Shot of sustanon 250 (0.5ml) caused illness?

Tried a shot of sustanon 250 for TRT. Only 1/2 ml as I know I have a delicate endocrine system after the crash. Anyone taken a shot (injection) and experienced sickness like feeling (nausea) stomach discomfort, fatigue and a chemical smell on the breath? My girlfriend has told me she can smell quite a strong smell of “nail polish remover” which when researched links to diabetes! Yet before this 1/2 ml (0.5ml) I was fine!

Anyone heard of this before?

250mg likely caused an estrogen surge.

I take about 80mg of Sustanon and .125mg of Letrozole DAILY to control estrogen.
