Clumpy Winstrol

My friend asked me a question I couldnt answer:
he was having a problem drawing winny into a pin, when he did it came out clumpy and took like 5 min to fill 1cc. When he finally shot it he said it hurt like a mofo. Not sure what brand he has. Anyone have any comments?

Winnie is a suspension,that means that the particles are like snowflakes floating around in the liquid. 1st thing,make sure he shakes the bottle really well before drawing up. Different brands have different sized flakes in their suspension. I used some Australian Winnie and it must have been hugh frosted flake sized clumps. It would even clog a 20ga pin. I finally gave up and just drank the shit.
