Hope this hasn't been post before is so I am sorry. I think this can help some:

Dealing with high BA content
I thought this was an interesting read for anyone suffering from painful injections related to BA content.

Reducing Pain From Injections
Many people complain of pain when they shoot IP's (International Pharmaceuticals) testosterone products, Sustanon made by varying companies and Denkall's Test-400. Below are techniques that will take care of any painful oil injectables that you may have:
Buy some Sesame, Soybean, Safflower (whatever kind of oil you like) oil from the store. Take one of your old 10ml bottles (we all keep'em around) and sterilize it using 91% isopropyl alcohol or 99% if you can find it... Meijer carries 99%. Pull the aluminum seal off the bottle and throw it away and pull the stopper out (keep it). Sterilize a small bowl using the alcohol and then put enough alcohol in the bowl so that you can immerse the bottle and stopper in it... leave it sit for at least 15 minutes. Take out the bottle and rubber stopper and let them air dry. Once the bottle is dry, fill it with sesame oil... you can use a filtered syringe if you want but I've never found that necessary, especially if you use a syringe to just take the oil off the top of the bottle. Now place the bottle in the good ol' microwave and nuke it for 2 minutes on high. Leave it sit until it cools and then place the rubber stopper back in the bottle.
Next time you go to inject, for each cc of gear you withdraw in to the syringe, withdraw 1/2cc of regular oil. That's a good starting point and should do the trick for ya... if not, increase 1/4cc until you're comfortable. If you have a severe reaction to BA, you may need to go cc for cc.
There's also another trick concerning BA. If you have some bacteriostatic water or sterile water sittin' around try this.
If you're shooting 2cc's of an oil injectable, withdraw your 2cc of whatever oil inject you're using and then withdraw 1cc of the water. Put that in the fridge and let it sit overnight. Next day, tilt the needle up and shoot out the water. This removes much BA because BA is more attracted to water than it is oil! Might wanna try that also.
Both techniques work well
