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.

Lovely pre this one, great for long and heavy sessions and not too jittery, posing afterwards had full muscle bellies with all the CM! Great high stim will be buying a tub,
Don't sleep on onslaught ultima, this is a strong and amazing pwo. For years I've thought UK formulas are underwhelming in comparison to the US PWO market. This is something else! Believe you me this is stronger than aby darklabs PWO i own including crack OG and Barbarian. This also dumps on any koka labs pre Ive tried including my bathtub formulas. Well done alpha neon you've out shined yourself here.
I ordered Strawberry and got Orange, opened the pack and it had clumps. Still used it and noticed the lackluster taste. The effects, which is what matters to me, was SUPERB! I mix it with my main. This product I use mostly for the DMAA and is a very good additive to my main pre workout which is Deliverance simply due to this. Half or full scoop of each and you get the perfect taste. The effects are greater than the sum of the parts. The DMAA in Firestorm really gives you that pinpoint focus while feeling this rush to get **** done. The stuff in Deliverance balances it out with even more focus and lack of jitteriness. I drink half the shake, full with water to the brim and it still tastes great and is effective.
