It will absorb in about 4 days! Next time, use 1 to 1 1/2 inch 25 gauge needles, and inject directly into the glute upper portion of the glute! Once you sink the needle, pull back on the plunger (aspirate) to check for blood being drawn into the needle . If there is blood reinject your needle! Once there is no blood , slowly depress the plunger to evenly dispense the gear! Good luck
