Frequently Asked Questions

Comprehensive answers covering analytical testing methods, storage protocols, compliance, and ordering.

Quality & Testing Protocol

We utilize Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) coupled with UV spectrophotometry at 214 nm to measure chromatographic purity. Molecular identity is independently confirmed via Electrospray Ionization Mass Spectrometry (ESI-MS). Each production run is also screened for heavy metal traces and residual trifluoroacetic acid (TFA).

All released reference batches are certified at ≥ 99.00% purity. Most lots average between 99.50% and 99.85%. Any batch that fails to clear the 99.00% purity benchmark is immediately quarantined and rejected.

Yes. Every batch carries an individual certificate of analysis showing the exact lot number, test date, HPLC peak area percentage, and mass spectrum. The identical lot number is laser-printed on the vial label for full traceability.

Ordering & Compliance

Orders are strictly accepted from universities, biotechnology organizations, pharmaceutical companies, diagnostic testing facilities, and qualified researchers aged 21 or older. All purchasers must agree to our research use terms prior to completing checkout.

No. All products sold by Club Pep are synthesized strictly for in-vitro laboratory research, biological assays, and analytical calibration standards. They are NOT for human, veterinary, medical, diagnostic, or therapeutic use under any circumstances.

Shipping & Storage Guidelines

Lyophilised vials are packed in insulated containers with cold refrigerant packs to preserve structural integrity during transit. Orders placed before 2:00 PM EST ship same day via priority courier service across the United States.

Unopened lyophilised vials should be stored at 2–8 °C for short-to-medium term (up to 24 months) or -20 °C for extended multi-year preservation. Once reconstituted in bacteriostatic water or sterile saline, solutions should be kept at 2–8 °C and protected from direct ultraviolet light.

Yes. We accommodate institutional purchase orders (POs), bulk synthesis quantities (grams to kilograms), and custom aliquot fill weights. Please submit your inquiry through our Contact page for a formal price quote and estimated lead time.
