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.

HCG Dosing Protocols

Goal	Dose	Frequency
TRT Adjunct (Low)	250-500 IU	Every other day
TRT Adjunct (Standard)	500-1000 IU	Twice weekly
HCG Monotherapy	1500-2000 IU	2-3x weekly
Fertility (with FSH)	1500-2000 IU	2-3x weekly
Cryptorchidism (Pediatric)	1000-5000 IU	2-3x weekly for 3-4 weeks
Ovulation Trigger (Female)	5000-10,000 IU	Single dose
PCT Protocol	1000-1500 IU	Every other day for 2-3 weeks

Reconstitution Steps

01 Remove vial and diluent from packaging
02 Clean rubber stoppers with alcohol swabs
03 Draw diluent into syringe (typically 1-2mL provided)
04 Slowly inject diluent into HCG vial, aiming at vial wall
05 Gently swirl to dissolve - do not shake vigorously
06 Allow to sit until completely dissolved and clear
07 Calculate concentration (e.g., 5000 IU in 2mL = 2500 IU/mL)
08 Label with reconstitution date and concentration
09 Store reconstituted HCG at 2-8°C
10 Use within 30-60 days

Quick Reference

Typical Dose 250-1500 IU (lower for TRT adjunct, higher for fertility)

Frequency 2-3 times weekly, or every other day for lower doses

Half-life 24-36 hours

Storage Lyophilized: Room temperature. Reconstituted: 2-8°C, use within 30-60 days

Cycle Ongoing with TRT or 3-6 months for fertility protocols
