I've been on TRT for a little over 6 months now--200mg/wk test cyp. I recently started T3 to help with my final cut and I upped my test to 400mg/wk to try and maintain as much muscle as I can. Obviously, it would be tough for me to get the extra test from the doc so I got it from a friend who's been on it for quite some time. So it's different test than I get from the doc.

Is it possible for test to cause flu-like symptoms? I'm on my 2nd week of 400mg/wk and both times I injected the test from my friend, I got flu-like symptoms. Last week it lasted for about 2.5 days. This time I injected yesterday afternoon and felt crappy in the evening then felt like crap over night (a fever) and didn't even make it all the way through my workout this morning. Was very light-headed.

Just wondering if that might be causing it. I know T3 can cause these symptoms and I guessed that was what caused it last week but seems strange on the timing and that it happened again this week.

Thanks.
