Review: Clean, sustained energy & focus - I'm a person who has switched between different pre-workout supplements over and over again. Some left me feeling too jittery, to the point whereI became nauseated & it was difficult to focus on my workout. Others became weak over time as I built up tolerance to them. All the while, I hadn't been paying too much attention to what I was actually putting in my body. Many of the pre-workout supplements on the market are not much more than an overload of caffeine and beta-alanine which gives you a temporary rush of energy, followed by a major crash. In addition, the majority of them contain proprietary blends, meaning you don't truly know the amount of each ingredient. In my search for a "cleaner" pre-workout, I came across Vintage Blast. The price was right, there were no proprietary blends, and it had a great ingredient profile. The main ingredient is L-Citrulline Malate, which has been shown to improve blood levels of Arginine even better than supplementing Arginine itself. It also contains D-Aspartic Acid, a natural testosterone booster. I used the product for the first time today, and felt a world of difference compared to the pre-workout supplement I was previously using. Upon taking it & driving to the gym, I felt no jitters or uneasy feeling which is something I was used to with all pre-workouts. Once I stretched out and was ready to begin excercising, the energy and focus was there. After about 45 minutes, I still had a sustained level of energy, but would get additional "bursts" which I assume is the 2nd stage taking effect. I was able to push my workout harder with shorter rest periods in between. Vintage Blast is an excellent pre-workout that tastes amazing, and Old School Labs has undoubtedly gained my trust as a consumer. I look forward to trying out the rest of their product line.
Review: Surpassed my expectations!! - I rarely write reviews but when something is absolutely great then I think it's worth a share. I sampled two other brands from a local store and almost concluded that preworkouts weren't for me since I've never tried them. One had no increase in energy and came with a stomach ache. Both gave me tingly face and that was highly annoying b/c I didn't know what was going on. First timer with preworkouts I went out on a limb and ordered vintage blast without sampling and I'm beyond pleased. I'll start with the texture/and flavour. The taste is FANTABULOUS (fantastic/fabulous). I was like wow what a treat, I think I entered a high from the taste alone. It's the most wonderful lemonade with a hint of blueberry that you'll ever taste, it mixes effortlessly as well. I threw mine back about an hour before my workout. Entered the gym and now it's time to go at it. I start with 4 sets of walking lunges and I'm sometimes weak by the second rep. I also add 30lbs total, dumbbells to intensify things. Well on the second set I looked at my legs like I must not b doing something right. I finished the last set and had no burn when I normally feel it around the 2nd set. I would guess and say 20 steps equal 1 set. So I'm impressed and on to squats. Well I'm psyched and sd this is the day that I'm gonna see if I can improve. Well I did and impressed myself with my first two sets of 140 squats. Yay me. On to leg press, knocked out with ease, no burn. Deadlifts, I always feel those but increased my weight by 10 for a totally of 75 lbs I think. I'm stoked!! Then I increase my cable kickbacks and on to extensions, curls, abductors and adductors. Never finished a leg routine with so much energy. I was super excited and knew that my future workouts would only improve things. Next day was shoulders, back, and biceps. I'll spare u the routine but I do about 16/17 exercises. So I'm there for a whole. I increased the weight on several and finished surprisingly strong. Been in the gym for almost 4 months, only been working out for a year. OVERALL: this product is great, no tingly face no rush, just this unexplainable energy like you've been renewed and ready to work. Absolutely no comedown and I slept as usual. Thanks for making an awesome product and I'm looking forward to trying others.

### ⭐⭐⭐⭐ An honest, non-gushing review
*by K***T on January 26, 2017*

I'm leary of the high praises people give supplements, especially pre-workouts. After lifting and having an intense fitness regimen for 15+ years, I've learned there is no magic pill or powder to change a person's physique or motivation: it only comes with hard work and self-discipline. Pre-workout is simply a small part of the game, and isn't necessary. However, they do give an edge in energy and focus, so they have their place. People are devout to the pre-workout of their choice, even if they don't know why or haven't tried others. You get a good feeling with one type and you feel like you can't go without it. I was devout to N.O. X-plode for a long time. But I like to mix it up and decided to try something else. With that, Vintage Blast works extremely well. I have tried a lot of pre-workouts, and this one gives me the energy and focus to workout all the way through tough days and still feel it afterwards. I don't get the itchy, crawly sensation as I did with other pre-workouts. I also don't get the post-workout crash where I have to sit around after a solid workout, which defeats the purpose of wanting to be active. And the flavor is really good, if you like sour lemonade. It's like a cheap, acceptable version of Country Time Lemonade mix, flavor-wise. Unfortunately, there are two reasons why I couldn't give this product a five-star rating: price and texture. The texture isn't a major issue because I've had worse; but it is gritty and doesn't completely mix, leaving the last few sips fulls of grit. It's like drinking a lemonade at the beach when people are flinging sand everywhere. Also, $39.99 for 20 servings is the most expensive pre-workout I've purchased. C4 and N.O. X-plode are cheaper per serving and the price is a huge consideration for me. I'd rather spend my money on life than a non-essential drink. There is no reason a pre-workout should cost $40 for less than a month worth of use. I don't see extreme benefits of this pre-workout that justifies the price. I can still use N.O. X-plode and get the same workouts and gains for half the price. I may buy Vintage Blast again but it will definitely not be my staple pre-workout. If the price would come down to the same price per serving as C4 or N.O. X-plode, I would definitely convert to Old School Labs as my go-to supplement. But I definitely like the feeling better than any other pre-workout. But just because I enjoy driving a Cadillac best, doesn't mean I am going to buy it when I can only afford a Honda. **Update** After my review, Old School Labs customer service contacted me regarding concerns and issues about the product. It is without a doubt that they stand behind their products and want to make sure they are working. I was very impressed with their customer service, and their willingness to discuss any issues. You can't go wrong with Old School Labs, as long as you can afford it.
