4mm or 8mm needle? Doc's got me questioning!

Hey everyone, I've been doing great with 4mm needles for my injections, but my physician friend thinks 8mm is a better choice. Is there any real reason to change what's working? I trust their opinion, but I'm curious about the logic.
 
I'm not convinced the length matters that much, as long as you're getting it into the subcutaneous layer. If anything, I'd worry about accidentally hitting muscle if you're injecting in areas like your thigh or arm.
 
I think 4mm is usually sufficient. However, some people move away from 4mm as they find them tricky and can lead to injection site reactions. I've switched to 6mm for most peptides and 8mm for very shallow IM injections into my deltoids and ventrogluteal area. I'm pretty lean now, so it works well.
 
I'm experimenting with 4mm needles to see if the smaller gauge is truly painless. I've had some minor issues compared to using 6mm needles. They do work fine, but you have to make sure you're injecting deeply enough and keeping the needle steady. I use 8mm for GHK-CU to help minimize ISRs.
 
That's what I was thinking. I'm fairly lean now, so an 8mm needle might actually hit muscle. I'll probably stick with 4mm or maybe 6mm max.
 
I heard that many people find the 8mm option more comfortable, especially if they've had issues with localized reactions or painful injections. The reason given was that it delivers the medication beneath the mast cell layer, which causes the reactions and discomfort. Pinching the skin before injecting can also help avoid accidentally going into the muscle.
 
GHK-Cu, L-Carnitine, MOTs-c, and testosterone can sometimes cause discomfort. Also, 5-amino-1 can be problematic, at least when starting out.
 
I was really scared to start injecting myself. I put it off for almost a year! I was using oral meds at first but then I plateaued and had to really focus on counting calories. It's been a constant struggle with weight, but I finally decided to face my fears. Turns out, the needles are super tiny! Injecting myself was still scary at first, but it's been so worth it!
 
For anyone who's worried about the injections hurting, try using an ice pack to numb the area beforehand. Some people say it doesn't hurt at all, but I don't believe them! 😅
 
Hey, for those using BPC-157, is it important to inject near the injury site? I'm recovering from rotator cuff surgery (it's brutal, like they say!) and only have use of one arm right now. I'm injecting sub-q in my belly fat since it's easy to reach, but I'm wondering if I should be doing it differently.
 
I've heard that micro-dosing close to an injury can help the area absorb more BPC-157. It will eventually go systemic, but I've had better results micro-dosing locally. No concrete evidence either way, though.

What do you mean by micro-dosing, like what does that look like?
