It happens. I've done it twice in a row now and before that not even once for 6 months.
Did it feel gross the first and second time? Thats a feeling I would care not to feel again.
For me I pierced it. It bled and turned into a bad bruise instantly. I also slowed. I’ve heard if you go into the vein you will get super sick and it can incapacitate you super fast. I’m glad I know what it feels like. I think if it happened again I’d pull the needle out and redo with another dose and syringe in a different area.
No just hit a blood vessel. I'm not even close to be able to hit a vein with such short needle.
nasty bruise immediately. It didn’t feel any different than normal for me though 
Thanks, I am now rethinking my whole peptide experience 
I did it once too. Bruise lasted a while.
Same, I use 31g 8mm syringes.
About half of the cartridges have the plunger installed upside down. Some pens don't apply enough force to move them (especially the V2 models).
Good to know. Thanks for the heads up. This is s mounjaropen I use right now. 4 doses then throw in the trash.
Oh, that happened to me too with the Kwikpen. It wasn't quite that quick with those 0.6 ml doses. It's much better now that I make my own pens, no more bumps, and it costs 15€ instead of 250€ a month.
How long did the bruise stay there? I’m guessing since I had a few bruises earned by my sports days and dirt bike riding about 2-3 weeks.
3 weeks at least Bill.
