Jacked Factory Essentials Muscle Builder - ATP Muscle Builder for Men with Peak ATP to Support Muscle Gain, Enhance Athletic Performance, & Increase Strength - 30 Capsules

I am noticing great, as described, results from JF Essential Muscle. My strength & definition shows the most improvement in the 2 weeks I've used this product.

Been using for a month have to say im impressed with this product its affordable and works really well i use 3 times a week and im able to increase my weights by 20 to 30 lbs about week and a half apart

All good but its not really that noticeable.... I couldn't figure out where the extra gym energy went. I m caffeine free but switched things up didnt notice until I started these again. This is the extra 5% at the gym

Placebo or not, I feel better when I take ATP after I workout, or on days I feel exhausted. I think it seems to work, I’ll keep buying!

Supplement is exactly as stated on bottle. Taking this supplement exercising helps build strong muscles. Love It!

I'm already on creatine, what more could I expect from this stuff? Well I did expect something. It doesn't seem to give me extra energy or better pumps or anything measurable or noticeable. Might be doing something, but another 20 bux a month for something that I can't notice the difference with? Nah, I'll save my money. No side effects, just nothing of any significance to report.

The Review questions are a little silly. There is no flavor. It is a capsule. The flavor is neutral unless you let it dissolve in your mouth and I wouldn't do that. "Ingredient quality"---who knows! (I am not a chemist). However, it appears to work for faster recovery from high intensity weightlifting workouts as well as Muscle Builder (which got too expensive). It is a sample size of the one so the standard of deviation would have to be high but in my own 12-week study with and without, I found that taking this supplement helped me lift heavier weights sooner than when I was not taking it. With the supplement, I was able to lift a heavy weight for 6 reps to failure, and then on the next workout for the same exercise (days later), I was able to increase the weight lifted for another 6 reps to failure. When I was not taking the supplement and even with plenty of rest days, periodically I would hit sticking points and be unable to increase the weight to be lifted. This happened several times over the 12-week period. Many times, I had to repeat the same weight to be lifted for several weeks before I could add weight. When taking the supplement with the same number of rest days, I was able to increase the weight to be lifted on every exercise day. (Since all the other variables were the same, I attribute the weightlifting success I had to the supplement). Currently, the price for a 30 day supply is reasonable. (I hope that as more people buy this, the price does not rocket up like the last brand I was taking. Hopefully, more sales do not translate into a higher price per bottle). Otherwise, I rate this product A++ or 5 Stars.

No measurable impact. No results. Placebo at best.
