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.

Gonadorelin Dosing Protocols

Goal	Dose	Frequency
Diagnostic testing	100 mcg	Single injection
Fertility support	50-100 mcg	2-3x weekly
Pulsatile therapy	5-20 mcg per pulse	Every 90-120 min
TRT adjunct	100-200 mcg	2-3x weekly

Reconstitution Steps

01 Clean work area and hands thoroughly
02 Calculate required BAC water volume
03 Draw BAC water into syringe
04 Inject slowly down vial side (not directly onto powder)
05 Gently swirl until dissolved (never shake)
06 Store in refrigerator, use within 14 days

Quick Reference

Typical Dose 100-200 mcg for single injections; 5-20 mcg per pulse for pulsatile therapy

Frequency 2-3 times weekly for fertility/TRT support; every 90-120 minutes for pulsatile therapy; single dose for diagnostic

Half-life 2-4 minutes

Storage Lyophilized: 2-8°C refrigerated; Reconstituted: 2-8°C refrigerated, use within 14 days due to short stability

Cycle Varies - diagnostic single use, fertility therapy ongoing, TRT support continuous
