i read somewhere that if you inject in the delts the half life is gonna be longer than in the glutes, doesn't make sense right
might not make sense to you but its true. not half life, but absorption rate. smaller, denser muscles slow absorption relative to larger more "loose" muscle tissues. gluts are faster than delts. i forget where i saw the pharmokinetics on this, but it was a leghit pubmed study. wont make a difference to your results from a cycle though.
