I've taken both at that level and I VASTLY prefer primo over EQ (as a matter of fact at ANY dosage level).
There is no comparison. Primo is side effect free for the most part for me. Just good clean gains, recovery times decrease, bodyfat is easier to keep in check while gaining mass. My BP actually drops a little on primo. On EQ my HCT goes up to dangerous levels, I bloat unless I add in AIs (which I hate taking), BP gets dangerous high, I get disturbances in my sleep (sleeplessness and nightmares)....its garbage.
If Primo didn't exist I'd be on 70mg of testosterone and IGF/GH only, but thankfully it exists and I can run 200-700mg/week as I see fit
