i was just reading thread on here & someone brought up bb and how some people dont react well with it and get flu like symptoms (at least they believed it to be caused by bb because when they did away w/it, the symptoms also went away)
I have had first hand experience with this.
First time it was from Balkan Nandrolona (UGL Deca) 200mg/ml. I was limping around for several days and had a mild flu like fever symptom.
Right around that time, I also tried Norma Hellas Deca 100mg/ml. Not sure if it was real human grade from Greece (or copy cats made in China or wherever), but I had good results without the excruciating pain and fever.
Then, I did Geneza Pharm Test Prop 100 (UGL). My strength gain was through the roof but so was the pain, which started around five hours post injection and last for nearly a week. The flu symptom was worse than the UGL Deca.
I didn't know what caused it, but I was pretty sure it was
1. not an infection, because the spot where I injected was not swelling nor red in color.
2. not a nerve that was pinned, because when I pinned, I felt no pain at all for the first five hours. (If it were a nerve that was pinned, I should have felt it right away.)
All I felt was this deep, constant, salt-on-an-open-wound kind of pain. I felt it around a small area on hip bones and joints (on the side that was pinned).
The day after, I went on the Geneza sponsored board and made a complaint, and a lot of the bros (and possible shills) blamed it on:
"virgin muscles"
"prop always hurt, bro"
"no pain no gain"
"you'll get used to it"
Of course, I didn't buy all that bullshit, so I went and Googled this topic and found from research articles and from other people's experiences that Benzyl Alcohol (BA) and Benzyl Benzoate (BB) were the likely culprits.
(If you're interested, I could link you to the research articles).
After that, I decided to test this theory out by evaporating the BA/BB through baking:
BENZYL ALCOHOL
Boiling point 205 °C, 401 °F
Flash point (Evaporation) 93 °C (199 °F)
BENZYL BENZOATE
Boiling point 323 °C, 596 K, 613 °F
Flash point (Evaporation) 158 °C (316 °F)
This SIGNIFICANTLY reduced the post injection pain to the point where I was no longer felt "crippled" after each shot.
But even with all this said, you should not take what's in the research articles and my words for it. TEST IT yourself! If you're doing your own homebrew, what you can do is make two small batches (10ml or so each). Then on one batch, use ba/bb as you or other people normally do. Then on another batch, don't use the ba/bb. And then just see the difference between the two.
