Peptide Blend Calculator — Calculate Reconstitution for Multi-Peptide Vials
Work out the arithmetic of a fixed-ratio blend: enter each ingredient’s mass, the final solution volume and a specified amount of the first ingredient. See the corresponding volume and the amounts of every other ingredient. The tool does not choose a treatment, diluent or preparation method.
Interactive Peptide Blend Calculator
Enter each ingredient’s amount in the whole vial, not the vial’s total blended mass for every ingredient. Use final solution volume, not container capacity. Presets are editable examples; check all entries against the actual product.

Peptides
Enter the actual ingredients and amounts you have verified. Amounts are used only to calculate the fixed ratio.
Container capacity is a constraint for this arithmetic; it does not determine the final solution volume.
Enter the final solution volume for arithmetic only. This field is not a water or diluent recommendation and does not establish compatibility.
This is an entered amount for the arithmetic example, not a dose recommendation.
U-100 Volume Scale
U-100 units are volume-scale units, not drug units; 100 units/mL defines the scale. Tick spacing and syringe capacity vary; the selected scale does not establish syringe capacity or measurement suitability.

Calculated Concentration Per Peptide
Each calculated portion preserves the fixed ratio of the entered masses. This arithmetic does not establish a treatment combination, compatibility, sterility, or stability.
BPC-157

25.00 mcg/unit
100.00 mcg per calculated portion

Fixed Ratio from Entered Masses
BPC-157: 50.0% | TB-500: 50.0%
The ratio is an arithmetic relationship only; it is not a protocol or a claim that the ingredients should be combined.
Calculation Summary (not instructions):
- Calculated volume-scale quantity: 4.00 U-100 units of the entered solution
- Calculated primary mass: 100.00 mcg

How Peptide Blends Work
A blend contains multiple ingredients in one formulation. For a uniformly dissolved mixture, each withdrawal contains those ingredients in the same mass ratio. A 5 mg amount of ingredient A with 10 mg of ingredient B gives a 1:2 ratio, regardless of how much diluent is added.
Arithmetic example, not a treatment suggestion: with those 5 mg and 10 mg amounts in 2 mL of final solution, A is 2,500 mcg/mL and B is 5,000 mcg/mL. A volume containing 100 mcg of A is 0.04 mL, which also contains 200 mcg of B. On the U-100 volume scale, 0.04 mL corresponds to the position labeled 4 units, not necessarily four tick marks.
Formula: concentration in mcg/mL = ingredient mass in mg × 1,000 ÷ final volume in mL. Calculated volume = specified amount in mcg ÷ that ingredient’s concentration. U-100 markings = mL × 100. These markings describe volume, not a peptide’s biological units. The example gives 50 theoretical complete portions before any loss; it says nothing about how long a preparation remains usable.
Popular Peptide Blends
These names appear in this tool and the linked guides. Names alone do not specify a standardized formulation, ingredient identity or evidence of benefit. Read ingredient-specific evidence separately from claims about a combined product.
Wolverine Stack (BPC-157 & TB-500)
The tool’s illustrative preset contains 5 mg each of BPC-157 and TB-500. This is a calculation example, not proof of combined healing benefits or an established safety record. Explore the evidence and reported uses in our Wolverine Stack peptide guide.
IPA/CJC Stack (CJC-1295 & Ipamorelin)
The illustrative preset contains 5 mg each of ipamorelin and CJC-1295. It does not establish an athlete protocol, compatibility or clinical synergy. Exact CJC formulation matters; do not infer its identity from a stack nickname. See our CJC-1295 & Ipamorelin dosage guide.
GLOW Blend: Check the Ingredient List
This calculator’s existing example uses GHK-Cu 50 mg and BPC-157 5 mg. That is not a universal GLOW formula, and it is not a KPV/LL-37 mixture. Replace the example with the actual labeled ingredients and amounts; use Custom Blend if they differ. Explore our GLOW Blend peptide guide.
Weight Loss Stack
The AOD-9604/CJC-1295 example does not establish weight-loss efficacy or a recommended combination. A marketing name should not determine the entries or the treatment decision. Context is available in our peptide stack weight loss guide.
How to Reconstitute a Peptide Blend
Pre-Blended Vials
Start with the product’s own preparation directions. The bacteriostatic-water label directs users to the drug manufacturer for vehicle and dilution instructions; it does not authorize one method for every peptide. Check these details before using the calculator:
- Identify every ingredient and its individual mass.
- Confirm the supplied diluent and preparation instructions.
- Distinguish the amount of liquid added from the final solution volume.
- Enter the specified primary amount and check every accompanying component amount.
- Keep the supplied storage and discard instructions with the product.
Mixing Separate Peptides
Combining separate medicines is a preparation decision, not a calculator function. CDC identifies combining medications as sterile-compounding work. A pharmacist needs formulation-specific information; the following is an information checklist, not a home-mixing recipe:
- Exact ingredients, forms, concentrations and excipients.
- Evidence of compatibility for the intended formulation.
- Preparation environment and handling requirements.
- Verified final concentrations and appropriate measurement device.
- Product-specific labeling, storage and discard period.
Water Volume Considerations
In the example above, changing final volume from 2 mL to 4 mL halves both concentrations. The volume containing 100 mcg of A becomes 0.08 mL, still containing 200 mcg of B. The ratio and theoretical 50-portion count stay unchanged. The calculator cannot select an “ideal” concentration or guarantee a displayed volume can be measured accurately with your syringe.
Safety Considerations
Peptide Compatibility
Dissolving in the same liquid is not a compatibility test. The diluent label notes that incompatibility can involve the vehicle, combined drugs or benzyl alcohol. An ingredient dropdown or a correct ratio does not resolve that question. Obtain instructions for the exact formulation rather than relying on the stack name.
Storage & Contamination Prevention
CDC injection-safety guidance distinguishes contamination control from stability. Preservatives do not fully protect against contamination. Its general 28-day opened-multidose-vial rule has manufacturer-specific exceptions and is not a shelf-life validation for arbitrary blends. In practice:
- Follow the preparation’s specified temperature, light protection and discard instructions.
- Use fresh sterile needles and syringes with aseptic handling.
- Do not pool leftover single-dose vial contents for later use.
- Do not assume refrigeration or freezing extends a supplied discard date.
- Ask the pharmacy when instructions are missing or storage conditions were exceeded.
For detailed storage guidance, see our peptide storage guide.
Frequently Asked Questions
No. Sharing a solvent does not establish compatibility. This calculator performs arithmetic; it cannot validate a mixture or a preparation procedure. Confirm the exact formulation with the dispensing pharmacist.
Use the diluent specified for the exact product. Bacteriostatic water is not universally suitable, and the calculator does not select a solvent. Do not substitute household water or improvise sterilization.
There is no universal shelf life for arbitrary peptide blends. Follow the formulation-specific storage and discard instructions. An opened diluent vial’s use period is not a validated stability period for a newly prepared mixture.
Each component shares the same final solution volume. Its concentration equals its own mass divided by that volume. Adding diluent changes all concentrations together; it cannot independently change one component’s proportion in an existing blend.
For unchanged ingredient masses, a larger final volume lowers every concentration and increases the volume containing a specified amount. That arithmetic does not establish whether a preparation can be used. If preparation differs from the supplied instructions, ask the pharmacist before using it.
Adding more liquid changes the concentration; it does not restore lost potency or reset a discard date. Do not assume freezing, thawing or dividing a mixture into smaller containers extends its usable life. Follow the exact preparation’s instructions.
