Current Blast:
(Test E: 720)(Deca: 600)(Tren E: 400)(Mk 677: 12.5mg before bed)(6mg Aromasin E3.5D)(10mg Nolva EOD)(5mg Cialis ED) All homebrew gear and raws.

Weather is good now so went for run outside.
I was like NOPE at 3/4 mile.
Not only has my cardio took a hit... (expected)
But the extreme pumps from MK 677 had my shins feeling like they were going to burst through the skin, pretty much entire lower body beyond pumped that it inhibited me from running, along with back pumps. The pump is the main reason I had to switch to jog 90 sec, walk 30 sec, instead of just running the full 2 miles nonstop.

I can of course run 2 miles on Treadmill with less pump issues, because the belt moves instead of me propelling myself forward(Captain Obvious).
We know that treadmill is nothing like actually running, but winter weather wouldn't allow me to run outside. Nearest indoor track is to far away.

I have a physical fitness test which includes a 2 mile run in 1 month. I am near end of blast so dropping Tren E completely, and taking MK 677 12.5mg EOD for while.(I am hyper sensitive to mk 677).
Test E to be 720mg/wk and Deca 600mg/wk.
Increase AI to 12.5mg E3.5D (injection day) to cut some water weight and such.
Drop Nolva.
Jog EOD.

I did somewhat fall off on cardio because of recent vacation and stuff. But again... the pumps were the main issue. MK 677 is by far the best compound I have taken for sheer size and pumps that harbor an environment for exceptional growth during bulk.
