Does every bacteriostatic water order include a Certificate of Analysis (COA)?

Yes. Every order ships with a full COA confirming HPLC purity, sterility, and benzyl alcohol concentration — giving labs and compounding pharmacies complete traceability.

What is bacteriostatic water used for?

Bacteriostatic water is used for reconstituting peptides, medications, and injectable compounds. It contains 0.9% benzyl alcohol which inhibits bacterial growth, making it safe for multi-dose vials in research and compounding.

Is Renew Lab Group bacteriostatic water USP grade?

Yes. All Renew Lab Group bacteriostatic water is produced to USP standards with full sterility, endotoxin, and pH testing. A certificate of analysis (COA) is included with every order.

Do you ship bacteriostatic water nationwide?

Yes. Renew Lab Group ships USP-grade bacteriostatic water to all 50 states from our Houston, TX facility. Most orders ship same or next business day.

What HPLC lab testing services do you offer?

Renew Lab Group offers HPLC analysis, LC-MS testing, purity testing, compound identification, pharmaceutical analysis, and custom research testing from our Houston, TX laboratory.

What is the difference between bacteriostatic water and sterile water?

Bacteriostatic water contains 0.9% benzyl alcohol preventing bacterial growth for multi-dose use. Sterile water has no preservative and is single-dose only. For peptide reconstitution, bacteriostatic water is preferred.

How much does peptide testing cost at Renew Lab Group?

Standard Identity + Purity testing (HPLC-UV + LC-MS/MS) is $189 per sample. GLP-1 class peptides (semaglutide, tirzepatide, retatrutide) are $289 per sample. Blind/unlabeled ID is $225. Volume pricing: 5-9 samples $165 each, 10+ samples $145 each. Rush turnaround adds $75 per sample.

Do I need a prescription to submit a peptide sample for testing?

No. Renew Lab Group accepts samples from individuals, practitioners, and pharmacies without requiring a prescription or DEA license for analytical identity and purity testing.

What is the difference between HPLC and LC-MS/MS testing?

HPLC measures purity (the percentage of your compound vs. impurities). LC-MS/MS confirms identity (verifying the molecular mass and fragment ions match the target peptide). Both tests together give you the complete picture on one Certificate of Analysis.

How long does peptide testing take?

Standard Identity + Purity testing is 3-5 business days. 48-hour rush is available for +$75 per sample. Sterility testing requires a minimum of 15 business days due to the USP 71 14-day incubation requirement.

Does Renew Lab Group manufacture bacteriostatic water?

Yes. In addition to lab testing services, Renew Lab Group manufactures HPLC-tested bacteriostatic water (BAC water) with COA in an ISO cleanroom in Houston, TX. Available in 10mL, 20mL, and 50mL vials for research, peptide reconstitution, and compounding pharmacies — shipped nationwide.

Why does HPLC testing matter for research peptide quality?

High-Performance Liquid Chromatography (HPLC) separates a target peptide from impurities to quantify purity precisely. Paired with mass spectrometry for identity confirmation and documented in a Certificate of Analysis with chromatogram data, it verifies the greater than 98 to 99 percent purity that supports reliable research outcomes.

Why HPLC Matters for Research Peptide Quality

A label can say 99% pure. HPLC is what proves it.

Trust the data behind every batch:

HPLC delivers precise purity percentages by separating the target compound from impurities
Combined with mass spectrometry for complete identity verification
Reputable suppliers provide full Certificates of Analysis with chromatogram data
High purity, generally above 98-99%, supports more reliable research outcomes
Renew Labs compounds are lab-verified for consistency researchers can count on

Without a chromatogram, there is no proof. Always ask for the Certificate of Analysis.

For Research Use Only. Not for Human Consumption.
