Company Overview

The company operates as a Houston-based supplier of research peptides, targeting both individual researchers and wholesale buyers including clinics, resellers, and research organizations. The site states that it offers research compounds categorized by application areas. Additionally, the company maintains a public COA library for batch tracking.

The site states that every batch includes third-party testing documentation covering HPLC purity, mass spectrometry, and endotoxin levels, alongside measured milligram content on vial labels. Purchasing is conducted via invoice-based ordering or through an application-gated wholesale portal, with orders confirmed before 3 PM CST shipping the same day from Houston. Buyers would still need to inquire directly regarding specific minimum order quantities and customized wholesale pricing.

Pros
  • Batch-specific third-party testing documentation covering HPLC, mass spectrometry, and endotoxin panels included with orders.
  • Publicly searchable COA library indexed by unique batch ID.
  • Same-day shipping from Houston for orders confirmed before 3 PM CST.
Considerations
  • Minimum order quantities are not publicly stated.
  • Wholesale access requires completion of a vetting application.
  • Pricing for wholesale orders is quoted individually per account rather than published publicly.
