Doesn't the injection pain come mostly from the body absorbing the oil that the gear is suspended in and thus leaving behind crystals (wording???) ? My first batch of Sust was highly dosed at around 20% BA and it wasn't too bad at all. I always thought it was the higher concentrations of the substance per ml/mg that is what caused the pain due to the body absorbing all the oil before all the 'said' steriod compound.
