HR Labs has done something we’ve only seen a few other supplement companies do, and that is bring together two entire products in all of their original complexity, and squeeze them into one. The reputable brand has taken its signature stimulant pre-workout Defib and merged it with the pump and focus-fueling pre-workout Proven. They’ve always been designed to be used as a stack, although now you can get them all in the same container.
Defib Proven is the fitting name HR Labs has given its hybrid supplement, which takes absolutely everything from both pre-workouts, Defib and Proven, and combines them into one single formula. There are a few tweaks and changes to refine the experience, but it is very much everything from the two brought together for Defib Proven.
There are 3g of tyrosine, 300mg of uridine, 100mg of CognatiQ, and half a gram of citicoline to drive focus, another 500mg of the proven pump component PeptiPump. The small changes that have been made are that instead of a combined 14g of citrulline malate, it’s been brought down to a more sensible 12g, and the beta-alanine is at an even 4g instead of 3.2g. Everything else is intact, including Defib’s potent 400mg of caffeine.
If you purchase Defib and Proven separately, you’ll pay £39.99 (53.53 USD) for tubs of 20 maximum servings. With HR Labs rolling both of those supplements together for Defib Proven, the price is obviously higher; however, much more within reason than you’d expect. The cost of the joint pre-workout is £49.99 (66.91 USD) for the same-sized tub of 20 complete servings, and you can pre-order it today from hr-labs.co.uk to ship on Monday.
