Im on trt and have ran multiple cycles Over the years and have never experienced anything like this. Last month I ran a bottle of primo and didn’t really notice much as expected then picked up another bottle as well as some NPP and injected them both in the same syringe & within a minute of injecting I starting feeling a sensation in my lungs along with dry mouth. Right away I thought I may have hit a vein so I made sure to backfill the syringe next time and sure enough the same thing happened again. I started to get dry mouth & My lungs felt like they were being tickled when I would talk or breathe. The best way to explain the sensation is the feeling of holding back a cough. I will say tho the second time didn’t last as long. I take it that it has to do something with the NPP because it’s the only new compound I’ve added since noticing this and it’s immediately after injecting. Does anyone know what this may be? Please help
