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.

How are premium research peptides verified for purity?

Premium research peptides are verified using HPLC to separate the target from impurities and quantify purity, often paired with mass spectrometry for identity confirmation. Verification is documented in a Certificate of Analysis with a clear chromatogram from third-party testing.

HPLC Purity Testing: How Premium Research Peptides Are Verified

This peak is the difference between verified and “trust me.”

How premium research compounds are verified:

High-Performance Liquid Chromatography separates the target compound from impurities
Quantifies purity percentage with precision
Often paired with mass spectrometry for full identity confirmation
Look for detailed Certificates of Analysis showing clear chromatograms
Renew Labs compounds undergo rigorous third-party HPLC verification

A clean chromatogram is a receipt for quality. Always ask for it.
