Yes, if you're using it for anabolic effects, you could get more stable levels with two injections a day. But since trestolone is pretty strong on the adrenergic side, it’s better to take it all at once in the morning so it doesn’t interfere with your sleep.
Honestly, I don’t get why someone would use it just for the 'positive mental effects'—after 8-10 hours, you’ll feel flat until the next dose. And blood pressure isn’t controlled by injecting every other day; it’s improved because EOD injections mean you're injecting half as compared to daily dosing, which helps keep BP more stable.
