Hofmann reagent is the second step in identifying the presence of LSD. This test kit can also identify DMT, 5-MeO-DMT and other tryptamines. Use Ehrlich’s reagent first to make sure you have an indole. Our price is lower than anywhere else because we want these tools to be more widely available. And 100% of our proceeds are distributed to independent, peer-based harm reduction organizations around the country. Questions? Email, call or text. Emanuel always responds quickly.
