Sermorelin Reconstitution with Bacteriostatic Water
Standard research-protocol ratio: 2 mL bacteriostatic water per 3 mg sermorelin vial → 1.5 mg/mL. At that concentration, a 300 mcg research dose draws to 0.2 mL. Research and laboratory use only.
Direct Answer
3 mg sermorelin + 2 mL bacteriostatic water = 1.5 mg/mL. Use 0.9% benzyl alcohol bacteriostatic water for the 28-day refrigerated multi-draw window. Some research protocols prefer higher concentrations (3 mg + 1 mL = 3 mg/mL) to minimize injection volume.

|---|---|---|---|
| 2 mg | 1.0 mL | 2.0 mg/mL | 0.15 mL for 300 mcg |
| 3 mg | 2.0 mL | 1.5 mg/mL | 0.20 mL for 300 mcg |
| 3 mg | 1.0 mL | 3.0 mg/mL | 0.10 mL for 300 mcg |
| 5 mg | 2.0 mL | 2.5 mg/mL | 0.12 mL for 300 mcg |
| 10 mg | 2.0 mL | 5.0 mg/mL | 0.06 mL for 300 mcg |
Frequently Asked Questions
How much bacteriostatic water do I add to a 3 mg sermorelin vial?
Standard research-protocol ratio: 2 mL bacteriostatic water per 3 mg lyophilized sermorelin vial → 1.5 mg/mL final concentration. At that concentration, a 300 mcg research dose draws to 0.20 mL. Some research protocols prefer 1 mL water for 3.0 mg/mL to reduce injection volume on small-dose work.
How much for a 5 mg or 10 mg sermorelin vial?
5 mg + 2 mL bacteriostatic water = 2.5 mg/mL (300 mcg dose → 0.12 mL). 10 mg + 2 mL = 5 mg/mL (300 mcg dose → 0.06 mL). Higher-concentration ratios are appropriate when minimizing draw volume is a research-protocol priority.
Why use bacteriostatic water for sermorelin reconstitution?
Sermorelin research protocols are multi-dose (typically daily evening doses over 8–12 week research cycles). The 0.9% benzyl alcohol preservative maintains the reconstituted vial's safe in-use window across 28 days refrigerated. Sterile water has no preservative and can't support multi-draw protocols.
How long is reconstituted sermorelin stable in bacteriostatic water?
Sermorelin in bacteriostatic water is rated for 28 days refrigerated at 2–8 °C — matching the bacteriostatic in-use window. Some research literature reports shorter empirical stability (10–14 days) due to sermorelin's chemistry; verify against published methods. Discard immediately on cloudiness, color change, or particulates regardless of date.
What size insulin syringe is standard for sermorelin draws?
Insulin syringes (1.0 mL) are standard. For sub-0.10 mL draws on higher-concentration ratios, a 0.5 mL low-dose insulin syringe (half-unit gradations) provides better precision than a 1 mL syringe.
