Test enanthate now gives a red hot lump after every injection, no matter what brand I use. Never used to before

[peptidesupplier]

So I’ve been using testosterone enanthate for about 20 years. On and off in the beginning but now I’m TRT for life. Testosterone Enanthate used to never give me problems, no swelling, no redness, no PIP. But these last few years I’ve noticed after every Test E injection, I get a red hot swollen lump at the injection site. No matter what brand and concentration I use. Has anyone else ever experienced this and maybe have some knowledge about it? Could I be developing an allergy to that ester?

We have Testosterone Enanthate 250/300/400mg concentrations if you're interested.
