Very pleased, with more energy!
I tried these because I was having trouble getting motivated. I felt tired and lethargic and basically just couldn’t be bothered to do anything. It was a struggle just to get ready for work, and even get errands done. I had numerous blood tests done, and apparently there’s nothing wrong with me lolSo I turned to energy supplements and found these. I have been taking them for about 3 months and I am very happy with the results. I take two in the morning before breakfast, and I get through my day without wishing I could crawl back into bed! I tried taking an extra two later in the day, but they did keep me awake all night. If I was working out, I would try taking the 4 pills beforehand, but for now, 2 is fine. Since I started taking these, I am more motivated to get stuff done, and they clear my head which makes me more productive. I was expecting more of a physical energy…I wasn’t expecting them to help me think more clearly. But, that was exactly what I needed.Sometimes if I am particularly excited about something, I will get a little hyperactive, and I wonder if people think I’m on something lol but I’m aware of it and just calm down a little. These pills have truly helped me feel better, be more productive, think clearer and feel more positive, therefore I am happier. I would recommend these if you are feeling lazy and want a boost to get through the day. I will definately continue to use these : )

It’s a good value, I liked it.
A somewhat middle of the road Nitrix oxide. Good to get it and not be overwhelmed.

A great supplement to have on hand when in a rush on workout days.
I like that this supplement is built around citrulline for nitric oxide support, which is great for energy and endurance. It feels like a solid option for pre-workout, and the capsules make it easy to take without having to mix a drink. For this convenience, this is great to have on hand to reach the same functionality as some other powders. It does not cause jitteriness, and there is no taste.It seems like a quality formula for boosting performance and blood flow, and I appreciate that it comes in a big bottle with plenty of servings. For what it offers, I think this is a really good value.

Excellent product
As a celiac sufferer I am always looking for gluten free products. Vintage burst has given me the additional energy I was looking for WITHOUT any stomach issues or jitters. I have been using this product for about one month and have had nothing but a positive reaction. I use a lower dosage than recommended and still notice a difference in my energy level. I have been taking between one and two pills a day, usually one in the AM and one in the afternoon. Overall I am very happy with this product.I have continued to use Vintage Burst for several months now. I take 2 pills in the AM before breakfast/workout. It is great just the energy boost I need, no stomach issues or jitters.

Good stuff but too expensive!
Excellent product and it does what it should. Big pumps and great vascularity. The only reason I didn’t give a 5 star rating is because of the price. It is extremely expensive for a 30 day bottle. I get a better deal with a different product from a reputable company at a much better price.

Amino Acid Energy Booster
Vintage Burst is the perfect ‘missing’ ingredient to supplement the Vintage Build BCAA powder! I take one Vintage Burst at the start of my bicycle ride, and, on longer rides, another every hour of riding (up to 3 total), while sipping on a water bottle with a scoop of Vintage Build BCAA’s. The L-arginine in Burst adds the energy, while build (also with creatine monohydrate that helps with cellular hydration) keeps the muscles supplied with critical amino acids, and all at perfect recommended doses. Two great products that should work better synergistically. I find they work to help my stamina, especially on long workouts, and in recovery. Vintage Burst also contains Rhodiola Rosea root extract, which, according to the reputable supplement fact site Exmine.com, can help to fight fatigue, is an adaptogen, and may help with longevity. And, at worst, these are all harmless supplements, simply adding essential amino acids to my diet. But, there is clear evidence that they are much more. For additional energy (and immune support), consider adding an inexpensive 250 – 500 mg dose of DMG (N, N-Dimethyl Glycine) immediately before working out.

Great boost no crash
I cant say enough about this company. They are great. Next customer centered. This product works… Now it has a slight unpleasant smell but I think that’s from the liver. Good sustained energy and no crash. I take 2 if I need a slight boost. I take 4 if I need to really be up and engaged… I take as needed not everyday. Takes about 30 mins to an hour to kick in. I go from deathly tired about to pass out to alert and awake. It’s a subtle boost. No a jolt. It’s like all of a sudden you realize your not tired anymore…
