I saw this post and had to add this , it seems appropiate here.
I recently did 750mgs of enth and for the very first time I had a reaction similiar to that.
flu like symptoms, felt chilled , painful injection site, wore out down with no energy like being sick but no fever, no runny nose and no upset stomach. lasted for 24 hours the back on my feet again and doing fine
The site is still sore after 5 days, but I know its not the BA or BB in it its a containamination problem
seems more likean impurity, since most tests (test base for suspension excluded) is (*% or so pure leaving a small impurity for the body to try to compensate for.
I went to the doc and he explained to me this is common for some guys who "homebrew or buy powders" since most are pre-made bu companies they remove it and most are underdosed because of this.
Now i dont know the truths to this I am simply speaking from what he explained and how i percieved it.
Never hjad any sysmptoms from prop,susp,enth,or cyp or even omna, or sust or test250 or any others. first time with this enth, however I have heard from a certain place guys are having problems like i mentioned and you have mentioned too.
I believe its a small containamination problem, or even a bacteria, within th test it self that causing it, any similiar reactions with repeated dose?
if not then its simply you if so its your mix, i discarded the whole batch and made some from a different powder it I am not having the same problem.
sterility and such are exactly the same as well as environment too..
so maybe thats it, but I had to let it all out here..Sorry!
