Reaction to Sustanon?

Pharma / TRT
1

I have heard of reactions at the injection site with Sustanon (and other forms of test). I have also heard of mild flu-like symptoms after injection. Can anyone shed some light on what causes this reaction, and if some forms of test, like enanthate, are less prone to being reactive at the injection-site?

Thanks.

From what I’ve read, the reaction is caused by the addition of Propionate ester in the sustanon. I’ve noticed these side effects from sustanon, but did not notice them when I took enathate, cypionate etc.

I have heard the same about proprionate. Thanks.
