Frequently Asked Questions

What sets SFVlab.com peptides apart from compounding pharmacies? Toggle

Our peptides are tested to a purity standard of >99%, confirmed by third-party Certificates of Analysis (COAs). Most compounding pharmacies and peptide labs only release peptides at 96–98% purity, often without disclosing full analytical data. We hold ourselves to a higher standard of potency, transparency, and precision—every time.

Do your peptides meet any sterility or safety standards? Toggle


Yes. Every batch is rigorously tested and compliant with:

» USP <71> Sterility Testing
» USP <85>/<81> Endotoxin (Pyrogen) Limits

Our lab-grade quality ensures products are safe for clinical and research use, with documented pharmaceutical compliance.

How long is the shelf life? Toggle

When refrigerated properly, our lyophilized (freeze-dried) peptides remain stable for up to 2 years. That’s far longer than compounded peptides, which often expire within 30–90 days. Our extended shelf life helps you manage inventory efficiently and reduce waste.

What is Net Peptide Content and how do you calculate it? Toggle

Net peptide content reflects the true amount of active peptide in the vial, excluding excipients and moisture. We round up the net peptide content to ensure you receive at least the amount listed on the label—no games, no shorting.

How fast do you ship? Toggle

We process and ship most orders within 24–48 hours, and typically within 24 hours. No delays, no waiting on pharmacy backlogs. That means you can start protocols sooner and serve your clients with confidence.

How do you ensure quality control? Toggle

Every product undergoes:
» Full third-party lab testing
» Batch-level COAs
» Sterility and endotoxin validation
» Purity screening to ≥99% standard
