Site injections work because the oil depot and inflammation cause a stretching of the fascia.......the sheath that encloses the muscle.....allowing room for new muscle fiber. There is no scientific evidence that steroids cause localized growth. Therefore, the higher the volume injected, the better. Forget about suspension.......low volume, killer pain. Plain old cyp or eth or eq is fine......or even - OMG - synthol - for that purose only.
Personally I had nice results with old fashioned ganabol......lots of oil, lots of stretching......permanent results.
