Ephedrine is b.s. ....increased heart rate & blood pressure, no thanks (unless you remove that pesky little Hydroxyl group off the beta position lol)
Phenylpiracetam is an amazing general stimulant. You can buy online at multiple places
L-Carnitine and Acetyl-L-Carnitine are also great
Korean red ginseng is great
Rhodiola Rosea is great
a lot of those ephedrine and related compounds are cardiovascular taxing and carry risks, heart attack, stoke, circulatory collapse (in large amounts, doing strenuous physical activity, with pre existing cardiovascular issues), in small amounts they could be helpful but there are safer and better options.
Phenylpiracetam was chosen by a lab rat over Methylphenidate (Ritalin) and Amphetamine in place of the lab rats special treats it loved. (An online study review I read, maybe Wikipedia lol ?)
It was also banned in Olympics as a doping agent....a performance enhancing agent
I personally use Vyvanse (d-amphetamine) and Ritalin, but I also have Phenylpiracetam and it’s a great general stimulant, very safe and little to no increased HR & BP. It gives a laser like focus, promotes vigilance, and gives energy. Increases dopamine amongst other mechanisms of actions....look it up.
Nootropics Depo has 100mg capsules that I buy online, shipped to Canada.
Great company, great product, fast shipping.
