Dosage Calculator
A harm reduction tool to help understand peptide reconstitution and dosing. This calculator is for educational purposes only.
This calculator is for educational purposes only and does not constitute medical advice. Most peptides are NOT FDA-approved for human use and may carry significant health risks.
- There are no established safe dosages for most peptides
- Gray market peptides may be contaminated, mislabeled, or contain no active ingredient
- Self-injection carries serious risks including infection and nerve damage
- Always consult with a qualified healthcare professional before using any peptide
Common sizes: 2mg, 5mg, 10mg

Summary
Add 2ml of bacteriostatic water to your 5mg vial. For a 250mcg dose, draw 10.0 units on a standard insulin syringe (100 units = 1ml). This vial will provide approximately 20 doses.
Reconstitution Tips
- Always use bacteriostatic water, not sterile water
- Inject water slowly along the vial wall, never directly onto powder
- Gently swirl to mix - never shake
- Store reconstituted peptides in refrigerator
- Most reconstituted peptides are good for 4-6 weeks refrigerated
Injection Safety
- Always use new, sterile needles
- Clean injection site with alcohol swab
- Rotate injection sites to prevent tissue damage
- Subcutaneous injections go into fat tissue (belly, thigh)
- Seek medical attention for signs of infection
When to Seek Medical Help
- Severe allergic reaction (difficulty breathing, swelling)
- Signs of infection (redness, warmth, pus, fever)
- Unusual or severe side effects
- Chest pain or heart palpitations
Insulin Syringe Reference
Understanding syringe markings for accurate dosing
Key Points:
- Read at the TOP of the black rubber stopper
- Each small line = 1 unit (0.01ml)
- Numbered lines are every 10 units
- Hold syringe at eye level for accuracy
- Flick out air bubbles before measuring
Dilution Reference Guide
Concentration per 10 units (0.1ml) based on water volume
| BAC Water | 5mg Vial | 10mg Vial | Notes |
|---|---|---|---|
| 1ml | 500mcg per 10 units | 1000mcg per 10 units | High concentration - harder to measure small doses |
| 1.5ml | 333mcg per 10 units | 667mcg per 10 units | Moderate concentration |
| 2ml | 250mcg per 10 units | 500mcg per 10 units | Standard - good balance |
| 2.5ml | 200mcg per 10 units | 400mcg per 10 units | Lower concentration |
| 3ml | 167mcg per 10 units | 333mcg per 10 units | Easy to measure small doses |
Formula: (Vial mg × 1000) ÷ (Water ml × 10) = mcg per 10 units. For example: 5mg vial with 2ml water = (5 × 1000) ÷ (2 × 10) = 250mcg per 10 units.
Supply Checklist
What you need for peptide reconstitution and administration

Required29-31 gauge, 1/2 inch needle typical for subQ
Alcohol Swabs
Required70% isopropyl alcohol for cleaning injection site and vial tops
Sharps Container
RequiredSafe disposal of used needles - never reuse or discard in trash
Mixing Syringes (larger gauge)
Optional18-21 gauge makes drawing BAC easier, optional
Refrigerator Storage
RequiredReconstituted peptides must be refrigerated (2-8°C / 36-46°F)
Timer/Alarm App
OptionalHelpful for consistent dosing times
