I've knocked those that use 25g pins in many threads. I ordered some from GPZ and tried them out this week. Shot test cyp in left quad and deca in the right. Still ended up with the minor sore muscle a day later in my left leg and yet to know about deca soreness since I just did it. I will say its harder to push the oil through and I can't imagine doing a glute shot requiring so much plunger pressure. However it was VERY sweet for these quad injections and probably any other spot injection where dexterity is not a concern. The initial stick was painless and I don't seem to have my quad muscles twitching nearly as much compared to using 22g needles. So I take it back that it can't be done. I do have some 1.5" 23g I will try in glutes that will ideally replace the 22g I have been using. Maybe one of these days I'll get around to trying these 29g slin pins when I have the interest in doing more spot injections where a big needle wouldn't be fun.
