Or, you just felt good because you had a bunch of trest in your system, then when you came off you no longer had the trest and whatever hormone was out of whack started fucking you up, because the OTC things you used did NOT control it.
Happens all the time; guys feel great on cycle because they’ve got a ton of androgens floating about but they don’t manage their E, so when they come off their test is all of a sudden in the basement but the E is still sky high.
