I used to use PWs that were extremely intense. This one is up there but not like the ones I used to take. Excellent taste, mixes well, it was sour but it made the drink bearable. The scoop is big just like other reviewers have stated. It could just be me, but I took this about 30min before my workout, had an 1.5hr full circuit workout, but i feel like the product actually kicked in after I got home lol. It was a delayed release of energy. It very well could be me and my physiology, but that was my own experience. Overall, I like this PW and would order again!

Really great pre-workout compared to other pre-workouts I've tested. This pre-workout really gives you the energy needed to sustain pro-longed intense workouts. Great muscle pumps and recovery. Doesn't make you feel exhausted easily! Additionally, unlike other pre-workouts, I don't feel tingly sensation when the effect kicks in! The price is really worth it as it really gives you the boost in performance that you needed the most! Though the taste may vary for some individuals as it has some bitterness and not really that sweet as it doesn't have any sweeteners. But overall, this pre-workout really exceeded my expectations! Highly recommended and definitely will be ordering again!

I find this Bulk Black pre workout to be better than average. It does work well at giving a bit of extra energy to push through your workout but it does tend to take a little extra time to kick in. Depending on dosage, I notice a bit of skin flush, so I tend to take just enough to feel it but not so much that it is uncomfortable - take too much and it can be. I actually like the taste, but like most things in life, taste is definitely subjective. If worried, I suggest purchasing the cheapest size, and then sticking with a flavor you like. It seems expensive at first, but realizing it works better than the same amount of the regular TL pre workout, and I use less of the Bulk Black, so in my opinion it's worth it. I also only use it when I need it. It does also make a good substitute for morning coffee or pick me up when you need it.

Been lifting for over 8 years now. Tried countless pre workouts and I absolutely love this one. Taste is horrendous and makes me gag every time, but totally worth it. Gives me lots of energy and insane endurance, without making me jittery. Laser focus. Love this product! Just wish it didn’t taste so bad.
