Such a fake was spread by Russian propaganda. The Center for Strategic Communications and Information Security notes that reports of the release of heptyl began to apply after the enemy attack on "Pivdenmash" in the Dnipro. But all of them are fakes.

On July 15, in Dnipro, the Russians hit the Southern Machine-Building Plant and the street nearby with six rockets.

The Center for Strategic Communications said that the Russians could have caused the leak of heptyl and carried out a terrorist attack comparable in scale to a nuclear disaster.

However, even at the beginning of Russia's full-scale war against Ukraine, heptyl and its derivatives were urgently disposed of in Pivdenmash, the local ground defense headquarters reported.

"There was no leak. And rumors are spread by enemies to spread panic. Heptyl is a hazardous component of rocket fuel for humans," the Center said in a statement.
