I never felt any energy from it what so ever.... But then again I never felt the shakes from Clenbuterol either........ And both of mine were pharmaceutical grade Clenbuterol/t3
But I know for a fact that they both helped cut the fat off me, but neither gave me an "energy rush"
You won't feel like you are taking ephedrine or clenbuterol or amphetamines, but depending on the dose you will feel like you maybe slept better at night. You will just feel like you have more energy overall but much different from stimulant energy if that makes sense.
