Too much milk.

The lads stood in the decontamination bay and showered each other down.

Washing off as much of the chemicals as they could as it slowly transformed each man into a woman.

Whilst management frantically tried to get everything under control and report what had happened to the men to the local authority who sent for a government HazMat team to take over.

They had no idea that their formula would do this to men. 

It was only a breastmilk substitute high in vitamins and minerals & was designed to mimic actual breast milk.

They had no idea what else the formula would do to the former men.

So they decided to keep them separated from everybody else until the hazmat team deemed it safe to release them.

Which did not go down well with the transformed men who were highly emotional & pissed off with what had happened to them to be detained like this.
