IMO it's one of two things:
Firstly, why the heck are you injecting 3.5mL into the quad? Injecting tren is painful for me; let alone w/ a highly concentrated test (obviously yours is 300mg/mL or >)
Second, why don't you just split up the injection protocol? Just because they are both long esters doesn't mean you HAVE to inject x2/wk. The most efficient way of keeping blood levels stable (yes, even w/ long esters) is to inject each day.
IMO, your solution is simple: switch to EOD injection schedule. Hit 1.75mL into each delt, and both quads.
Or just reduce the volume of injections even further and inject ED (this way you could cut B12 / more sterile oil into the injections to further avoid injection pain.)
^^ This seems mad over-board to me though (especially for someone doing 1g + of test & 800mg/wk tren...)
.... Use an ice-pack if you're sore post injection.
