How do I reconstitute peptides with bacteriostatic water?

Draw bacteriostatic water into a syringe, inject slowly down the vial wall (not directly onto powder), then gently swirl until dissolved. Never shake. Store refrigerated at 2-8C and use within 28 days.

How many units should I draw on an insulin syringe?

1 mL equals 100 units on a standard insulin syringe. Divide your required volume in mL by 0.01 to get units. For example, 0.25 mL = 25 units. Use the smallest syringe that fits your dose for better precision.

What syringe size should I use for peptide injections?

0.3 mL (30 unit) syringes offer the best precision for small doses under 0.3 mL. 0.5 mL (50 unit) syringes work for most peptides. 1 mL (100 unit) syringes are needed for larger dose volumes.

How to use: Enter your vial size and the amount of bacteriostatic water you'll add. Then enter your desired dose to see exactly how much to draw.

Tip: 1 mL = 100 units on an insulin syringe. Draw slowly to ensure accuracy.

DHB Dosing Protocols

Goal	Dose	Frequency
Lean Bulk - Moderate	200-300 mg/week	2-3x per week (cypionate)
Lean Bulk - Standard	300-400 mg/week	2-3x per week (cypionate)
Cutting / Recomposition	200-300 mg/week	2-3x per week (cypionate)

Reconstitution Steps

01 Wash hands thoroughly and prepare a clean work surface
02 Warm the vial gently (body temperature) to reduce oil viscosity and help keep compound in solution -- this may slightly reduce PIP
03 Wipe vial stopper with alcohol swab and allow to dry
04 Draw air into syringe equal to the volume of DHB to be withdrawn
05 Insert drawing needle through vial stopper and inject air to equalize pressure
06 Invert vial and withdraw the prescribed dose, tapping to remove air bubbles
07 Inspect for any visible crystals or cloudiness in the drawn oil -- if crashed, warm gently until fully dissolved before injecting
08 Switch to injection needle (do not inject with drawing needle)
09 Clean injection site with alcohol swab in circular motion outward
10 Insert needle at 90-degree angle into ventrogluteal, vastus lateralis, or deltoid muscle
11 Inject slowly over 30-60 seconds (slower injection may reduce PIP severity)
12 Withdraw needle, apply gentle pressure with gauze, dispose of needle in sharps container
13 Massage the injection site gently after injection to help disperse the oil
