About Citadel Labs

Most peptide vendors will tell you their products are pure. We’d rather show you.
Every batch we sell is independently USA lab tested before it leaves the warehouse.

Every certificate of analysis is published to our public COA library, indexed by lot number, searchable by anyone, and tied to the specific vial in your hand.

No locked PDFs. No “available upon request.” No recycled reports across new batches. The vial you receive comes with the paperwork that proves what’s inside it.

Our Standard

Why Choose Citadel Labs

Every decision we make is built around one principle — you deserve material you can trust.

01
Verified Before It Ships
Every batch is tested for purity, identity, and content at an accredited US laboratory before release. If a batch fails, it does not ship. The failed report is logged and the batch is destroyed or returned. We would rather hold an order than fulfill it with material we cannot stand behind.
02
Sourcing With Discipline
Behind every product is a sourcing process most customers never see. We evaluate suppliers across purity benchmarks, fill-finish consistency, lyophilization quality, and batch-to-batch reliability before a single vial enters our inventory. Our catalog is curated rather than sprawling.
03
Fast & Reliable Shipping
Research moves on its own timeline, and your materials should not be the bottleneck. Every order placed with Citadel Labs ships the next business day, securely packaged and tracked from our facility to your door. No surprises, no extended handling windows.
04
Delivery On Time
Citadel Labs was founded on the conviction that researchers deserve materials they can stake their work on. Our labels, lot numbering, packaging, and fulfillment workflow are engineered to a single standard — applied to every batch, every vial, every order.
