The Sokai Difference

Built on science. Driven by possibility.

We provide research-grade peptides to empower scientists, researchers, and innovators — a commitment to quality, transparency, and progress, so the compounds you order are the compounds you actually get.

Our Story →

Deliberate Catalog

Built to cover what a working lab actually needs — established names alongside newer research compounds, not just whatever's easiest to source.

Fewer Vials, More Usable

When a compound comes in multiple concentrations, we stock the higher-strength vial — more usable material per vial, less diluent spent reaching a workable concentration.

Documented, Not Guessed

A certificate of analysis is available on request for any product — batch, purity, and test method included.

No Fine-Print Surprises

No proprietary blends, no vague concentrations — every listing states exactly what's in the vial and how much.

FAQ

Clarity up front.

How is purity actually verified?+

An independent, third-party lab runs HPLC testing on every batch before it's listed — not just our own internal QC. A certificate of analysis is available on request for any product.

What's actually disclosed on a listing?+

Format, vial size, and verified purity are stated on every product page — the same information you'd expect on a specimen label, not marketing copy. Nothing dosing- or administration-related is included; these are research compounds, not consumer products.

Who can purchase from Sokai Sciences?+

Purchasing requires certifying you are 21 years of age or older and acquiring products solely for laboratory research use — independent researchers, labs, universities, and institutions all qualify.

Do you ship domestically or internationally?+

Fulfillment currently ships within the United States. For institutional or bulk international inquiries, reach out through the contact form and we'll follow up directly.

Why does checkout look different from a typical online store?+

Research chemical suppliers are considered high-risk by most card processors, so a standard card checkout isn't available to a business like ours. Payment is handled through a secure crypto-based system instead — you can still pay with a debit or credit card, Apple Pay, or Google Pay, which are automatically converted for you at checkout. It takes a few extra seconds, not a different level of security.

Will my product look exactly like the photos on the site?+

Sokai Sciences is a newer, fast-growing company, and vial labels and packaging are refined as we scale. The compound, purity, and format you order are guaranteed to match the listing — small differences in label design or packaging between what's shown and what arrives are possible and don't affect the product itself.
