Lately, I've been having a hard time achieving a successful pin. I'm taking 80 mg twice a week of test etho for TRT. I use a 1mL syringe and a 23g 1” needle. Whether it's my glutes, outer thigh or delta, I'm left with some kind of inflammation. Usually, it's a hard swelling that's slightly sensitive to the touch and warm. I'm not going to name the brand but I've tried the test cyp as well and same results. I have a hard time believing that I'm doing something wrong because I've been taking this for years. However, maybe I am and someone can share some feedback. I tried sub inj as well and that went very bad. Would've preferred that way due to frequency. Welt lasted 3-4 weeks. Is there a specific carrier oil that I should consider? Maybe switch brands all together? I'm happy to pay for a quality product if I know it will not lead to. Should I switch tools? Thanks.
