How does PhenRX by Nexgen Biolabs really work?

Ever noticed that your tummy, thighs, butt etc. are the easiest part to gain body weight? They are also the last place to lose fat. These problem areas are one of the main reasons why people enter weight loss program. Obesity is one of the most popular health conditions dealt by almost any one.

There are many prescription medications, surgeries, and diet programs that promise to help you lose weight. But their results can prove detrimental on the body especially when continued for long-term.

It is one weight loss supplement that has managed to find a place as an effective weight loss pill that works without any dangerous or prolonged side effects. In fact, PhenRX is Nexgen’s best selling diet supplement of 2016.

The company uses powerful potent ingredients that are manufactured in an FDA-registered facility. The ingredients help in increasing the metabolism rate of the body which in turn keeps your energy levels more. As a result, you burn more fat. This is one of the main reasons why many people use this as a pre-workout supplement.

Of course, the benefits don’t stop there. Once your metabolic rate goes up, PhenRX stimulates the thyroid glands that will charge the body’s fat burning mechanisms. This targets the fatty areas of the body especially the arms, tummy, thighs, etc.

Nexgen PhenRX Ingredients

Many customers believe that PhenRX by Nexgen Biolabs can deliver significant slimming effects on the body due to its potent ingredients.

  • Trimethylxanthine – in simple words, pure caffeine, it instantly boosts your energy levels to kickstart your day forward.
  • Beta-Phenylethylamine – better known as PEA, it stimulates the transmitter and improves the mood levels of the user. It is also known to enhance the alertness and focus of the user.
  • Synephrine HCL – controls your appetite and increases the fat burning tendency.
  • N-Dimethyl-4-hydroxyphenylethylamine – promotes the thermogenic process that burns the fat much more effectively.
  • Schizandrol A – a stimulant that lowers the cortisol levels and supports proportionate weight loss.
  • Yohimbe HCL – helps in breaking the lipid fats or other stubborn fat deposits. It is also an excellent herb to increase libido.

Dosage & Directions

The recommended dosage is one capsule before lunch and one before dinner. If you are an advanced user, you can take a third for additional appetite suppression.

NOTE: If you are pregnant, nursing or under any kind of medication, consult your medical practitioner before consuming PhenRX. This product is not recommended for people under 18 years of age.

PhenRX side effects

The product contains caffeine, so it’s obvious that PhenRX is NOT a side effect free pill. While there are many customer testimonials supporting its efficiency in appetite suppression and fat burning process, this diet pill is far from being a perfect weight loss supplement (but then, no diet pill is perfect…!!!)

As a matter of fact, there are consumers who have felt insomnia, jitters, headache etc. after taking PhenRX. These effects are quite common when you are having caffeine and PhenRX is not an exception. If you are not caffeine sensitive, then you need not worry much about these side effects.

However, if side effects prolong or get adverse, discontinue use and consult your medical practitioner immediately.

  • Mary J – “I have been using this supplement for three weeks now and have had major success also. I am just trying to stay lean and drop 5-10lbs. This product has already lowered my 5-7 lbs but I will still continue till I achieve my desired weight. It’s just so easy. I am not hungry as I used to be and the energy level is very strong. The patches leave a rash so I prefer the pills. Other supplements don’t even come close to as effective as PhenRX. Definitely recommended.”
