1.     4 Gauge (by Roar Ambition)

No-1Formulated to give you massive surges in energy, stamina and power. The makers of this new pre-workout supplement claim to have designed this supplement so you can train harder and longer, giving you even more motivation. I’m currently using this and I can tell you that I haven’t seen a pre-workout supp like this before. Every time I’m in the gym, I feel 100% motivated and this stuff is helping me train harder. 4 Gauge makes it possible to achieve that hard and dry look provided you don’t neglect the gym.

Pre workout supplements are aimed towards individuals who feel that they are dragging their feet during workouts. We’ve all been there… Still working the same weights you were months ago.

Unfortunately, most people find that they hit barriers during their training at one point or another and these barriers must be broken to really get yourself onto a new level. 4 Gauge seems to be the solution here. It provides an abundance of energy and enhances blood flow in as little as 20 minutes. This means better gym sessions more often.

4 Gauge contains natural ingredients that are designed to provide plenty of energy without exposing users to side-effects. Unlike other pre-workout supplements, 4Gauge won’t make you feel make you feel jittery, or cause you to crash, nor will it give you an itchy skin

4 Gauge is the only pre-workout supplement that hasn’t given me side-effects as far back as I can remember.

About the Company

4 Gauge is a creating of Roar Ambition, a company with a growing reputation for providing high-end, high quality all natural ingredients. This UK based company claims to be on the constant lookout for the latest developments in sports nutrition, always keeping an ear to the ground when it comes to emerging studies. The company is so keen on getting it right; they don’t appear to have any inhibitions when it comes to tweaking their formulas on an ongoing basis, even well after the launch of a product.

Roar ambition is super-honest about the ingredients they use in their products by disclosing every individual ingredient along with its dose. You’ll never be presented with “proprietary blends” with any Roar Ambition product. Proprietary blends are a great way of hiding ingredients and not fully disclosing doses. To this day I still don’t understand why supplement companies do this!
