Community Science Challenge!
Challenge: Is your ketamine pure R or S?
We are offering a free analysis to anyone who sends in a sample which turns out to be either pure S‑ketamine or pure R‑ketamine! To participate, simply send in your sample for testing with the “enantiomer” analysis. We will then test it and if the sample is at least 90% S‑ketamine or 90% R‑ketamine, we will contact you and send you a free analysis coupon for your next sample.
As part of a formal scientific study to assess ketamine from unregulated sources, your submission not only gives you a chance to win a free analysis but also contributes to research that will benefit public health and improve understanding of the supply.
What does “enantiopure” mean and what is a racemic mixture?
Ketamine, like many molecules with an asymmetric carbon, exists in two “mirror” forms called enantiomers: R‑ketamine and S‑ketamine. They are chemically identical except for spatial configuration—like left and right hands—but interact differently with the body, affecting subjective and therapeutic profiles.
A racemic sample contains a 50/50 mix of both enantiomers. This form is most common in medical and gray‑market contexts.
Enantiopure ketamine contains only one enantiomer—usually S‑ketamine, known for potent anesthetic effects (Hempelmann & Kuhn, 1997); R‑ketamine shows longer‑lasting antidepressant effects with fewer side effects (Jelen et al., 2020).
How to participate:
- Submit your sample for analysis by choosing the enantiomer analysis on our shop page.
- If your result shows ≥90% enantiopurity, you win a free analysis coupon for your next sample.
