Whats BA ?
The brand is Chemblend. And have no idea what the ba is.
Make sure you are injecting the needle into the muscle very slowly, and injecting the actual test very slowly. Afterwards massage the injection site to help the oil disperse throughout the muscle. It will take much longer but that will help with the pain somewhat.
Beat me to the punch.Also maybe try warming your gear when its loaded into syringe....i put it under a small lamp...hop in shower and when im out the oil is warm...muscles are relaxed..etc. some guys wrap the syringe w a warm washcloth too. If that and a 25g doesnt help...get new gear bro. Good luck.
