Lmfao.. yeah. I guess.. dont mind me last night

I use the same method basically. Have got some mast that crashed on me when delivered in winter months

I heat up some water in a coffee in the microwave, maybe 1-1 1/2 minutes. Then I put the vial in but be careful not to cover the top of the vial. Let it sit for about 2 mins and you're in business.

We are similar leanness and have thought about it

I back fill then warm the pin on a coffee warmer. Shoots perfect.

Whats the difference between slin pins and tuberculins? All the pictures I googled, they look the same? The only difference is the markings?

Aight y’all tried this for the first time. Overall shot was easier with the smaller needle and less pain breaking the skin.

However I feel like I wasted a good bit of oil, nearly .2 of the 1cc to get rid of the large air bubble after backloading the pin.

Anyone know a good way around this?
