators treat every compound the same. In practice, vial sizes, potency and typical research doses differ dramatically between a 5 mg healing peptide and a 50 mg copper peptide or a multi-milligram metabolic compound. Pre-loading realistic defaults reduces arithmetic mistakes and helps researchers quickly confirm that a planned reconstitution will produce measurable, practical unit marks on an insulin syringe.
General reconstitution reminders (all peptides)
- Always use bacteriostatic water for multi-dose vials.
- Inject water slowly down the side of the vial; never spray directly onto the powder.
- Swirl gently — do not shake.
- Label the vial with peptide name, concentration, and reconstitution date.
- Store reconstituted solutions refrigerated (2–8 °C) and protected from light.
- Most research peptides remain stable approximately 28 days after reconstitution under proper conditions.
