Ok guys, got a quick question for ya. I've run many PH cycles, but never real gear, so I'm curious about something. I got some test e from OP, spiked 500 ml Saturday night, got test flu this morning (Monday morning), but it went away after 6 hours or so. I'm curious; how do I know it's working? This morning could have been viral (wife was feeling off too), but I'd really like to 1) verify it's working, and 2) see if I should up dosage. Any suggestions? I would go by energy level, but I normally feel like a million bucks, so hard to tell.
