Creatine Serum for Runners, Marathoners & Sprinters. Endurance Sport's Pre-Workout Boost: Energy, Speed, & Muscle Mass. Enhances Performance & Recovery. Strawberry. 5.1 Fl Oz

I’ve used this product for a few weeks now. Here’s my opinion...I was looking for something to give me a boost of energy, since I feel super tired and sluggish all day, especially after my high intensity workouts. I do plyometrics, cardio and weight lifting usually. Some of my workouts last between 30 and 80 minutes per day… but lately I couldn’t do it daily cause of the lack of energy. I also have to sleep longer after my workout days, which I have an issue with cause it interferes with my daily AM routine. I gotta be up at 7 AM. Sadly it seems as though I'm running out of stamina, and my super healthy diet and lifestyle is not enough.After looking through lots of workout products, I thought I would give this one a try.The product arrived sealed and well packaged and on time. Expect the taste to be tarty and bitter as if you’re drinking a concentrated dose of vitamin B12 or Thiamine or Niacin. But it’s also not horrible either. Doesn’t bother me at all.The first time I took this was in the evening per dosage directed. I didn’t feel any different. I thought I was going to feel the inner superwoman unleash after a few minutes, but nothing happened. So I just thought maybe this thing was just a fluke.To my surprise, when I worked out that evening, I was able to work out for longer and it wasn’t till after my workout that my brain fog went away. Just a wonderful boost of mental clarity. Lethargy and sluggishness gone. So much that I couldn’t fall asleep so I just read a technical boring book and was able to get through it.I woke up at my usual 7 AM. Didn’t need to hit the snooze button 10 x this time. No lethargy! It was awesome!I did the same on day 2, experienced the same thing.As much as I want to read at night, I also love my sleep, so now I take this at midday for my evening workout and fall asleep at a normal time.I am happy to say that I don’t feel jittery, nor have I experienced a crash or any negative side effects. If anything, I feel very normal without that sluggishness and it feels very natural, which is exactly what I wanted.I can also endure through my evening intense workouts without having complete exhaustion later. Maybe other individuals are different but for me, taking this a few hours earlier gives my energy a head start before I start the workout.I am a huge fan. I’ll be ordering more.

The taste was terrible but I was able to complete a 2 mile run without stopping for a break and I hate running lol

Of course, everyone's body is different so be mindful what works for one might not work for you. I ordered this to start back running with the runners peak serum and the first week I didn't think it did anything so I continued taking it the second week I noticed I was running longer without stopping and my breathing was better I did not feel tired just my lazy mind sometimes gets the best of me. A change of mind and attitude towards running increases the effects, remember that. I have to trick my mind into believing I love running and eventually my body continues on its own with the help of this product. Mind over matter!

For the "single star reviews," it's a serum, sure it's going to be a bit tart. But to say you couldn't get it down, that's hysterical.I thought the taste was great considering the creatine products I've tried in the past. Sure beats swallowing a glass of sand-water (creatine monohydrate). Can definitely feel the difference in my overall energy. Been using before (2.5 mL) and after (2.5mL) workouts and will certainly be ordering more.Oh, and as for the expiration date reviews, see attached..

Expensive but works.
