Do you mean are there any records which show the project existed? Or do you mean did any of the many experiments yield results?

If your question is the former, when Richard Nixon forced CIA Director Richard Helms to resign in 1973, Helms ordered all documentation on MKULTRA to be destroyed. In 1975, seven boxes of financial records were found, which led Congress to investigate the program in 1977 through a select committee. That committee's findings are available. Here are a few sources you may find helpful:

If your question is did MKULTRA yield results, the answer is not really. There were many different programs under the umbrella of MKULTRA (and later MKSEARCH) with many different aims. I'd suggest consulting the works above.
