Is DHB cough a thing? Similar to Tren cough, but not as bad.. at least for me.

I started to run some DHB a few month ago, but came down with covid and aborted mission shortly after. A few times, I got a cough shortly after injecting. Same taste in the mouth as Tren, and same bad cough that lasted for about 5 minutes. Have a friend that started running DHB a few weeks ago, and he said the same thing is happening to him.

Thoughts or experiences?
