Dosing Guide LSD is measured in micrograms (μg) A typical LSD microdose is between 8μg and 16μg. “Threshold Dose”, is where you will feel a mild psychedelic effect, is between 20μg and 30μg. ‘Standard Psychedelic Dose’ is 150μg, for most people this is sufficient. A very high psychedelic dose would be 300μg to 480μg. We do not recommend taking more than 480μg. LSD effects will take 60-80 minutes to be felt after dosing. The effects will peak after 2-4 hours and last for about 9-12 hours. After-effects may persist for a few more hours. Storage LSD degrades rapidly in the presence of light and heat, store in a cool, dark place. Do not get the tabs wet.
