Rauwolscine is a staple fat loss product for many people while dieting in order to maximize fat loss potential while maintaining steady energy levels and reducing those nasty cravings.
You can expect: Appetite Suppression, increased fat loss and a boost of energy.
Rauwolscine works by inhibiting the alpha 2-adrenergic receptors in the body. This will cause the body to release a neurotransmitter which can help prevent the creation of new fat tissue.
These Alpha 2-adrenergic receptors are very prominent in stubborn areas of the body like the inner thighs and abdominal areas, which makes the inhibition of those receptors very helpful during a diet.
In addition, Rauwolscine can help during a diet by potentially reducing your appetite and increasing energy throughout the day.
If you've dieted before, you'll know the biggest barriers are feeling hungry and lacking energy. In a calorie deficit, your body doesn't receive its usual amount of food resulting in lower energy and the release of the hunger hormone, ghrelin. Combat this with Rauwolscine during your next cut or diet.

Great selection
We can't believe the choice, quality and taste of these products. We enjoy a fun lucky dip each day to surprise us with a new flavour. Seriously not found one I don't like.
Also great for gifts. Elevates a greek yoghurt bowl or smoothie. Very happy
Ran this for the 1st time last week after buying 1 serving sample to try. Excellent pre-workout with fantastic focus and mood elevation—nothing too heavy with great pumps, but I had a fantastic workout on it, and it has quite low caffeine compared to some pre-workouts, so you feel the 100g of 2-amino more despite that being a low dose. Also, I am now going to buy a full tub; that's the beauty of being able to buy samples first.
Have used this pre 3 times now and I advise for dmba take a 8 - 10 day break between uses.
A very smooth slighly euphoric pre without overwhelming energy but more than enough even for push day. Its no drama with good endurance for sets, no heavy breathing from the alpha yo.
Bought white grape flavour. Refreshing taste and mixes well. Quite a ‘saline’ texture and mouthfeel to this one which isn’t surprising as the label is stacked. Other hydration drinks I’ve tried don’t have this. You could add more water if needed. Definitely good value for 30 servings and you know ingredients are top draw. Weigh it out as a full scoop is way over the recommended serving size.
