Im doing same exact cycle as you but 600 mg of eq and 600 mg of t200.
I inject Mon, Wed and Fri and I rotate each day with different injection site and this is how i do mine, mon I inject right butt cheek, Wed left butt cheek and fri left delt. Ive never had any problems with delt in fact its very painless and butt hurts more than delts if I compared both after injection. Hope this helped
