View Certificates

US Sourced

Every compound is synthesized in U.S. cGMP-aligned facilities — sourced, handled, and quality-gated on American soil.

US Lab Tested

Independent American laboratories verify identity and purity on every lot by HPLC and mass spectrometry before release.

Answers

Questions, answered

How do you verify identity and purity?

Every lot is tested by independent third-party laboratories using HPLC for purity and mass spectrometry for identity confirmation. We publish each certificate of analysis openly in our COA Library, keyed to lot number for full traceability.

When are orders dispatched?

Orders placed before 12pm PT ship the same business day from our California facility. Standard domestic delivery is 2–4 business days with tracked carrier service. Cold-chain handling on temperature-sensitive products at no extra charge.

How should I store these compounds?

Lyophilized peptides arrive at ambient temperature and should be moved to -20°C upon arrival. Once reconstituted, store at 4°C and use within 4 weeks for best stability. See product detail pages for compound-specific guidance.

Do you offer bulk or institutional pricing?

Yes. Volume discounts begin at 10 units of any single compound, and we offer custom quoting for academic departments, contract research organizations, and biotech accounts. Contact our research support team to set up an institutional account.

Frequently asked

Common questions from research customers. If you can't find what you need, our team responds within one business day.

What does "research use only" actually mean?

Every product on this site is sold strictly for in vitro laboratory research. They are not for human or veterinary consumption and are not intended to diagnose, treat, cure, or prevent any condition. Purchase confirms you are a qualified researcher or authorized purchaser.

How do you verify identity and purity?

Every lot is tested by independent third-party laboratories using HPLC for purity and mass spectrometry for identity confirmation. We publish each certificate of analysis openly in our COA Library, keyed to lot number for full traceability.

When are orders dispatched?

Orders placed before 12pm PT ship the same business day from our California facility. Standard domestic delivery is 2–4 business days with tracked carrier service. Cold-chain handling on temperature-sensitive products at no extra charge.

Do you ship internationally?

We currently ship within the continental United States. International shipping requires importer documentation that varies by jurisdiction — contact our team if you need a customs-cleared route to your laboratory.

What payment methods do you accept?

All major credit cards (Visa, Mastercard, American Express, Discover), bank transfer for institutional accounts, and select digital wallets. Net-30 invoicing available for verified academic and biotech accounts.

How should I store these compounds?

Lyophilized peptides arrive at ambient temperature and should be moved to -20°C upon arrival. Once reconstituted, store at 4°C and use within 4 weeks for best stability. See product detail pages for compound-specific guidance.

What's your return policy?

Because of the nature of laboratory reagents, opened product cannot be returned. If a shipment arrives damaged or with a quality defect, contact us within 7 days with the lot number and photos and we'll replace or refund the affected items.

Do you offer bulk or institutional pricing?

Yes. Volume discounts begin at 10 units of any single compound, and we offer custom quoting for academic departments, contract research organizations, and biotech accounts. Contact our research support team to set up an institutional account.

About

For research use only. Not for human consumption.

From The Literature

Read the abstract

Selected research

    Independently Verified, End To End

    Every lot we release is documented. Every documented number is independent. No marketing chemistry, no rounded figures — just the actual instrument output.

    Third-Party HPLC

    Every batch is analyzed by an independent ISO-17025 laboratory before release. We publish the raw chromatogram with each lot.

    Mass Spectrometry

    Sequence confirmation by ESI-MS. We don't ship product whose molecular weight doesn't match the theoretical mass to within 1 dalton.

    Cold-Chain Logistics

    Insulated shipping with temperature indicators. If the chain breaks, we replace the order.

    Why Pure Point Labs

    Built On A Single Principle: Prove It.

    The research community deserves better than marketing claims. Pure Point Labs publishes every certificate of analysis, every chromatogram, every lot number — so the researcher, not the supplier, decides what's good enough. If we can't show you the data, we don't ship the vial.
