AT Lab Sourcing connects research organizations, qualified laboratories and independent researchers with verified, high purity USA lyophilized peptide products — filled and finished domestically in ISO 5 Class 100 clean rooms.
AT Lab Sourcing is a B2B wholesale distributor specializing in lyophilized peptides for research organizations and qualified laboratories that demand verified quality and reliable supply chains.
We bridge the gap between CGMP Compliant US lyophilizing facilities and the professional organizations that depend on consistent, documented product performance.
Every step of the finishing process happens domestically, under controlled conditions.
Raw active pharmaceutical ingredient is received and quarantined. Identity and purity are confirmed via HPLC and mass spectrometry before any production begins.
API is formulated to exact concentration under sterile conditions. Every batch is prepared using validated protocols in our ISO 5 Class 100 controlled environment.
Product is freeze-dried in our domestic ISO 5 Class 100 clean room. This removes moisture while preserving full peptide integrity — extending shelf life and maintaining potency.
We operate exclusively in the wholesale channel. That focus means better access, deeper expertise, and a sourcing partner who understands your requirements.
Every product line is sourced from manufacturers with documented purity verification. Express shipping available on qualifying orders.
USA-first sourcing with international alternatives when you need expanded access or volume pricing flexibility.
Competitive tiered pricing structured for the procurement cycles of professional B2B organizations.
Direct access to our sourcing team for inquiries, custom requests, and order coordination — no call centers.
