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 20 units on a U-100 insulin syringe. 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.

| Vial Strength | BAC Water to Add | Final Concentration | Draw Volume (Example) |
|---|---|---|---|
| 2 mg | 1.0 mL | 2.0 mg/mL | 0.15 mL (15 units) for 300 mcg |
| 3 mg | 2.0 mL | 1.5 mg/mL | 0.20 mL (20 units) for 300 mcg |
| 3 mg | 1.0 mL | 3.0 mg/mL | 0.10 mL (10 units) for 300 mcg |
| 5 mg | 2.0 mL | 2.5 mg/mL | 0.12 mL (12 units) for 300 mcg |
| 10 mg | 2.0 mL | 5.0 mg/mL | 0.06 mL (6 units) 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 (20 units on a U-100 insulin syringe). 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 → 12 units on a U-100 insulin syringe). 10 mg + 2 mL = 5 mg/mL (300 mcg dose → 6 units). Higher-concentration ratios are appropriate when minimizing injection volume per draw 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?
U-100 insulin syringes (1.0 mL, 100-unit scale) are standard. For sub-0.10 mL draws on higher-concentration ratios, a 0.5 mL low-dose insulin syringe with half-unit gradations provides better precision than a 1 mL syringe.
Where do I source verified bacteriostatic water for sermorelin research?
BAC Water Depot (bacwaterdepot.com) ships USA-manufactured 10 mL bacteriostatic water with 0.9% benzyl alcohol, ISO 9001:2015 facility, three independent third-party laboratories per lot, per-lot CoA published. Single $9.99, 10-pack $74.99, bulk from $6.49/vial.
