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.

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

KPV Reference

KPV Dosing Protocols

Goal	Dose	Frequency
General anti-inflammatory	200-300mcg	Once daily
Active inflammation	250mcg	Twice daily
Autoimmune support	500mcg	Once daily
Acute flare-ups	500mcg	2x daily for 1 week, then reduce

Reconstitution Steps

01 Clean vial with alcohol pad
02 Add 1mL bacteriostatic water to 1mg vial (1000mcg/mL)
03 Or add 2mL for 500mcg/mL concentration
04 Gently swirl - dissolves easily
05 Solution should be clear and colorless
06 Label with concentration and date
07 Refrigerate immediately

Quick Reference

Typical Dose 200-500 mcg per injection

Frequency 1-2 times daily (once for maintenance, twice for active inflammation)

Half-life 1-2 hours

Storage Lyophilized: Room temperature. Reconstituted: 2-8°C, refrigerate immediately

Cycle 4-8 weeks
