holy shit i think, looking at that pic
i am injecting in the "fascia" region 
If you inject enanthate or cyp you only need a once a week injection, I just alternate left and right hip...Have been forever. Haven't used a dif spot than that "glute medius" hip area for a very long time.
Each hip gets it every 2 weeks, plenty of time to clear out and heal.
If you have a big lump or something come the 2 week mark your gear is fucked and/or poisonous, focus on getting good gear. I get a small painless lump that starts dissipating around 3 days post inj. and is completely gone after 5-6 days, leaving another entire week to completely break up and heal leaving no real "scar tissue" scar tissue in this context is from continuously hammering multiple cc's into still lumpy sites...
2 sites is fine for guys doing 1-3 cc's per week...
