What is HPLC purity testing?

High-Performance Liquid Chromatography (HPLC) is the gold standard for measuring peptide purity. 98%+ is pharmaceutical grade, 95%+ is research grade.

How are lab tests verified on Peptigrity?

Lab tests are submitted by community members with original certificates from accredited third-party laboratories. Each submission is reviewed before publication.

Are testing laboratories affiliated with Peptigrity?

No. There is no business relationship or payment from any testing laboratory listed on the platform.

How do I submit my test results?

Registered users can submit lab test results through the submission form. You need the original certificate of analysis from the testing laboratory.

peptidetest

USA · USA

Customer-facing peptide testing service that brokers HPLC purity and mass spectrometry analysis through a Michigan-based partner lab whose CoAs are delivered via the TrustPointe LIMS system — strongly suggesting TrustPointe Analytics is the actual analytical lab. Distinctive feature: group testing portal for cost-splitting.

No ISO/IEC 17025 accreditation on file

peptidetest is not currently listed as ISO/IEC 17025 accredited — the international standard for testing and calibration laboratories. This is not unusual in the peptide testing market (most listed labs lack it). Accredited results carry more regulatory weight in formal contexts. Read about lab accreditation standards →

About peptidetest

US-based peptide testing service in Michigan with USP/NF-validated analytical methods, group testing portal for cost-splitting, and lab supply shop for sample preparation.

What sets peptidetest apart

✓Group testing portal for cost-splitting. Researchers can pool vials from the same batch and share testing costs through a dedicated portal — the only lab service in Peptigrity's index publicly offering a structured group-buy model. Reduces per-vial cost by 30–50% versus standard individual submission.
✓USP <1225> validated HPLC methodology — methods are validated against the United States Pharmacopeia compendial chapter governing analytical method validation.
✓TrustPointe LIMS CoA delivery — CoAs are issued and verifiable through the TrustPointe LIMS system, connecting Peptide Test to the same Michigan-based analytical infrastructure as TrustPointe Analytics.
✓Transparent published pricing — $200 initial vial, $120 per additional vial for batch-variance testing. Pricing is published on the lab's product pages, unusual in the peptide testing market.

Honest disclosures

Peptide Test is a service brand, not an independent laboratory. The actual analytical testing is performed by a Michigan-based partner lab whose CoAs are issued through the TrustPointe LIMS system — almost certainly TrustPointe Analytics. Buyers should understand they are commissioning testing from TrustPointe with a different customer-facing wrapper, not from a separate analytical lab.
No publicly listed ISO/IEC 17025 accreditation. Standard for the peptide testing market.
0 tests currently published in Peptigrity's lab test database. CoAs issued under the Peptide Test brand may be counted separately from TrustPointe Analytics submissions in the index.
Group-buy testing assumes all participating vials are from the same batch and identically labeled; mismatched vials require separate testing at standard pricing.
Batch-variance pricing distinguishes "non-differentiated" results ($120/additional vial — results combined into a single CoA) from "differentiated" results ($135/additional vial — results linked to individual vials). Choose the right tier for the question being answered.
