If it hurts in the glute it might cripple your quad!!
FYI I am not experienced nor an expert like the mods on here, nor as hard core as DYG yikes with that much volume in a quad...but tons and tons of folks on HRT use only 29g 1/2" needles on quads for Test....including me...with no issues, its works as labs indicate as well no loss in performance. I do 27 or 29g half inch in quads for Test, but when doing blasts I use 23-25g 1" for my glutes with Primo and Mast. I am relatively low BF. Quads to me are a hundred times more sensitive than glutes for pinning.
