Old School Labs Vintage Burst: An Evidence-Based Review

Vintage Burst is marketed by Old School Labs as an “energy supplement and anabolic catalyst” and contains just three active ingredients…

Dessicated Beef Liver Powder

Old School Labs claims that Dessicated Beef Liver Powder “promotes an anabolic state and improves immune function“.  Unfortuantely, there is no evidence to back these claims up.  It’s not even clear how they came to that conclusion.

L-Leucine

Leucine is the most potent amino acid with regards to stimulating muscle protein synthesis.  It accomplishes this via activation of mTOR, a signaling molecule which directly initiates muscle protein synthesis.

Leucine is especially useful in individuals with low protein intake, as it can preserve muscle.  For those who train fasted (5-6 hours without eating), Leucine can reduce muscle breakdown without raising Insulin levels too much, so it won’t interfere with the increased fat-loss that occurs during fasted state training.

VintageBurst contains a seemingly random 625mg dose of Leucine, far less than what is considered a clinical dose.  Ideally, Leucine should be dosed between 3-5g, depending on individual needs.  So, needless to say, Vintage Burst falls a bit short here.

Guarana

Guarana is a naturally occuring source of Caffeine, but isn’t necessarily superior in any way.  In fact, given that different extraction processes may yield Guarana extract with varying amounts of Caffeine, it makes more sense to use synthetic forms such as Caffeine Anhydrous (the form generally used in studies).

Most of the time, when you see Guarana pop up in energy supplements, it’s just a way of attracting the “all natural” consumer.  It’s just marketing, not science.

That said, Guarana isn’t necessarily inferiror.  It’s still a fine source of Caffeine, capabale of providing users with energy and focus.

Is Vintage Burst Safe?

Vintage Burst is entirely safe at the recommeded dose, but it does contain Caffeine in the form of Guarana, so caution should be exercised by individuals with known stimulant sensitivities.

The Bottom Line

Vintage Burst is one of those hard to place supplements that doesn’t really fit into any one particular category.  Sometimes this approach leads to innovation, but in the case of Vintage Burst, it seems like Old School Labs dropped the ball.

There isn’t really enough Leucine to result in any sort of meaningful muscle building/preservation and a little natural Caffeine isn’t worth paying a premium for, but if you want to give it a shot that’s up to you!
