once i switched to 27g or 29g slin pins i never went back lol. the 25g is like a harpoon compared to those tiny ones. if your lean enough 1/2 inch definitely hits the muscle in the delts no problem and it saves you so much scar tissue over the long run.

honestly man your friend is right. i used 23g and 25g for years and my quads are basically made of leather now because of the scar tissue. i use 27g 1/2" now for everything- even glutes if im lean- and its so much better. it just takes a bit longer to push the oil through.

25g 1" is pretty standard clinic advice but yeah its overkill for delts. i use 29g 1/2 inch slin pins for my daily shots and i barely feel it. just warm the oil up a bit under your armpit or some warm water first and it flows way easier through the tiny needle.

lol your not overthinking it scar tissue is a real bitch after a few years of pinning. i rotate between delts, ventroglutes and lats all with 27g 1/2" needles. definitely add more spots to your rotation though even if you keep the 25g.

i still use 25g for glutes cuz i got a bit of extra cushion back there but for delts i always go with the 29g. your buddy isnt crazy it legit feels like nothing. just be patient when drawing the oil out of the vial it takes forever with those small ones.

the "standard" usually depends on how much oil your moving. if your doing a full cc or more the 25g is fine but if your just doing trt doses or small frequent pins definitely drop down to a 27 or 29. your shoulders will thank you in ten years.

wait until you try 30g lol its like a mosquito bite. only downside is it takes like 2 minutes to push the oil in if its thick. i usually stick to 27g as a middle ground- it’s the sweet spot for me between speed and comfort.

definitely get some 27g 1/2 inchers and try them in your delts. you'll laugh at how much easier it is. the 1" ones are really only necessary for deep glute shots if you arent super shredded.

i wish someone told me about slin pins years ago... i have literal knots in my quads from using 23g needles back in the day. definitely switch to the smaller gauge as soon as you can. your buddy did you a huge favor by showing you those.

just remember if your doing like 2ml or something huge the pressure from a tiny needle might be annoying. but for small trt style pins 1/2 inch 29g is the way to go. i даже pin my lats with them and never had an issue hitting the muscle.

dude your friend is right lol. 25g is like a harpoon compared to an insulin pin. i switched to 29g 1/2" for my delts and glutes years ago and i have way less scar tissue now. it takes a little longer to push the oil through but your shoulders will thank u

honestly 25g isnt the end of the world but if ur pinning multiple times a week it adds up. i use 27g 1/2" for delts and it hits the muscle just fine unless ur carrying a ton of extra bodyfat. definitely start rotating more spots though or u'll get those crunchy knots

lol i remember the first time i saw a 25g needle i thought it was for a horse. you're not overthinking it man... the smaller the hole the less trauma to the tissue. i do 29g slins for everything now- even quads. just gotta be patient with the draw

1/2" is plenty for delts for most guys. if u can see your muscle definition at all u are definitely hitting IM with that length. 25g is basically a "standard" doctors use because they want to get the injection over with fast but for self-pinning go smaller for sure
