I video logged my progress throughout my entire first cycle with each pin. It's funny to watch them over again.
The first one is 20mins long and was edited down lol.

It must have taken me an hour to prepare for the first pin. I remember the process;

Taking a shower
Laying out gear and equipment
Washing my hands
Cleaning the site with alcohol
Cleaning the gear top with alcohol
Drawing a grid
Filing up with a 23g then switching to the 25g to pin with
Cleaning the site again
SLOWLY pinning, double checking with aspirating then pushing the gear in slowly
Waiting for the tiny tiny blood dot to dry up a bit to clean the site again
Taking another hot shower thinking it would help keep pip to a min.

It must have worked because I remember thinking...'That was easy', all the way until the next pin day.
No bruise, tiny amount of pip. I didn't even feel the needle pierce the skin (I was watching TV to distract myself from the pain). I remember looking down, only to see the needle buried in my quad already.

I also remember my fourth pin on the other quad. PIP showed up the next day so bad I was limping for 3 days.

BTW, I have yet to ever get a bruise from any pins. Currently on my third cycle.

My story goes back before the Internet existed. My gear guy sold me Test Cyp and Test suspension and only gave me ONE needle. Being that I didn't have any other avenue to source some pins I took his advice and RE-USED the same 21g pin over and over for about 5 weeks to complete the cycle. He instructed me to clean the pin with alcohol after each use...which is what I did. I think I was pinning about 4 times a week with the same needle! By the end of the first week, ithe pin was so dull that it was HELL just breaking the skin. By the end of the cycle it was like pushing a dull nail into my ass!

Pushed it in and depressed. Didn't aspirated, no bubble, wasn't thinking at all, I was so nervous. I used to be an addict who told myself that atleast I would never shoot up, and look at me now! Awesome!

Pure fear. I think I must've spent at least an hour going back and forth trying to make sure I followed procedures properly, getting ready to do it and then getting up and working up the guts again to try to do it. I finally got sick of myself, and after marking off a spot where I thought there was no vein, took a deep breath and injected into the quad. Turned out to be not bad at all...but then I found out it's the day after you really have to deal with because of virgin muscles. Even then not bad. Course now, like quite a few folks, I look forward to pinning.

Just so you know had the same issues three weeks ago. Pinning w 23g with 11/2 in the glutes with 250 test e twice a week. First time scared shaking in the right side was not bad just let a little out to lubricate the needle second time was in the left side a little hard being I am right handed had a little bit of a bruise.. Now in third week only time I have pip is when I touch the spot like a bruise

Got a pretty bad bruise the first time i pinned my glute because my hand wouldn't stop shaking lol

Already in here. Just type pinning in the search.
