Overall rating: 4.8 / 5 from 139 reviews.

I love the estrogen-reduction effects of this. I have blood work to prove that it works. A couple of years ago when I first tried this and I was on TRT, my estrogen bottomed out because I didn't realize how good it worked. I mixed it with my prescription.

Core Hard

Seemed to do what it suggests. I have no complaints.

Core Hard

I’ve competed 3 times this year, and Core Hard has allowed me to retain a competitive physique year round. Getting competitive levels of bodybuilding conditioning has been a breeze with this product!

Core Hard

I take 3 capsules before bed.... my recovery and rest quality have increased exponentially! Not to mention it's helped me drop ten pounds so far. Great product from CORE!👍 Great service from TIGER FITNESS!👍

Core Hard

Amazing product, phenomenal stress relief, great for body recomp if you’re on top of your diet.

Core Hard

I love Core Hard. I’ve been using during competition prep for 7 years and I love what it does.

Core Hard

I usually stack this with Drop Factor and Yohimbine HCL. It's a nice supplement stack to use before getting ready to go on vacation or if you just want to see more definition. Keep the diet clean of course.

Core Hard

Can’t go without it

Core Hard

I been using this for 3 weeks and already can see the change in my lower back.. which is my trouble spot. Money well spent.. I will be reordering again.

Core Hard

I love this product. It really excels in keeping my energy levels stable and cutting those stubborn areas while dieting.

Core Hard

I love Core Hard. Stress tends to jack up my digestive system, but Core Hard keeps everything in check. I've also found it very helpful when I'm doing a lot of running. Running increases cortisol, so I like to have a product to help control it.

Core Hard

Just started this product and so far so good! I feel calmer in a way and also no side effects. It also really controls stress eating. If cycle works well I’ll definitely buy again!

Core Hard

This one is a good one for me mainly because it doesn’t mess with my sleep. Most supplements such as this one can leave you with too much energy when it’s really bed time but this allows me to get rest and recover so I can hit it hard the next day. Along with helping me drop 2% in body fat and keeping my muscle full and solid, it’s a great product. Most likely going to purchase again.

Core Hard

This product really works. Been taking it for 3 weeks and have shredded off that extra weight before summer

Core Hard

Been using this for about two weeks so far with drop factor and yohimbine and works great, muscles stay full and hardened

Good estrogen control without any added stimulants.

I love core hard in and out of prep! Helps with hormones and body composition for sure.

Core Hard

Great Product.

Core Hard

This is a staple in my prep stack with drop factor and mts yohimbine

Core Hard

One of the best stacks around :raised_hands:

Core Hard

Feel a difference.

Core Hard

While this still not completely counteract the effects of lack of sleep and poor nutrition, it does help with keeping the catabolic properties of stress at bay along with offering some hardening affects by attacking estrogen. It is definitely worth a look if these are desired effects in your regiment.

Core Hard

Took this the last few weeks of my contest prep, and I noticed a substantial difference. I definitely recommend this to any competitor, or anyone trying to tighten up!

Core Hard

It’s an excellent product overall. I do feel my muscles get tighter after about a week of using it. I would recommend it for cutting season.

Core Hard

Didn't notice any difference other than a raging case if acid reflux.

Core Hard

Core hard is one of the best body composition products I’ve ever taken. Keeps cortisol low!

Core Hard

Took this with Drop Factor and Core Alpha. Dropped body fat by 2% and diet wasn’t even strict. Definitely reordering.

Core Hard

Thing is.. It works.

Core Hard

I am a very anxious person, and my cortisol levels are normally through the roof. This has changed that, and I have found it a LOT easier to control my anxiety. Reducing my cortisol levels has also allowed me to have a better workout, and sleep better at night. I am not sure if the recomping claims are real, but I highly recommend this supplement for those interested in reducing cortisol levels.

Core Hard

This has ashwagandha in it that uses milk in the extraction process. Other than that it works.

Core Hard

After just a week I could tell a difference in my body composition. I have been hitting it hard and haven’t felt better than when I am on HARD. AMAZING product!

Core Hard

Does what it claims to do.
