HR Labs



Our brand’s strapline is ‘Made For Progress’ for good reason. We are always striving to do better - in the gym, in business, in life – and we know the likelihood is, that if you have found yourself here, you are too.

Enter Defib V2 – everyone loved the original, but we knew we could do better and we have. A few subtle changes that make a BIG difference. More Pumps, More Energy, More Focus.

Defib redefined the pre-workout category. With V2 we’ve levelled up!

Defib V2 is bringing it, no question. Legitimately one of the most complete daily drivers on the market and we’ll call it now, THE best tasting. A bold statement for sure but one that we feel is totally justified. We’ve taken a multi-faceted, synergistic approach to the pre-workout conundrum and cracked the code!

In a category littered with thoughtless, dated formulations, cheap under-dosed and ineffective products take up way too much shelf space.

…But thankfully, we ain’t all in it for the money! A few brands do it right and do it well and we like to consider ourselves to be one of them. Defib V2 was designed by people that train, for people that train. We only formulate products that we are excited to use ourselves!

Defib V2’s research driven formula utilises optimal doses of effective ingredients, is fully transparent and highly effective. Made for Progress!
