This document, from the CIA's MKUltra program, details experiments comparing the effects of a new LSD sample (LSD-25-61) with older LSD stocks, finding the new material to be at least as active.
This is one record. The archive holds the rest — ask it anything across the MKUltra files and every answer is cited to the page.

The image shows a graphic with text overlayed. On the left, there's an illustration of a vault door with gears and a dial, suggesting security and hidden information. The text at the top reads "THE BLACK VAULT" in a stylized font. Below this, explanatory text details that the document was obtained from The Black Vault, an online database of declassified government documents, specifically from the MKULTRA/Mind Control Collection. The text also provides a URL for online access to the collection. There are no photographs, handwritten annotations, official stamps, forms, diagrams, tables, redactions, or visual evidence of experimental procedures present.
The document is a typewritten letter on official letterhead from the National Institute of Health and the Addiction Research Center. Several handwritten annotations are present, including circled numbers like "54" and "(6)(3)". There are also some illegible handwritten marks and scribbles in the margins. The document appears to discuss experiments involving LSD. One area of text is partially redacted. No photographs, forms, diagrams, or tables are visible, nor is there any direct visual evidence of experimental procedures, equipment, or facilities.

The document appears to be a report or research paper containing a table of experimental data. The table presents measurements for different physiological responses like "Knee Jerk," "Pupils," "Blood Pressure," "Questions," and "Clinical Grade" across various conditions, including "Placebo," "25 mcgm New LSD," "60 mcgm New LSD," and "60 mcgm Old LSD."
There are no photographs or diagrams present. The document includes a handwritten annotation at the bottom right corner: "A-195." The page also features a title "COMPARISON OF NEW AND OLD LSD" and a subtitle "Experiment No. I."
The text seems to be typed, with some handwritten modifications or additions, particularly in the "Clinical Grade" row where a symbol appears next to "0". Additionally, there are some faint lines or marks that might indicate page divisions or edits, and some scattered black dots that could be ink smudges or dust.
This page displays a typed table comparing "NEW AND OLD LSD" as part of an "Experiment No. 2." The table presents numerical data under "60 mcgm Old LSD" and "60 mcgm New LSD" for measures including "Knee Jerk," "Pupils," "Blood Pressure," "Questions," and "Clinical Grade." Below the table, a handwritten note indicates "Averages of 5 negro subjects." Another handwritten annotation in the bottom right corner reads "A-194." The page also contains some smudges and occasional stray marks that might be from the original document or the scanning process. There are no images of people, locations, equipment, or facilities, nor any official stamps or formal forms.
This document presents a table comparing results from an experiment involving "NEW AND OLD LSD." The table has three columns: "MEASURE," "60 mcg New LSD," and "60 mcg Old LSD." Under "MEASURE," there are two rows: "Questions" and "Clinical Grade." The corresponding entries are "152" for Questions under New LSD and "131" under Old LSD, and "1.75" for Clinical Grade under New LSD and "1.5" under Old LSD. There are some handwritten annotations, including "A193" in the bottom right corner. The document appears to be typewritten with some imperfections due to the age and nature of the document.
