US-manufactured, third-party tested, and shipped from our domestic facilities. No overseas black boxes. No mystery compounds. Just pharmaceutical-grade peptides backed by real COAs.
We started Caliber because we were tired of the same thing you were — overseas peptides with questionable purity, no transparency, and zero accountability.
Our synthesis labs are in Nevada and California — 100% domestic. You can verify us. We're real people, in real facilities, making real peptides.
Every single batch is independently tested by a third-party lab. We publish Certificates of Analysis so you can verify purity and identity before you buy.
We don't ship anything under 98% purity — and our average batch comes in at 99.2%+. HPLC and mass spectrometry testing on every batch ensures you get exactly what the label says.
Temperature-sensitive peptides ship with cold packs in insulated packaging. We don't cut corners on the one thing that ruins product quality.

Full vertical control. No middlemen. No mystery suppliers. Here's exactly how your peptides get made.
Solid-phase peptide synthesis in our Nevada and California labs using pharmaceutical-grade amino acids and reagents.
HPLC purification to 98%+ purity minimum, with an average of 99.2%+. We don't release batches that don't meet our standard.
Third-party lab verification via HPLC and mass spectrometry. COA generated for every batch.
Lyophilized, sealed, and shipped cold-chain from our facility. Tracking on every package.
"Finally found a supplier I don't have to second-guess. The COAs are legit, the purity is consistent, and it ships from an actual US address."
"I've been burned by overseas vendors twice. Switched to Caliber 6 months ago and haven't looked back. Night and day difference in quality."
"The cold-chain shipping alone tells you these guys take it seriously. Product arrived perfect. BPC was exactly as described on the COA."
All of our peptides are synthesized and purified in our own laboratories in Nevada and California. We do not outsource manufacturing overseas. Our entire supply chain — from raw amino acids to finished product — is managed domestically across our US-based facilities.
Every batch ships with a Certificate of Analysis (COA) showing HPLC purity data and mass spectrometry confirmation. COAs are also available on each product page before you purchase. We use independent third-party labs for all testing.
Orders placed before 2PM PST ship the same business day. Temperature-sensitive peptides ship with cold packs in insulated packaging. All orders include tracking. Free shipping on orders over $150.
