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.

Cerebrolysin Dosing Protocols

Goal	Dose	Frequency
Small Volume IV	Up to 10mL	Once daily
Intramuscular	Up to 5mL	Once daily
Acute Stroke	20-50mL	Once daily for 10-21 days
Traumatic Brain Injury	20-50mL	Once daily for 7-30 days

Reconstitution Steps

01 Break ampoule and extract Cerebrolysin immediately before use
02 For direct injection: Up to 10 mL IV undiluted (slow 3 minutes) or 5 mL IM
03 For infusion: Dilute 10-50 mL to minimum 100 mL with compatible solution
04 Start infusion immediately after dilution—infuse within 15 minutes
05 Flush IV catheter with sodium chloride before and after administration
06 Use disposable one-way infusion sets; discard after use
