qv test 250 pain gone

i was crying on here last week about painful quad shots . i could barely walk . i did some test cyp earlier this year and quads were painless.but this qv test e has been murder so last night i decided to follow some advice from here so i warmed up the test in some hot water in a cup then put i cc in the pin and went for a glute shot and it went in real easy . then i soaked in the hot tub for awhile and this morning no pain at all.. i wonder if this would work for t400 ??? probably not ??
