Review: Works great whether I'm weightlifting or doing cardio! - I recently tried the Old School Labs Ultimate 2 Stage Pre Workout, and I have to say, it exceeded my expectations. This pre-workout provides an incredible surge of energy. Within minutes, I felt more awake and ready to tackle an intense workout. The two-stage formula ensures a sustained release, so there was no sudden crash afterward. Along with physical energy, my mental focus sharpened significantly. It was easier to concentrate on my exercises and stay motivated throughout the session. Overall, the Old School Labs Ultimate pre-workout is a fantastic choice for anyone looking to enhance their workout performance. Whether you’re a seasoned athlete or just starting, this product will help you push through and get the results you desire.
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.

### ⭐⭐⭐⭐ Great product, but pricey.
*by A***N on January 13, 2015*

I have been lifting weights for a little over a year. During this time, I have tried various pre-workouts...C4, The Curse, 1.M.R, ON PRE-, Arnold Iron Pump...these are just a few. Vintage Blast ranks as one of the better pre-workouts that I have used. 1. The packaging is pretty awesome. Not that that matters to anyone, but I just like it and wanted to give the company kudos for the design. It got me to stop and look at it. 2. It tastes really good for a pre-workout. Slightly chalky, but with a clear blueberry lemonade flavor. For a lot of people flavor is not a big deal. But if it is for you, trust that you will not have an issue drinking this stuff on the regular. 3. Performance is solid! The first day I only took half a scoop. The affects came on slowly. I took it about 20 minutes before I started my workout. I didn't really feel it for my first couple of moves, but by the third set (about 30-35 minutes in) I was feeling it. Definitely helped push more weight and kept me focussed. Lasted throughout my workout and beyond...about an hour. The next day I took a full scoop...and It got my motor going strong! Took less time to kick in. I started feeling it after about 15 minutes. After 25 minutes it was full on go time! Definitely did what it was supposed to do. Got me focused, got a great pump, and helped me push weight! Also, this stuff did not give me that itchy sensation (which is nice). If you take a half scoop you don't get that initial RUSH, but with a full scoop, it will pretty much slap you in the face! Now...having said all this, I don't particularly get the "two-stage" description? For me, this stuff lasted about as long as most other good pre-workouts. I would compare it to C4 or 1.M.R. for performance and lasting effect. Felt really strong about 3/4 of the way through my workout (typically a 2 hour session), but by the end...I was beat, which is stat quo. Now, I just started using this, so I cannot say how quickly my body will adapt to it. With the C4 and 1.M.R. it took about 2 weeks before I had to start using a larger dose to get the same affect...not sure about this stuff yet. All in all it is a really good product. But considering the fact that you only get 20 servings for the price, I have to give it a 4. There are pre-workouts out there that are just as good that get you 10 more servings at that price point. Now...if you care about the ingredients and the product being all natural or if you are a vegetarian/vegan, then this stuff is TOPS! Old School Labs has a great product here. If you are curious...try it! You definitely won't be disapointed!
