Leptigen reviews: Is it safe?

What is Leptigen?

Leptigen is a diet pill claiming to help boost metabolism while regulating blood sugar levels. While many weight loss drugs make shady claims involving clinical research that has supposedly proven the product to be effective, very few actually back up these claims with sources or links to these studies. Leptigen on the other hand, has an official website that states that studies of Leptigen’s ingredients that have actually been published in peer-reviewed health journals.

This seems to bode well for the product, but even if it has been clinically studied, how effective will it really be for you? We’ll take a look at Leptigen and see what we can learn more about what the product is really capable of. After performing extensive research our experts found that Sletrokor was the most effective weight loss pill. It’s a plant based proprietary formula backed with testimonials and positive reviews. Click the link here to learn more about Sletrokor and why it was rated the #1 diet pill.

Who makes it?


Leptigen seems to be produced by a company known as Avant Labs. However, there is very little information regarding the company available online. There does seem to be an official Avant Labs website, but navigating to the page only results in a server error. The official Leptigen website offers no information about the creators of the product, only a phone number and email is provided. However, Leptigen customer service is reportedly very good, and the company is apparently willing to distribute free trials of the product. Our experts ranked the best diet pills in a comprehensive top 10 list found here.

How (and) does it work?

Leptigen is to be taken twice daily, with or without food. However, online reviews claim that the product is more effective if taken half an hour before meals on an empty stomach.

Leptigen is a thermogenic weight loss drug, which means that it increases the rate by which your body burns fat by stimulating metabolic functions to help you continually lose weight. Better still, Leptigen claims that use of the product will not result in users losing any lean muscle mass. These results are made possible by the ingredients found in Leptigen, so let’s take a look to see what the product is made of.

Plenty of positive testimonials can be found on the official website of Leptigen, but they are possibly biased and hardly trustworthy. Positive reviews of the product can also be found elsewhere on the internet, but it seems like there are just as many user reviews that claim to be disappointed by insignificant results.  To see a comprehensive top 10 list of diet pills click on the link provided here.

What’s inside of it and are there any side effects?

Unlike many weight loss pills that come with seemingly endless lists of unpronounceable and confusing ingredients, Leptigen’s proprietary blend is comprised of only four main components. The first of these is Meratrim, a branded mixture of sphaeranthus indicus and garcinia mangostana, which are fruit and flower extracts. Leptigen claims that this ingredient has been clinically proven to be effective, even including a scan of clinical research published in the Journal of Medical Food.

However, Leptigen also contains the ingredient ChromeMate, which the makers of the product claim to be clinically proven to control blood sugar levels in the body. This ingredient has actually been dismissed by the National Health Institute as being ineffective when it comes to weight loss properties. Unfortunately, Leptigen’s claim that this ingredient is effective calls into question the other claims it makes about its ingredients.shutterstock_100295567

Leptigen also contains extracts of green tea and caffeine, both of which are known to act as a metabolism booster and appetite suppressant, respectively. It is quite likely that these ingredients are actually the ones that produce the effects that Leptigen promises are capable of helping users lose weight.

While Leptigen claims on its official website that no side effects are associated with use of the product, users have been known to experience dizziness and problems sleeping, which are most likely side effects of the caffeine found in Leptigen. Stimulant free weight loss options are available in the top 10 ranked diet pill list.

What’s good about it?

Leptigen’s official website offers a free e-book that lists 21 healthy snacks that you can work into your diet.

What’s bad about it?

The makers of Leptigen claim that all of their ingredients have been clinically proven to result in weight loss, but one of the product’s key ingredients has actually been dismissed by the National Health Institute as being ineffective in helping users really lose weight. Leptigen also fails to advertise the side effects that may result from using the product.

You can find something better on the market for the same amount of money.


1. What are the potential side effects?

Due to the added caffeine there have been customers who’ve experienced jitters, insomnia, nausea, headaches, and other similar side effects.

2. What kind of clinical studies have been performed on Leptigen?

2 studies are cited by the company which was performed on just one ingredient in Meratrim. They were funded by the makers of Leptigen which means it may be biased. No official clinical studies have been performed on Leptigen itself.

3. How much does it cost?
$109.95 plus shipping and handling for a one month supply.

4. When’s the best time to take Leptigen?
Due to the added caffeine preferably not within the time you plan to sleep. It’s advised to take 2 pills a day, one 30 minutes before a meal.

Wrap Up

Leptigen is a thermogenic weight loss drug designed to suppress your appetite and boost the rate by which your body burns fat. It claims that all of its ingredients are clinically proven to yield substantial weight loss results, but while it does provide some of this clinical research for one of its ingredients, another has been dismissed by the National Health Institute as not being an effective weight loss ingredient.

Bottom line

While there actually does seem to be some clinical research behind Leptigen, it seems odd that a drug that claims to be so well researched would include ChromeMate, an ingredient that apparently doesn’t have any effect on weight loss at all. Some people have claimed that Leptigen has worked for them, but given the conflicting nature of the product’s ingredients, that doesn’t necessarily mean that it will work for you.

In researching the best diet pills the highest rated one of 2016 is Sletrokor. It’s made up of plant based extracts which support many weight loss functions. Customers have left both testimonials and reviews on their official website. It’s even backed by a full 30 day money back guarantee with no questions asked.

    Leptigen is a border line SCAM!

    First, lets face the facts that no 2 people have the exact same body chemistry. So,what may work for you may not work for someone else. With that out of the way, I want to explain my recent situation with this company. I did the FREE trial. I was on another website looking at reviews. No where did it say clearly that after SEVEN days if not returned they would charge you $90.00! Furthermore, they did not provide instructions on how to return the product. Well, I took this product for 4 days and it did not make me feel well. Stomach was all in knots and overall I felt terrible (maybe due to my body chemistry). So I emailed the customer service about returning the product because right next to the FREE trial was a big pretty picture that says 120 DAY RETURN POLICY. So customer service emailed me back saying my reoccurring order would be cancelled. Wait…since when did my FREE trial become a reoccurring $90 order? So I emailed them back requesting how to take advantage of the 120 day return policy. I never received an email back. So I call them this morning and was told that the FREE trial DOES NOT have a 120 return policy. That the free trial was under different rules then the EXACT SAME product. The only difference according to the customer service rep is that one was a free trial, plus shipping, then after 7 days it is becomes a $90 dollar bottle. The 120 return policy product is the EXACT same but cost $109.

    What a rip off from an American Based company.

    Hope this helps anyone considering buying this snake oil in pill form.

    !!!BEWARE!!! This company is a scam…it took 7 days to receive the product from them (whoever “they” are???), which only left 7 days of the “14 day trial” period (not a fair amount of time at all, to see if the product works!)…and trust me, they debited my checking account on the 14th day! I Called “Leptigen” and spoke to rep “Meg” about receiving a refund but I was not heard and so my only option was to cancel my “Leptigen membership”…please don’t purchase this product, you’ll be sorry!!!

  3. gloria dannski says:

  5. Ann Plum says:

    Bought from their official website.
    They have fake Free trial! They give you 14 days to try it, but the 14 days begins the day you bought it. When I called – I was told I was too late to return it and they would not give me my mpney back!
    This supplement made me really sick. Diarrhea, vomiting and headaches…
    I wouldn’t recommend this supplement to anyone. Buyer beware!
