What was found in tested Heart blotters?

Heart blotter reports can differ in artwork, batch and strength. Recorded samples are most often blue (50%), grey (17%) and pink (17%). Here you can compare independent laboratory results for 12 photographed samples tested between 2025-09-11 and 2026-03-20 and listed in source records under names such as: Heart, heart, coeur, corazon, herz. LSD is dosed in micrograms and the solution is not always spread evenly across a sheet, so two tabs cut from the same sheet can differ.

Use the reports below to compare detected substances, dates, locations and source laboratories for tested samples carrying the Heart design. A blotter’s artwork cannot identify what is on it. Sheets sold as LSD have been found carrying NBOMe compounds, which are active at similar amounts but far more dangerous.

Dosing varies within a single sheet, because the liquid is not always applied evenly. A tab that looks identical to the last one can carry a different amount.
