Gear Stored In PLASTIC

Hi guys, my penpal in China sent my some 2x 500ml containers of t prop @ 100mg/ml & 2x 500ml containers of tren ace @ 50mg/ml.
The containers are plastic (PET1) (standard drinks bottle containers)…
18% BB, 2% BA
My question is; the gear is stored in them for 2weeks, with 90ml BB & 10ml BA in each container … Would it have corroded any plastic and can i use it safely after filtering ? (i will be filtering with .22 millpore steritop)

Alcohols dissociate organic materials, so you will have polymer molecules floating around in your gear. Sorry, don’t know what your Chinese friend was thinking.
