Great stuff, great company, great price. So let's take a deep dive into this because I love DLPA it's amazing.I got clean off heroin almost a year and a half ago. I run at least 1.5 miles 4-5 times a week, sometimes I'll end up on a lot longer run. It really helps me keep my head in the game. I'm also on methadone and it's absolutely a life saver as well.I bought DLPA about six months after I got clean, I was lifting weights maybe once every 7 to 10 days but I drank protein shakes every day twice a day. I didn't realize that it already had a LOT of l-phenylalanine in it. But at this time I felt good and didn't notice any benefit, I'm guessing cause I already was getting all the phenylalanine I needed more or less. So fast forward to about 3 months ago, I was struggling with anxiety and energy/motivation and NOT drinking protein shakes as I quit lifting any weights because I injured my hands at work. I was getting ready to go to the methadone clinic in the morning. Usually I feel a very mild state of wihdrawal in the morning before I dose. It had been a while since I took some DLPA, and up until this point the only benefit I noticed is it made caffeine more effective. I took 1000mg of DLPA and within 45 mintues I felt postively adjusted in most of the ways I needed. The minor state of withdrawal was almost completely eliminated. After this I continued to take it and am so grateful I stumbled across this supplement. I was at a point where I felt like I had hit a wall in my recovery from heroin. I would remember how much better I felt when I first got sober and had almost accepted it was just a honeymoon phase. Not at all the case. Phenylalanine helps your brain refill your dopamine and norepinephrine, which are extremely important neurotransmitters. So apparently, I was just not getting enough in my diet. But it makes a huge difference. As a former addict using supplements, my brain is always looking for a strong noticeable effect. But I was too focused on that to pick out the benefits in the past. So when I was in this low dopamine/norepinephrine state I actually noticed it. Some of it gets metabolized into phenylethlyamine (PEA) which is a strong supplement that resembles amphetamine/MDMA in effect depending on dosage.In closing, I'm so glad I found this because I was at a shitty place mentally and it was starting to threaten my sobriety. Now I take approximately 2000mg or 2 grams a day sometimes more. I start to notice my mood drop and anxiety increase if I stop taking it. Ususally within 48-72 hours I start to feel my underlying anxiety disorder take the front seat again. That all is to say, theres no withdrawal or anything, I just notice the difference so much when I run out. I've tried so many supplements that did ABSOLUTELY NOTHING, probably 95% of them, but this one actually works. If you're feeling down, no motivation and anxious about stuff more than you normally should, give this a try.TL;DRDLPA Helps significantly with motivation, mood, anxiety and focus. Absolute game changer for me. Pairs well with caffeine. It pairs AMAZINGLY with exercise too. It's cheap as hell and helps with my mental health without feeling drugged in any way whatsoever. You just feel naturally good.This has been a lifesaver for me! It has helped so much with pain from a herniated disc caused by an auto accident. I stopped taking it at one point, and the pain increased a lot. I love having a natural solution to help with pain. I make 00 capsules and take 2 of them 2x a day.I waited to review this product. I have been using it daily for several months now. Overall, I would recommend it. The first week of use was difficult, I had a blinding headache for days but I reduced the dose and powered through it. I began to notice an improvement of my chronic pain and the low energy low mood that accompanies it within that first week, minus the headache. After the first week I felt good. Headache disappeared and the pain was minimized to a tolerable level. After the first month, I noticed it was less effective so I increased the dose slightly. It helped, but effectiveness diminished again. So I took a week hiatus and restarted at the last dose I was taking. That worked. I noticed an improvement, but sadly, also the headache for the first few days. So my regimen now is 3 weeks on, 1 week off, start low and slowly increase the dose for the first week. I mix the powder in my water flask with vitamin C and sip throughout the day. In the beginning, start with small doses, use a scale with your measuring utensils so you can get an accurate idea of how many mg are in your 1/8 tsp etc..Only been taking 3 days. 1 flat tsp daily. So far noticed energy I guess. Decided to play Just Dance with some younger friends yesterday. While they were tired and winded I wasn't not one bit. Strange cause I'm usually tired after 1 song, but we did two and I felt good as heck. I'm almost 40 by the way and out of shape and smoke. So, if its helping that's great.Won't say it's done anything for mood or sleep at the moment. Hopefully it does cause It's why I decided to give it a try. I have anxiety and mild depression.UPDATE: Well idk how long it’s been since my last review but I def see a change in mood. I noticed because all my negative emotion happens at work. Lately, I’ve been thinking clearer, more positive and just plain happy. Also my memory of things I enjoyed are coming back.I may add, and idk if it’s because of DLP but orgasms seem to be more intense in feeling. Very intense.I do have depression and anxiety, but since taking this, it has gotten better. I mean I still have it, but I’m actually starting to enjoy things again little by little.FINAL UPDATE: Doesn’t help with mood any more. Took a 2 week break and starting taking again and still hasn’t helped any more. Good for a temporary mood boost I suppose.
