I pinned my quads 100x. Sometimes as much as 3ml. Then one day I pinned 1ml of Npp/Tpp 150/150. My leg swelled to double it’s size and my foot looked like a rubber glove full of jello. That was the last time I did it. Three days later Dave Palumbo posted a rant about thigh injections saying that everything can be fine then...one day.....
A swollen glute is tough enough to deal with. A swollen leg? Miserable!

Mine took over a week to clear.
