About Darkside Labs

The supplier we wanted to buy from.

Darkside Labs exists for researchers tired of guessing. Every compound is documented, every price is on the page, and every order is handled with the discretion serious work deserves.

(01)Principles

Four principles.

01

Transparency first

Batch numbers, certificates and pricing are public. If we can't document it, we don't claim it.

02

Verified, not assumed

Batches are analysed by independent laboratories before release, and results are tied to the vial in your hands.

03

Research, responsibly

We sell to qualified researchers for laboratory use only, and we decline orders that suggest otherwise.

04

Built for the bench

Lyophilized, sterile-sealed vials, packed with stability in mind and shipped in plain packaging with tracking.

(02)Process

From synthesis to your bench.

Five stages every batch passes through before it ships.

  1. 01

    Sourcing

    Compounds are produced to specification by established synthesis partners.

  2. 02

    Fill & lyophilize

    Material is filled to a verified mass, freeze-dried for stability and sealed under sterile conditions.

  3. 03

    Independent testing

    Samples from each batch go to a third-party laboratory for purity and identity analysis.

  4. 04

    Release & publish

    Batches that meet specification are released, and their COA is published in our library.

  5. 05

    Discreet fulfilment

    Orders ship quickly in unbranded packaging with tracking from our facility to your lab.
