So I recently purchased Tesamorelin from PS and have developed a lump after sub-q injection. The bacwater was new and I was sure to wipe the bacwater and Tesamorelin vial tops as well as the injection site on my stomach prior to administration. I suspended the Tesa in 0.4 ml and injected near my stomach with a 31g slin pin. Shortly after injecting, I got a chemical burning sensation (no itching) and redness around the injection site. That resolved over the course of a couple hours. Over the past few days the the soreness has decreased but I still have a lump at the site. The lump is a bit sore when rubbed and it’s been 6 days since the sub-q injection. Any idea how long this lump will persist? Is it a common occurrence? Any advice is much appreciated. Thanks guys.
