slin pin the shit or try 25g needles, always rotate, 7 days minimum in between site areas, your better off doing less oil more pins, so instead of pinning 3 ml into 1 muscle, pin 1.5ml into 2 muscles, essentially the carriers are cooking your muscles from the inside, think of aero chocolate, the inside is bubbly and aerated, this is similar to what happens when we pin, so the more oil= more carrier= more irritation=more healing= more chance of scar tissue build up, also dont forget the fascia, stretching should be apart of daily life, that shit gets scrunched and creased, its the same texture as chicken skin, stretching somewhat keeps it uncreased etc etc, get blood into the muscle you are about to pin, heat the oil up to body temp, and have a warm shower before you pin also, massaging the area works for some, the problem is if you pin and come very close to a vein/ vessel etc etc, massaging can actually cause more damage, any pip always look for heat, not cold, remember gear crystalises in the muscle, heat helps melting etc etc. good luck.

Try glutes. Even after 20+ yrs,, I can do quads,,,Im too veiny and either hit a nerve a knick a vein.

Aspirate? I've hit vessels before and had blood shoot out a few feet
