I’ve been taking it generally about an hour and a half before bed, but occasionally after my workouts also. I’ve been in a phase of training for potentially running a marathon (Never have I been a runner before), so strength training went on the back burner for around 3 months. I noticed my body was starting to eat away at muscle mass and was not happy, but within the past 3 weeks started supplementing with this product and have noticed incredible results. After being unhappy with what was happening to my body on a cardio heavy routine I reimplemented the bodybuilding regiment I had been doing before. I was afraid it would have to be one or the other, but I have been proven hard wrong (Keep in mind I’ve tried doing both before and could get through it but struggled mentally with the exhaustion I’d feel). I can now do my multiple body part training which takes just under two hours and immediately going into my daily cardio of running about 5 to 8 miles, but now with absolutely zero drop off. My sex drive was essentially nonexistent for the months I only ran, but now I can do both weights and cardio in the same session and everything seems to be back to normal with my sex drive if not significantly better! I have been able to regain the muscle I thought had dropped off me (glycogen depletion and insignificant utilization of my upper body I know), but on top of that my strength levels are higher than before I stopped weight training, my pump has become incredible, my hormones truly seem to be realigned and in peak condition, and my body as a whole seems to be functioning just much better. I think I would highly suggest this supplement to any man who may fear their hormones are off or are simply wanting to try and improve their body in many aspects. It’s great for cortisol levels as well, if you seem to be consistently stressed like myself, and really helps me feel great the next day as well, no matter how I feel I’ve slept the night before. Long story short, if you’re hesitant about trying this then don’t be and take the plunge. From what I’ve noticed myself I’d say it is more than worth it and I will consistently be repurchasing.

5.0 out of 5 stars Potent dose and clean make-up

I take this about an hour or two before I go to sleep every night and it's helped with my sleep issues. It keeps my mood more regulated and also helps with any fogginess. I've checked a few brands and I've tried a few different tinctures and so far this is my favorite blend. One of the better brands out there!

4.0 out of 5 stars Worked better in daytime than night for me.

When I started taking this, I was taking it before bedtime, hoping it would relax me. I found it had the opposite effect. After a week of terrible sleep (according to my sleep tracker I was getting barely any deep sleep), I switched to taking this first thing in the morning instead.Since I've made that switch, this does seem to have a positive effect on me. I find myself 'locked in' and able to focus on tasks for a lot longer. I used to not be a morning person at all, now I get so much done in the first few hours of the day.

5.0 out of 5 stars Very good value for the money.

Almost as good as alpha brain.

5.0 out of 5 stars Possibly Making Me Leaner

J.B. · April 3, 2025

Not sure if its this supplement but I am definitely getting leaner. I tried on a polo shirt yesterday that used to be tight and it fit pretty well. I also noticed that my stomach looks flatter. But I have been eating a salad every night and working out about 2 to 3X per week, mostly lifting weights. I am going to keep taking it and see what happens.

Good but I have tried others who made me feel better

5.0 out of 5 stars Great

C.O. · December 31, 2024

I don’t like having a lot of supplements but I will always keep this stuff on hand. I couldn’t tell if it was doing anything until I stopped taking it. The difference was immediately noticeable.

Having just finished my first 12 weeks of Ashwagangha (300 mg twice per day of a different brand) I was primed for wanting more. I've only taken this one for 2 nights -- before bed -- and I really like it. No issues and already sleeping better so, as far as I can see, Jacked Factory is my new brand from now on. Thanks.

Effective amazing product!

Would highly recommend!

Really works on me.

M.C. · March 3, 2024

I wanted to try it out to see for myself and I had really low hopes it would do anything. I thought it was like all other natural products just waste of money and on an expensive pee ,but boy what a surprise! It really works on me I felt I had better sleep in the first week I started taking it. After a couple weeks I started to notice an effect on stress aswell. I dont know if it's all in my head but it does work on me.I really hope Jacked Factory will have the product back in stock by the time I finish this bottle because I will certainly buy again.

Noticable stress reducer

J. · January 25, 2024

A started taking this in the morning, especially on days when I know I'm facing a busy day. Wether it's stressful meetings, or anxious clients, I appear to do better on the days when I take it. It's easy to swallow with food or a drink which I would recommend as it does have an almost earthy taste to it.

Never in stock

I like the product but it’s always out of stock

in accurate ingredient label on page

Most people will not have a problem with the ingredient they forgot to list, but I do. The product contains mono-crystalline cellulose. A small portion of people know they have a reaction to this, it is a pain when it is not listed, and not returnable.
