Which test ester is most commonly responsible for allergic reactions/flu?

[Dr.X]

Which test (susp, prop, enan, cyp, etc) have you had reactions to in the past? Although individual differences may exist, it seems likely that one or two different tests may be mainly responsible for allergic reaction/flu-like symptoms.
I ask this because I get sust/omna flu bad and was trying to figure out which component is doing it. Of particular value would be responses from people that have 1. Gotten sust flu, and 2. used different single-ester tests

Only ever heard of Sus flu mate. Ive dont prop with no problems at all. Never heard of any such reactions with cyp or enanthate either.

I got test flu from cyp the first time I used it in a cycle. Haven't run test again until my current cycle, the first shot of which (enanthate) was on last Tuesday -- no flu yet... *fingers crossed*

i am going to bump this becasue i have been courious about what causes the sust-flu.

Perhaps Huck can answer this question.

 

[THeMaCHinE]

My understanding is that it's not specific to sust, it's a test (in general) phenomenon; there were posts on this a long time ago. Maybe I can dig one of them up...

 

[Dr.X]

I get a very reproduceable sust flu, with symptoms starting 8-10hrs post-injection and lasting for another 10-12h. One day later I feel fine again.
I've taken cyp alone with no sides or flu-like symptoms of any sort.
