  • 9.9/10  Excellent. Saved Life; Literally.

    By R.C on Monday, April 30, 2018 02:26 PM

    Effectiveness: 10/10

    (+) Convenient,Easy To Take,Quickens Recovery Time,Works quickly - 4 days.

    How did you use it?:Every Morning

    "Was taking medication 2 years, taken off because genetic tests showed it was harmful to me. No withdrawal (weaned carefully) but month later, suicidal depression! WoW! Didn't know what to do for 3 weeks. Brain injury caused by medication desperately made me want to kill myself. I've never felt anything like it.
    Then found several reputable studies showing 300mg/day 5-HTP as effective as Prozac but no side effects. So I copied. In 4 days depression completely GONE. Have tried other brand but enteric coating prevented intestinal absorption; pill passed right through, untouched. No enteric coating on this makes it easy to absorb. And NOW brand very open about testing: they have their own lab. Ask and you get any answer you want without hassle.

    I have Multiple Chemical Sensitivity Syndrome and get bad + rare side effects to everything pharmaceutical. Tons of food allergies. But no side effects or allergens to this! So grateful!"

  • 8.9/10  Works Great, but be careful

    By Adam Greene on Thursday, July 13, 2017 08:27 AM

    Effectiveness: 9/10

    (+) Boosts Energy,Better sense of wellbeing
    (-)  Gave Me An Upset Stomach,Serotonin Shock

    How did you use it?:Every Morning

    "Make sure you take it on a full stomach. I don't recommend taking it without a medical practitioner prescribing it as it can cause serotonin shock (which, trust me, is not fun and can be dangerous). I took 1 tablet (bottle says take 2-3 / day) and first day found my mood was much better, second day gave me serotonin shock (temperature spike, nausea, and I felt horrible for the day, opposite of desired effect). I recommend getting the 50mg bottle instead and start with one / day and increase as necessary."
