How many mL of bacteriostatic water do I add to a peptide vial?

Most researchers add 1–2mL per standard 5mg vial. Less water produces a higher concentration with fewer units per injection. More water gives a lower concentration with more units. The right amount is whatever yields a practical, measurable dose on your syringe. The calculator pre-fills each peptide's standard volume.

How do I know how much water to put in my peptide?

Choose a volume that results in drawing between 5–50 units per injection on a U-100 syringe — a range that's easy to measure accurately. For low-dose peptides under 500mcg, 1–2mL typically works. For high-dose peptides like TB-500 at 2,500mcg, 2–3mL is more practical. Use the calculator to preview results before reconstituting.

What is the difference between bacteriostatic water and sterile water for peptides?

Bacteriostatic water contains 0.9% benzyl alcohol as a preservative, inhibiting bacterial growth and allowing safe multi-dose use for up to 28 days after opening. Sterile water has no preservative and is single-use only. For research peptide protocols involving repeated injections from one vial, bacteriostatic water is the correct choice.

How do I read an insulin syringe for peptide dosing?

On a U-100 syringe, 100 units = 1mL, so 1 unit = 0.01mL. Draw back the plunger until the rubber stopper's flat edge aligns with your target unit number. The syringe calculator diagram above shows exactly which line to draw to. For small doses, use a 0.3mL syringe (30 units maximum) for better precision.

What does it mean to reconstitute a peptide?

Reconstitution dissolves a lyophilised (freeze-dried) peptide powder into a liquid diluent, typically bacteriostatic water, to create an injectable solution. Peptides are shipped as dry powder for stability. Reconstituting produces a liquid at a known concentration that can be drawn into a syringe and injected. The concentration depends on how much water you add.

Can I use sterile water instead of bacteriostatic water?

Yes, but only for a single dose — use the reconstituted solution immediately and discard any remainder. Sterile water contains no antimicrobial preservative, so repeated-access vials risk bacterial contamination. For any research protocol requiring multiple injections from one vial over days or weeks, bacteriostatic water is the correct choice.

How many units should I draw for my peptide dose?

Units (U-100) = (desired dose in mcg ÷ concentration in mcg/mL) × 100. Example: 250mcg dose, concentration 2,500mcg/mL → 250 ÷ 2,500 × 100 = 10 units. The calculator above computes this instantly for any combination of peptide, vial size, water volume, and dose. It also adjusts the result for U-50 and U-40 syringe types.

What happens if I shake a peptide vial instead of swirling it?

Vigorous shaking subjects the peptide to mechanical shear forces and creates foam, both of which break the molecular bonds that define a peptide's 3D structure. Denatured peptides lose biological activity. Always swirl the vial gently in a slow circular motion until the powder dissolves. If foam forms, let the vial stand undisturbed for 5–10 minutes before using.

How do I reconstitute a 10mg peptide vial?

Add 2–4mL of bacteriostatic water slowly down the inner vial wall. With 2mL you get 5,000mcg/mL; with 4mL you get 2,500mcg/mL. Swirl gently until fully dissolved. Label with the date and concentration. Use the calculator above to preview how many units to draw for your dose before deciding on the water volume.

What syringe should I use for peptide injections?

Use a U-100 insulin syringe for subcutaneous peptide injections. The 0.3mL syringe is ideal for small doses (under 30 units) due to its fine 1-unit increments. The 0.5mL syringe handles most standard doses. The 1mL syringe is appropriate for larger GLP-1 doses. Always use a fresh syringe for each injection.

How to Calculate Peptide Reconstitution in 3 Steps

Reconstitution math uses one formula: divide the peptide mass by the water volume to get concentration, then divide your dose by that concentration to get injection volume.

Calculate concentration

Concentration (mcg/mL) = Vial size (mg) × 1,000 ÷ BAC water (mL)

Example: 5mg vial + 2mL BAC water = 5,000 mcg ÷ 2 mL = 2,500 mcg/mL

Calculate injection volume

Volume (mL) = Desired dose (mcg) ÷ Concentration (mcg/mL)

Example: 250mcg dose ÷ 2,500 mcg/mL = 0.1 mL

Convert to syringe units

Units (U-100) = Volume (mL) × 100

Example: 0.1 mL × 100 = 10 units — draw to the 10-unit line on a U-100 syringe

The formula at a glance

Units = (Dose in mcg ÷ (Vial mg × 1,000 ÷ BAC water mL)) × 100

BPC-157 example: (250 ÷ (5 × 1,000 ÷ 2)) × 100 = 10 units

What is concentration and why does it matter?

Concentration tells you how many micrograms of peptide are in each millilitre of solution. A higher concentration (less water) means you draw fewer units per dose, which some researchers prefer for subcutaneous injection comfort. A lower concentration (more water) is easier to measure precisely on a syringe. There is no universally correct concentration — use whatever results in a practical, measurable dose for your protocol.

How to Reconstitute Peptides: Step-by-Step Guide

Supplies needed

Lyophilised peptide vial
Bacteriostatic water (BAC water) — 30mL multi-dose vial
U-100 insulin syringes (for reconstitution and dosing)
Alcohol swabs (70% isopropyl)
Sharps disposal container
Permanent marker (for labelling)
Refrigerator

Gather and inspect

Check both vials for cracks, cloudiness in the BAC water, or discolouration. The peptide powder should be white or off-white. Wash hands thoroughly and work on a clean surface.

Swab the tops

Wipe the rubber septum of both the peptide vial and BAC water vial with a fresh alcohol swab. Allow to air-dry for 10–15 seconds before piercing — do not blow or fan dry.

Draw bacteriostatic water

Using a fresh syringe, draw the calculated volume of BAC water from the BAC water vial. For most peptides, 1–2mL is standard. Use the calculator above to determine the exact volume.

Inject down the vial wall at 45°

Tilt the peptide vial at 45 degrees. Slowly depress the plunger so the water runs down the inside wall of the vial, not directly onto the powder cake. This prevents denaturation from mechanical force.

Swirl — do not shake

Gently roll the vial between your palms in a slow circular motion until the powder fully dissolves. The solution should become clear and colourless. Never shake — agitation denatures peptide bonds.

Label and refrigerate

Write the peptide name, date reconstituted, concentration (mcg/mL), and vial size on the label using a permanent marker. Store immediately at 2–8°C, away from the refrigerator door. Discard after 28–30 days.

How to Read an Insulin Syringe for Peptide Dosing

Syringe units are a volume measurement only — they are not International Units (IU) of any drug. On a U-100 syringe, one unit = 0.01mL. The marking system exists purely to measure volume; the term “unit” here has no relationship to hormonal or biological units of activity.

Syringe comparison: 0.3mL vs 0.5mL vs 1.0mL

U-100 0.3mL

30 total units • 1 unit increments • Best for doses under 20 units • Most precise

U-100 0.5mL

50 total units • 1 unit increments • Good for doses 10–40 units • Most common

U-100 1.0mL

100 total units • 2 unit increments • For larger volumes • Use for GLP-1 doses

Bacteriostatic Water vs Sterile Water for Peptides: Which Should You Use?

	Bacteriostatic Water	Sterile Water	Normal Saline (0.9%)	BAC Saline
Preservative	0.9% benzyl alcohol	None	None	0.9% benzyl alcohol
Shelf life (opened)	28 days refrigerated	Single use only	Single use only	28 days refrigerated
Multi-dose safe	Yes	No	No	Yes
Best for	Most research peptides	One-off single doses	Nasal sprays	NAD+, nasal multi-dose

NAD+ requires BAC saline

NAD+ (nicotinamide adenine dinucleotide) is best reconstituted with bacteriostatic saline (0.9% NaCl with 0.9% benzyl alcohol) rather than standard BAC water. This improves stability and is isotonic, which reduces injection discomfort.

Nasal peptides need sterile saline

Peptides administered intranasally — including Semax, Selank, VIP, and Oxytocin — should be reconstituted in sterile saline (0.9% NaCl, no preservative) or sterile water. Benzyl alcohol is a mucosal irritant at nasal concentrations and should be avoided for intranasal use.

How Long Do Reconstituted Peptides Last? Storage Guide

Storage condition	Duration	Notes
Lyophilised, −20°C freezer	Up to 2 years	Optimal long-term storage
Lyophilised, room temp (<25°C, dry)	2–3 months	Keep sealed and away from light
Reconstituted, 2–8°C refrigerator	28–30 days	Most common research use case
Reconstituted, room temperature	<24 hours	Not recommended for repeated use
Reconstituted, frozen at −20°C	Not recommended	Freeze-thaw cycles degrade peptides

Always label the vial with the reconstitution date and discard after 28 days regardless of how much remains.
Store reconstituted vials upright in the main body of the refrigerator, not in the door (temperature fluctuates there).
Protect from light — a small piece of aluminium foil around the vial prevents photodegradation.
Never freeze a reconstituted solution; ice crystal formation during freezing mechanically damages peptide structure.
Keep lyophilised vials away from humidity — use desiccant packs in storage containers.
If the solution appears cloudy, discoloured, or has visible particulates after reconstitution, discard it.

10 Common Peptide Reconstitution Mistakes to Avoid

Confusing mg and mcg. One milligram equals 1,000 micrograms. A 5mg vial contains 5,000mcg. Always convert to the same unit before calculating. The calculator handles this automatically.
Confusing syringe units with International Units. On an insulin syringe, “units” measure volume only. 10 units on a U-100 syringe = 0.1mL. This has nothing to do with IU of hormones or other biologics.
Shaking the vial. Vigorous shaking creates foam and mechanical stress that denatures peptide bonds. Always swirl gently in a circular motion until the powder dissolves completely.
Spraying water directly onto the powder. Direct water pressure disrupts the lyophilised cake. Instead, tilt the vial and let BAC water run slowly down the inner wall to dissolve the powder from the sides.
Using sterile water for multi-dose vials. Sterile water contains no preservative. Using it for repeated-access vials creates bacterial contamination risk. Use bacteriostatic water for any vial you will access more than once.
Adding the wrong BAC water volume. Changing the BAC water volume changes the concentration and therefore the units per dose. Always re-calculate units if you use a different water volume than planned.
Failing to label the vial. An unlabelled vial is a safety hazard. Label with: peptide name, date mixed, concentration (mcg/mL), and your initials. Discard any unlabelled reconstituted vials.
Storing in the refrigerator door. Door temperatures fluctuate every time the fridge opens. Store peptide vials in the main body of the refrigerator where temperature remains stable at 2–8°C.
Using a vial beyond 30 days. Even if solution remains in the vial, most reconstituted peptides degrade meaningfully after 28–30 days. Discard on or before the 28-day mark from the reconstitution date.
Not swabbing the septum before drawing. Always swab the rubber septum with a fresh alcohol swab before each draw, even if the vial was recently opened. Allow to air-dry before piercing.
