Tweetb12 can help cut prop pain, but thats only if the prop has too much ba in it. it helps because ba is sol at 4% in water, so 1ml of b12 mixed in with the oil depot will cause some of the ba to migrate from the depot into the b12 or water. water disperses very quickly in our bodies, so the ba wont hang around and damage muscle tissues causing pain.
if the prop is painfull because its crashing(not enough solvent or ba), b12 will make it much worse.
imo sterile oil is the best, it always works, whether pain is caused from crashing, or too much solvent...it will work best
steroids with an ester(propionate is an ester) are more soluable in oil/fat/lipids, and much less in water. the longer the ester, the more oil/fat/lipid sol it becomes. this is why longer esteres release slower, as they like to stay in the oil or fat longer as they as the longer the ester is, the more oil soluable they become, and also the longer the ester, the LESS water sol they become. our blood is water based, so if somthing is not very sol in water, (or blood) it will be difficult for the enzymes in the blood to cleave the ester off. and we all know, until the ester is cleaved off, the steroid is not biologically active and cant make us grow. so since esters like oil, and hate water, give them what they like and they will stay dissolved in it, and will not crash out causing pain.
thats why cutting it with oil works best with anything dissolved in oil. but if the gear is painfull due to too much ba(this is usually not the case) then its great to be able to use b12, cause if you use b12 anyway, thats 1 less injection.
