The BEST thing I've found to avoid knots and pip is to pin in a freshly trained muscle that is still pumped... That won't work so well for tne, but you can try pinning it warm, into a muscle you won't be training after pinning, and pump it up a little(ex. Pump shoulder up and pin it for doing pre leg workout... Walk up several flights of stairs or do sissy squats at home to pump glutes/quads, then pin that pre upper body workout...). Pinning into a blood laden muscle makes a TON of difference!!! I pin 300-400mg comps routinely, and avoid pip this way(and, my chef is DAMN good at making smooth shit! Lol)
