Perfect Amino Acid supplement for happy arteries and lower blood pressure!I’ve used the powder for several years. Worked great, tasted bad. These capsules eliminate the taste issue but leave me a question: the amount of powder in the capsule is a fraction of the dose the instructions said to use of the powder. Both seem to work. And the contents of the capsules seems denser. I guess that’s how it contains the same dose.Can’t explain for certain but as long as the capsules work for me, I’m satisfied.Good price, quick delivery. Appreciate the quantity.This is the same milligrams and dosage as what the doctor writes a prescription for. L-Arginine, 500mg comes in a bottle of 300 servings, not the 90 days the old fashion way. Do the math.only a week into use, can't yet know if it's workingGot the results I was looking for. Good buy.Went into the VA for a check-up, they wanted to admit me to the ER for my blood pressure. After much research and many months of using this in conjunction with other supplements, my bp is back to normal without any of the synthetic chemicals the doctors were so eager to put me on.I take it for a pump to help in the gym. I take two doses for best effect on an empty stomach 30 minutes before the first lift.
