From raw material sourcing to your doorstep, every step of our process is engineered for one outcome: peptides you can trust completely.
These are not aspirations. They are the non-negotiable standards behind every product we ship.
Every product meets our strict 98% minimum purity threshold, with most exceeding 99%. HPLC and mass spectrometry testing confirms molecular identity and detects impurities at parts-per-million levels.
We never self-certify. Janoshik Analytical Laboratory, an internationally recognized testing facility, independently verifies every batch. Results are published openly for customer verification.
All PEPCELL products are manufactured in GMP-compliant facilities within the United States. Domestic production ensures consistent quality control and full regulatory compliance at every stage.
Orders placed before 2 PM EST ship the same business day. Temperature-controlled packaging and expedited carriers ensure your peptides arrive in optimal condition, every time.
A four-stage quality pipeline ensures nothing reaches you unless it meets our exact specifications.
Raw materials from vetted, GMP-certified suppliers
We work exclusively with suppliers who maintain GMP certification and provide their own certificates of analysis. Every raw material is traced back to its origin.
USA-based, GMP-compliant production facilities
Synthesis occurs under strict environmental controls -- temperature, humidity, and particulate levels are monitored continuously. Lyophilization preserves peptide stability.
Independent third-party laboratory analysis
Janoshik Analytical Laboratory performs HPLC purity analysis, mass spectrometry identity confirmation, and sterility testing on every batch before release.
Temperature-controlled, same-day dispatch
Products are packaged with cold chain materials and shipped via expedited carriers. Orders before 2 PM EST ship the same business day to maintain peptide integrity.
We stand behind every product we sell. If your order arrives damaged, is missing documentation, or does not meet our published purity specifications, we will replace it or provide a full refund -- no questions asked.
