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.

Nandrolone Reference

Nandrolone Dosing Protocols

Goal	Dose	Frequency
TRT Adjunct - Joint Support	50-100 mg/week	1x per week (decanoate)
Therapeutic - Anemia / Wasting	100-200 mg/week	1x per week (decanoate)
Performance Enhancement - Moderate	200-400 mg/week	1x per week (decanoate) or split into 2 injections
NPP Protocol - Shorter Cycle	200-350 mg/week	Every other day or 3x per week

Reconstitution Steps

01 Wash hands thoroughly and prepare a clean work surface
02 Wipe vial stopper with alcohol swab and allow to dry
03 Draw air into syringe equal to the volume of nandrolone to be withdrawn
04 Insert drawing needle through vial stopper and inject air to equalize pressure
05 Invert vial and withdraw the prescribed dose, tapping to remove air bubbles
06 Switch to injection needle (do not inject with drawing needle)
07 Clean injection site with alcohol swab in circular motion outward
08 Insert needle at 90-degree angle into ventrogluteal, vastus lateralis, or deltoid muscle
09 Aspirate briefly (optional per current guidelines), then inject slowly over 10-30 seconds
10 Withdraw needle, apply gentle pressure with gauze, dispose of needle in sharps container
