I purchased this product in store and I love it! There have been some ups and downs, and I broke routine for two days because I was sick and I was listening to my body tell me to stop so I can recover properly. Now, you must consider these pills a catalyst for helping to lose water weight and boosting your metabolism. This is not an answer to all of your needs, only an asset to changing your lifestyle! Your body goes trough some crazy changes when you start a diet and workout routine so this is meant to help create discipline. As you get used to taking the pills throughout the day you will also become aware of your eating and scheduling. This plan creates a necessity for scheduling your meals and workouts. I find my peak three hours into taking my morning pills and find that I no longer feel the need to take naps and my mental focus is constant until I take the sleep cycle. One month is fantastic, but if you can afford to save for a second month supply, I would recommend doing so in succession of the first box you buy. This helps your body to keep metabolizing fast and, again, help you build a healthy routine in your day.

Here are the negatives:
The first couple of days my stomach was hurting from time to time, but I wasn’t hungry. I had to try and force food into my body, but eating is necessary for your body to metabolize.
I had constant nausea for the first two days, then it began to regress into feeling normal again.
My anxiety was OUT THE ROOF! The energy you get from these pills is no joke, and I’m a barista who is an avid coffee drinker... I couldn’t drink coffee because it would make me jittery. I found drinking water, constantly, would combat this issue.
I wasn’t able to focus properly until about 3-4 days into the plan when my body adjusted to the supplements.

Feel so much energy
Weight loss was phenomenal! I lost like 12 pounds!
Helped discipline my lifestyle (I am bad at sticking to plans)
Working out was a breeze so I was able to hit new PR’s in cardio AND the weight room!

Overall: I would totally recommend this product. I am a 21 year old male at 180 pounds and 5’7” (Used to weigh 200 pounds!)

Great package, great idea, didn't work for me
The package was beautiful, the box was a marketing delight, I followed the instructions exactly as written. I bought the product to try and kick start my metabolism after several months of travel and poor eating. I am up from 206 to 226 and I wanted to short cut the drop. Unfortunately all it did was make me angry and give me a headache. I also learned that taking the night time CLA blend caused me to only sleep lightly so I wasn't fully rested in the morning. The thermogenesis worked in the sense that I sweated profusely but after 5 days I never really adjusted and returned it for a refund. I did not see any impact on weight, I was actually weaker at my mid day work outs. I did have more energy in he afternoon but I didn't sleep well at night. Overall a fail for me. Hopefully it works for others.

Really like this product
Been through one month of this product and I like it. I really feel like the sleep cycle pill helps me to sleep while having the CLA as well. I like this product and have seen weight loss and fat loss benefits. All of the Performix products that I have tried so far have been great

Test Run
I swear by Performix products... Ive been using SST & Stimfree for a little while. I would use the SST in the morning (gotta take SST on a light stomach or you will feel nauseous) and I did the Stimfree before bed... but now that they made LSC I can now get a constant burn basically all day and night.... SST in the morning Stimfree at lunch and LSC when I go to bed.... I'm really interested in seeing how LSC works...

Starting to use
I started to use few days ago and I'm felling bad/sick. It's really difficult to has a normal life, work and study using performix. I'm really considering to stop to use. I will try more 02 or 03 days.
And It's so expensive.

I desperately need sleep and love other Performix time-release products. I wanted to try their sleep formulation BUT had to buy two other products with it. I will not use others because they are loaded with caffeine, which I avoid. I wish the sleep aid was sold seperatly.

when do you take them ?
A shopper on Mar 21, 2017
BEST ANSWER: Follow the instructions on the box. You might want to start with one SST to see how you react before increasing to two.
If I am taking SST in the morning and afternoon, what does the Stim free add? Does it take the place of the afternoon dose or do you take them together?
