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.

Thymosin Beta-4 Reference

Thymosin Beta-4 Dosing Protocols

Goal	Dose	Frequency
Acute Wound Healing	1.6mg	Daily
Cardiac Protection	42mg	Single dose
Chronic Tissue Repair	6mg	Twice weekly
Neurological Recovery	30mg	Three times over 72 hours
General Regeneration	2-5mg	Daily or every other day

Reconstitution Steps

01 Allow lyophilized powder to reach room temperature before reconstitution
02 Add bacteriostatic water slowly to vial wall, avoiding direct powder contact
03 Gently swirl (do not shake vigorously) until completely dissolved
04 Inspect solution for clarity—should be clear and colorless
05 Store reconstituted solution at 2-8°C and use within 14 days
06 Use proper aseptic technique and rotate injection sites

Quick Reference

Typical Dose 2-6mg per injection (varies by protocol and severity)

Frequency Daily for acute healing, 2x weekly for maintenance/chronic conditions

Half-life Dose-dependent; relatively short (exact values not established)

Storage Reconstituted: 2-8°C, use within 14 days

Cycle 2-12 weeks depending on healing needs
