You didn't/don't need any BB at all with nandrolone decanoate, boldenone undecylenate or testosterone enanthate. 500mg isn't a problem when it comes to solubility, but can easily be a problem when it comes to pain.

You dont need it, but damn at those concentrations, the solution is thick as hell. If you are trying to squeeze 500mg/ml test enan thru a 25 gauge pin with only 2% ba, it will take forever.. I add the bb just to thin it out. 500mg/ml test enan was damn painful for me, crippling pain and knots.

Now lets get back to the point. Max concentrations made for whatever gear you ever made that included no pain to minimal pain.

Don't get me wrong; I'm not advocating injecting 500mg/mL. I put up with it for a while, but I finally had enough of the muscle soreness; I'd much rather just inject more frequently than constantly have a sore ass.

What I now do is I either mix my 500mg/mL test enan with other gear in the syringe, or I mix it with sterile oil in the syringe, or I do both.

I use grape seed oil, which is pretty thin. Drawing it up isn't much of an issue, but glute injections can take a while. I wish I had taken a photo, but a few months back the plunger snapped during an injection, causing the syringe to turn, thus causing the needle to bend about 70 degrees or so. This is while the pin was in my muscle. But the pin didn't break.

But putting the vial in the microwave for a few seconds makes the oil thin enough.
