Always wondered why but never actually looked into why. I found this part of an article about what causes ''test flu''.
'Sustanon flu' or 'sus flu' is a fairly common occurrence when using testosterone. The problem has been given this name by some users who experience flu-like symptoms upon commencing a testosterone cycle. It's worth noting that this problem is primarily associated with short esterified testosterones such as Propionate (including Sustanon which include a Prop/Phenylprop ester), though is possible in reality from any testosterone ester. Although there are varying opinions which suggest a cause for this issue, the properties and effects of testosterone metabolite Etiocholanone make it appear particularly plausible. Etiocholanone is a pyrogen and elevations in circulatory levels are associated with feverish effects. Propionate as we know is a fast acting ester resulting in a rapid elevation in testosterone and thus etiocholanone levels. It's certainly possible that this rapid increase results in some users experiencing flu-like symptoms during the early stages of a cycle.
