King & Core-21 Customer Reviews

Great products so far.
Great products and they are expensive but probably worth the extra cost.

Just the beginning
Just began this product, so far so good. The Core 21 had me sleeping like a baby! As for the Royal XXI, I did not feel anything or I’m not sure if I’m suppose to? But with all the other products I have from 1stPhorm, I do not doubt it will be highly beneficial!

Royal flush
I feel like the Royal is scouring the excess fat in my gut. I think I see the junk food from last summer exiting my body. No jitters, bumping up to 2 caps per day as my body is adjusting

Finally shedding
Maybe my nutrition was off but I started storing fat instead of burning. This combo plus my transphormation guidance got me moving in the right direction again and I'm down a few pounds. Total package from the 1st Phorm and this product.

This is one of the best combinations of supplements that I have ever taken. Core-21 knocks me out within the hour of taking it and the Royal really gets my mind and body focused on attacking the day. I love these two products. Continue doing what you are doing with these two products

I have always been a fan of royal xxi. Easy to lose weight, and on the cheat days it helps you maintain where you’re at. Had some of the best sleep in years with core -21. Some of the best rest I’ve ever had.

Instant results. Very surprised!
I've been using the King and Core-21 stack for two weeks now and I love it! The reason I purchased this stack was to fight the cravings I would get through out the day for sweets. Honey buns, and soda are my biggest enemies when it comes to cravings. It doesn't help that I work in an office with 4 very well stocked vending machines. From the very first day I started the tolerance assessment phase of King I could instantly tell my cravings stopped. Sure I was hungry, but I didn't crave sweets. I didn't fiend for that release of endorphins that came from taking a refreshing gulp of soda. Now that I'm on week two and I've moved up to the maximum recommended dosage of 2 King in the morning, and 2 five hours later, the cravings I would get are not even the slightest issue. As far as weight loss, I cannot fully give credit to King as my sugar intake has basically ceased, it has undoubtedly accounted for a drop in my belly fat. Its also helped me maintain intermittent fasting for the majority of the day so my calorie intake is down as well. Maybe the credit does all go to King since it suppresses appetite? My energy levels are definitely up throughout the day despite no soda (caffeine). I haven't needed an energy drink to get me through the last hours of the day at work. I'm very grateful for that. I haven't noticed an increase in body temperature. Digestion is normal. Slight jitters the first week. Second week with increased dosage the jitters are less than the first week. No ill side effects to report.

Core-21 seems to do exactly what it says. I take 3 capsules roughly an hour before I plan on jumping into bed, and by around 30-45 minutes after taking them there is a clear defined moment where I go from normally awake, to tired and felling like I could fall asleep within minutes of hitting the pillow. And that is exactly what happens when I do lay down. I've always been an intermittent sleeper, and I don't stay asleep, but I feel like I wake up less through out the night. When my alarm goes off at 6:45am I can easily get up and get my day going. I feel quite rested. I love the fact that they help me fall asleep fast.

Total weight loss over the past 2 weeks has been a solid 5lbs. Obviously I fluctuate, but towards the low end its definitely 5lbs gone. I have not been weight training during the time I am taking this stack due to a back injury, but I have no doubts the results will amplify with resistance training. Super happy with this stack and will continue to help me reach my body fat goal.

Appetite suppressant
The biggest thing I noticed from taking Royal XXI was the lack of hunger. I love to eat, but food just wasn’t at the top of my wish list while taking this product. No noticeable effects outside of this. The Core 21 product provided no noticeable benefits.

Legit products
The core 21 is fantastic for giving me that extra edge for recovery while I sleep. It’s one of those products that as it gets closer to the bottom of the bottle, you get upset but then realize you can order more lol. The Royal is awesome. Or of the best fat burners and endurance pills out there. Will purchase again.

Great product
The Royal king is great for curving appetite but does not cause any jittering feeling. The Core-21 is amazing. I take it about 30 mins before I want to fall asleep. It lets me sleep all through the night and I don’t struggle to fall asleep when using it. I reccomend both of these for anyone who wants a little extra help to shed a few pounds.

Trying this for the first time.
Well I just received this product, seeing as how I had the order go to my wife first before sending it to me overseas. Starting the first week to see where my tolerance is , I’m only taking 1 pill as directed. So far so good, going to increase by one this next week.
I have read other reviews along with what my wife has been saying, I have high hope for this product in reaching the goals I want my body composition.

Honest review
Absolutely nothing. I thought Royal XXI was gonna kill me. It was too much for my system. I was trying to assess my tolerance and i learned very quickly my tolerance was 0 capsules. Please read the labels thoroughly BEFORE you buy it and consume it. I did both and still wasn’t prepared.
Core-21 was ok. I wouldnt purchase it again though.

I really like the Core-21 product; however, have't really used the Royal XXI fat burner much. Tried it once and it made me jittery. Might have taken too much to start so will try again with a smaller dose.

Review by Benjamin / (Posted on 2/20/2018) | Verified Review

Some of it works for me and some not so much
The C21 made me hungrier and more wired. It actually contributed to me getting significantly less sleep and eating more. I don’t know if others experience it or if it’s my body chemistry but I tried it for 8-9 days with progressively worse results. Won’t use again. The Royal 21 worked great for the first few days but only see a tiny difference since. Maybe it’s because I’m so tired from 7 days without sleep from the C21. But it does provide some help and I’ll continue using 5 days on 2 off for the foreseeable future. If the effects continue to wane I won’t reorder though. Kind of disappointed.
