You don't remember all the experiments conducted by Ilya Ivanov? The Soviets could have easily kept his work going in secret without him

Well yeah, but where the fuck are all of the supersoldiers then? I'm honestly not even sure we're genetically compatible enough for viable offspring. El Pombero (South America smol bigfoot) are told to produce ugly, sick offspring with human females that dies quickly

Though they could have tried. Then again, stuff like Tuskegee Syphilis Study were declassified and supposedly fit in the same timeframe.

It's possible that they have tried some bullshit with artificially inseminating wives of military men during check-ups. But why did HIV first massively affect male gays and drug users? I'd rather believe this was a weapon against poor to keep growing population of lower classes in 1st world under high retention.
