Company Overview

The company operates as a B2B chemical reagent supplier targeting research buyers, distributors, and med spas with bulk catalog offerings and white-label services. The site states that it provides over 50 catalog compounds across multiple categories, alongside custom production and private-label packaging options. Additionally, the platform publishes compound guides and procurement information for prospective business clients.

The site states that every production run undergoes independent third-party HPLC/MS testing, with per-lot certificates of analysis available as paid add-ons. Orders require a minimum of 100 vials (mix and match in kits of 10), and purchases are invoiced offline via wire, ACH, Zelle, or credit card after quote submission. Fulfillment is handled from a Costa Mesa, California facility with domestic shipping and overnight options available. Buyers would still need to inquire directly about exact per-compound pricing structures and custom volume lead times.

Pros
  • Third-party HPLC/MS testing conducted on every production batch.
  • In-house white-label design, printing, and application services.
  • US-based fulfillment with lot-tracked warehousing and domestic shipping.
Considerations
  • Public per-vial pricing requires a requested quote rather than instant web checkout.
  • Certificates of analysis are offered as a paid add-on rather than standard inclusion.
  • The specific name of the contract analytical testing laboratory is unstated on the site.
