How are you getting an oil based T-cyp through a 29 gauge needle without major effort? Also, since you are using a 5/8 ths length needle, can I assume you are ultra lean, have very thin fat layer on your thigh or you just inject into the fat?
I'm not asking to be sarcastic, I feel like maybe I could go back to injections if it was that convenient and worked. If you read the only post I've posted here, I have been on TRT for 20 years and am sick, sick , sick of injections. I've hit nerves, I've hit blood vessles (granted not common, but over 20 years and with lots of scaring in my back side, it's inevitable). But I use a 27 Guage 1" and press it to the hub because I'm always concerned about getting it into the muscle. I've tried switching to my thighs but get the same issues and when you hit a nerve, your whole muscle jolts, blood vessels just hurt more than usual.
Anyway, would love to get the technicals on your injections. Do you use T-cyp or are you using a water based T? Are you injecting into the fat layer or are you able to get below it with a 5/8ths length needle? If you're using oil based, how do you grip the plunger so you can get enough force to push it through? Also, if you pre-load the syringes, how many do you pre-load, are you worried at all about contamination (I'm a microbiologist so I have real issues with sanitation - I've seen sterilized buffered water opened only once - with sterile technique- in a lab grow mold in less than a month).
