Being made by Generix laboratories isn’t a good start to the whole process of marketing your product as a non-generic fat burner. Sadly, it’s exactly that – a proprietary blend of relatively underwhelming compounds that have been marketed as being a scientific breakthrough or anomaly when, in reality, it’s going to be about as effective as any other generic pill.
Obviously, this involves a stimulant but nothing particularly dangerous or effective. As with many fat burners, we find that there are two categories: effective but dangerous, or totally innocuous. Lepto falls into the latter category, being a mixture of amino acids and other low-effect compounds, as well as caffeine.
There are a few problems with this that we’ll get into later, but for now, our first impression isn’t particularly positive. It strikes us as being another product being sold on the suggestion that it’s going to boost metabolism. It’s not sold on its ingredients, but the promise of fat loss to desperate, unsuspecting consumers.
What is Generix Leptopril?
Marketed as “acute metabolic regulator”, you might expect something cool and science-y. Rather, what you’re going to get is a herbal compound with caffeine and a few other mildly-effective compounds that are easily outpaced by simple things like a small change in sleeping or eating habits. Let’s talk about this term though, as it brings some clues.
First, the fact that it is acute is one of the most important things to note. When we look at different compounds that are associated with weight loss, they’re consistently short-term in their effects on the body. This is true of everything from caffeine to capsaicin. The problem is that for most compounds this isn’t enough time to have a real effect on long-term fat loss and maintenance.
Acute means short-term and this is the problem. Short-term approaches to long-term problems always fail eventually and the use of any acute management of weight overlooks the risk of chronic bad habits and inactivity. Dealing with this problem by taking a pill – effective or not – is a real problem and is probably at the root of the obesity ‘epidemic’.
The fact that this pill is unlikely to do anything is another consideration, but not as interesting to think about!
Does it Work?
We’ve probably already given you the heads-up that it’s not going to make much change to the way that your body looks or feels. This is a statement that needs explaining. We’re going to go through the biggest ingredients and why they’re not quite as effective as you might like to think.
We love caffeine – it’s widely associated with great health and lifestyle benefits, as well as being the perfect low-level stimulant for weight loss . It’s healthy and effective without bringing any appreciable problems – not comparable to existing “fat burners” like phentamine, at least.
This is a great compound to have in your fat burner but crucially, there’s no need to use a supplement for caffeine. There are countless caffeine products on the market such as coffee and energy drinks that are less expensive and taste way better.
That being said, caffeine does have positive short-term effects on metabolism and there are estimations that it might provide around 100 calories a day of extra fat burning capabilities to ensure that you’re losing weight. Combined with other benefits, it’s a great way to improve your overall athletic performance and body composition.
Green Coffee Bean
Green coffee bean is an extract used to provide chlorogenic acid – a compound that has been shown to associate with increased fat oxidation (in mice, not humans, so we can’t make assumptions) and it even has potent antioxidant properties .
However, correlations with fat loss are very small and often unreliable. Consider how caffeine causes approximately 100 calories of difference (a relatively huge amount), while chlorogenic acid has failed to reliably show 10% of this. You’re not going to see huge effects and there’s already a concern with the reliability of these outcomes.
Simply put, don’t expect much from this one – especially since the proprietary blend stops us from seeing just how much of anything this product contains.
Green Tea Extract
This is another ingredient that has been misunderstood – with a variety of problems associated with the dosage and effectiveness of the compound. Green tea extract’s main active component is EGCG – a catechin that increases catecholamine concentrations and enables fat loss.
The problem is that it takes a huge amount to see much benefit , with around 5g of fat being burned by a full day of consistent tea-drinking. The superior alternative to the extract (which we know is not heavily dosed based on the overall amount of prop. Blend) is probably just a matcha latte here and there.
You might be able to metabolize a small amount of fat using this, but it’s probably going to have less long-term effects than say an hour of extra sleep every week. The difference really is obvious and, even in combination with the other stuff in this supplement, it won’t be worth your money.
This one is a weird inclusion, as it doesn’t have any reliable effect on weight loss at all, but has a great effect as an aphrodisiac and in the production of sperm or breast milk.
The only conceivable reason behind this is that Forskohlii and many others (such as Tribulus) are involved in the increase of libido in an attempt to seem like a testosterone booster. There are some positive mental effects associated with this, but they’re only similar and the actual benefits aren’t remotely significant.
You’ll see changes in testosterone, but you’re not going to see real-world differences in the benefits like fat loss and muscle gain that you’d see with a steroid or similar compound .
If you’re looking to conceive a child or improve your sexual health then go for it, but this doesn’t have any real fat burning benefits. We’re just confused.
The rest of the compounds in this supplement are herbal supplements that have very little reliable, credible, unbiased evidence.
This is the problem with a supplement like this: the ingredients are herbal remedies that are either reliably ineffective or reliably innocuous. There are very few exceptions to this rule and, in the short-term, we don’t see there being much benefit.
Disclaimer: it’s totally possible that there might be some huge scientific breakthrough about any of these ingredients that prove it makes you a big, shredded stud. However, we’re not going to speculate that far – the current science says they’re all a bit undecided.
The problem with this supplement is one we see often: it’s not made up of effective compounds, and what it does have is widely-available on the market in purer, better forms or simply at a lower price.
When we look at the active ingredients, they’re caffeine, green tea, and green coffee bean. The difference with other products on the market is that they often include far more effective and useful additions. While the Amino acids in this product are relatively useful, they’re not necessary and they’d be much better replaced with important vitamins.
We’ve seen this used before in compounds that include B12 and Vitamin D in high-absorption forms and have a varied field of use. As it stands, this product isn’t bad but it’s far from stand-out. It’s clearly inferior to a number of alternatives, even if the price point is only around $40.
We’d give it a 3/5: we’re not excited by it, but we’re not particularly worried about it. If it’s the best price you can get on a product of this nature and you’re determined you want one, it’s a tolerable choice.
