Rx Labs Oxy XR is one of the best-functioning supplements supporting fat burning. Rx LAbs is characterized by the fact that the supplements introduced on the market are based on the cult formulas improved by RX Labs scientists, which makes the products unrivaled. Oxy XR, through the use of appropriate ingredients, effectively blocks the appetite for sweets and stimulates, which means that despite the supply of low calories, you have much energy needed in everyday duties and during training.


Already after the first portion of the Oxy XR, you will feel an increase in energy so that you can conduct long and incredibly intense workouts. Oxy XR quickly and permanently burns fat in several ways. First, it speeds up the metabolism. Secondly, it increases the intensity of training, suppresses appetite, raises the level of noradrenaline, and as a result - thermogenesis (heat production) in the body increases. It releases free fatty acids from fat stores, thanks to which they can be burned and converted into energy. Oxy XR directs the body to burn fat as a source of energy. Another plus is that Oxy XR stimulates the production of serotonin, which improves the mood. These are just additional benefits; We remind you that the main advantage is of course, the possibility of burning fat in the most stubborn places.


To sum up, Oxy RX is a body fat burner with the most effective composition, which will allow you to quickly get rid of unwanted body fat from resistant parts of the body. Thanks to exerting an appetite-suppressing action, it is intended mainly for people who have a problem maintaining the imposed dietary regime.

Ingredients


Caffeine Anhydrous


has a thermogenic effect and suppresses appetite, thanks to the increase in adrenaline and norepinexxrine production. It has been proven that it causes the formation of such neurotransmitters as dopamine, acetylcholine, or even serotonin in the central nervous system, which exerts a stimulating effect and increases cognitive functions. The overall caffeine activity on the body allows you to maintain training effectiveness and maintain a festive mood, despite the calorie deficit.

1,3 Dimethylamylamine


– A very strong stimulant. It stimulates the process of reducing body fat and helping to increase the intensity of training.

Cao Mahuang Extract


– Stimulates the nervous system and improves the function of beta-adrenergic receptors, releasing fatty acids, which leads to increased lipolysis and release of energy and increased heat production.

Bauhinia Purpurea 10: 1


– This is a plant from the Far East, used for centuries in traditional folk medicine. It promotes the processes of fat reduction by stimulating the thyroid to increased T3 and T4 synthesis. It also has a positive effect on the well-being and helps regulate the blood’s lipid profile. It also has antioxidant properties. Research is also being carried out on this plant due to its anti-cancer potential.

Bacopa Monnieri 50%


– This is, above all, significant support for the nervous system. Bacopa Monnieri improves brain function, including through the synthesis of proteins. This leads to improved intellectual functions, improvement of memory and concentration, and improvement of the body’s cognitive processes. Bacopa Monnieri can reduce stress caused by intense mental effort and too many tasks to do. It allows you to relax and give the brain a rest. The product is recommended for people who are forced to do intensive mental and physical work every day.

Ashwagandha 2.5%

It effectively reduces the cortisol level, which noticeably facilitates adipose tissue reduction and preservation of the aesthetic silhouette.

Cirsium Oligophyllum


– Naturally occurs in Eurasia, North America, and North Africa. According to recently published scientific studies, extracts from this plant can intensify lipolysis processes while at the same time inhibiting the deposition of adipose tissue in the body. Cirsium Oligophyllum is a source of flavonoids: Neptune and hispidulin. It also has antioxidant properties. In the sports supplementation, it is used because of the effect on the reduction of adipose tissue and synergistic action with other ingredients, such as, for example, caffeine.

"persistent fat" like the belly (thigh), thighs, or buttocks. The most important effect of applying Aphrodyne HCL is the precise degreasing of the body in places where it is tough to get rid of it due to low blood supply.
