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: So far, so good! - I am a relative newbie to the PWS game, but am a seasoned athlete in the gym setting (heavy weights, powerlifting, etc). When I noticed my workouts suffering and I was struggling to make it through lifts I used to have an easy time with, I decided I needed some help. I started taking Cellucor C4, being this had the most-solid reviews I could find that wouldn't blow my mind out of the water. I am a coffee drinker, 4-6 cups per day, so I am not sensitive to caffeine. With C4, I did notice a decent "pump", and was lifting stronger and longer. It felt good! After about a month, I started to fatigue again, and don't even get me started on the crash afterward. I never did get used to the taste (only tried fruit punch), just way too sweet and made me gag. I never got a true surge of energy or the pump I was looking for, and I never experienced the "tingles" some users report. Looking into other options, I came across Old School Labs Vintage Blast. What drew me to their product was the inclusion of the "2 stages": one to get you going, and one to KEEP you going. I've been taking this supplement for about a week now, and I'm impressed! I get a better boost/pump, and am finishing my workouts stronger than on C4 without the fatigue. And I don't really crash afterward, either. A little, but that may be because I've been up since 4 am and NOTHING should be up since 4 am. The taste is spectacular - blueberry lemonade. I feel like I'm drinking an actual lemonade, not some yucky pre-workout. The only downfall is the fact you have to drink it with 14-16 oz of water, which can hit the stomach a little hard only 15-30 min prior to exercising. So far, I'm very pleased with this product and will be sure to buy again!

### ⭐⭐⭐⭐ 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!
