From the get-go, we are concerned about this product – the name seems to suggest some relation to the now-banned fat-loss drug fen-phen. This was a popular medication given out to combat obesity in the 20th century but was withdrawn when it was shown to cause chronic heart damage. Clearly, the inclusion of phentermine in a weight-loss supplement does not fill us with confidence.

If we had to leave you with a ‘take-home’ from today’s review, it’s probably the fact that fat loss and body changes should begin with the basics and not risk health any more than necessary. Losing weight can be assisted by supplements, but should focus on diet and exercise. If you’ve already crushed diet and exercise, you’re going to lose weight – supplementation of dangerous stimulants to try and ‘shortcut’ this process is just irresponsible and the long-term risks can’t be justified.
Fentermina is simply the Spanish name for Phentermine, pointing to the fact that fentermina is simply a grey market version of the classical phentermine compound, which is why it can purchased online but has no domestic retailers. Fentermine has been proven to be an effective aid to weight loss due to its stimulant effects increasing metabolism, reducing the sensation of hunger and improving fat mobilization/oxidation . The obvious problem with this is that the mechanisms for weight loss are the same mechanisms that put undue stress on the heart and arterial tissues – there is no way to gain the positive effects without also putting health at risk.
Phentermine definitely works – psychomotor stimulants increase the metabolic demands of the body through increases in homeostatic and movement-based activity. This is similar to the effects of gentler stimulants such as caffeine, which increase NEAT (non-exercise activity thermogenesis), elevate heart rate and increase the energy usage of various tissues in the body. However, the effects of phentermine are far more severe in both its benefits and detriments: the increased coronary activity increases the number of calories that we burn, but it also places undue stress on the heart and vascular system, leaving lasting damage on the tissues.
We’ve covered phentermine and related stimulants in previous reviews, but the important point to note is that the difficulties of phentermine are not associated with being ineffective, but being dangerous. The trade-off of fat loss to heart damage is not reasonable or justifiable. Follow up studies to the ban of fenfluramine-phentermine found that 30% of users still suffered from aortic valve damage 2 years after they stopped consuming the drug – this suggests to us that there are serious medical concerns for those who have used this compound. This contributes to the occurrence of life-threatening conditions such as stroke, arrhythmia, heart attacks/failure and coronary heart disease [2-5]. These are some of the most common killers in the US and increasing our risk is not a good thing.
Supplements should aim to improve health and reduce the risks of death, in our opinion, so we can’t take Phentermina seriously as a supplement for health, fitness and obesity. Especially when we consider that the risk of heart failure about equivalent between those who have used phentermine (and achieved a healthy BMI) and those who are morbidly obese. In these circumstances, a fish oil supplement would be infinitely more beneficial to health and wellbeing than phentermine!
Many of the customer reviews suggest no negative health risks or side-effects, whilst others report serious side-effects being present from early in the use of Phentermine. The problem with this is that, firstly, the side-effects are incredibly severe when they do occur. Secondly, and more worryingly, the effects on the heart are not likely to be felt other than through raised heart rate – how does it feel to be suffering from long-term aortic valve damage? These side effects may not be perceptible whilst taking the drug, but that does not mean that they are not present.
Logistically, fentermina is also difficult to acquire. The fact that it has been banned for human consumption in the US has made the online market unreliable and fiddly. There are very few direct retailers available – with most websites providing the drug through dubious channels, crossing national borders, and charge around $100. Purchasing this product locally through a pharmacy is far cheaper, though the obvious problem with this is that it requires travelling to Mexico or south America in order to obtain legally.
One of the problems that we’ve seen with the black market nature of this product is the inclusion of a number of illegitimate, under-dosing or purity concerns. People who are buying phentermine are coaxed into believing that their product is pharmaceutical-grade (and in many cases this is true), but often this is not the case and under-dosing and ‘cutting’ with other substances remains common.
There are conflicting reports about the value of this product – whilst we cannot recommend its use in light of the health risks that it poses to customers, there are many reviews that suggest that the effectiveness of the product is simply enough of a priority for them to justify the cost. Whilst there are many supplements on the market that are ineffective and have similar price points (we have reviewed many of these), they do not deliver the same effects. From a value perspective, this may have one of the highest value per dollar, simply because it does what people buy it for.
The difficulty with analyzing market alternatives for this product is that they are all (1) less damaging to the body, but also (2) less effective. When looking at fat burners, we are usually struck by how ineffective they are and how little they can actually improve fat metabolism. This isn’t a concern with phentermine, as the effectiveness of the product isn’t a major concern. Weight loss is far more likely when consuming the product, but so are chronic health problems.
As far as market alternatives go, there are almost none. The only reasonable alternatives to a heart-damaging stimulant are other, equally-worrying heart-damaging stimulants. When we look at products containing sibutramine or ephedrine-derivatives, there are similar effects at similar prices with similar risks. Any reduction in the effectiveness of a stimulant like phentermine is accompanied by a reduction in the severity of the risks and health effects, suggesting that there will always be a serious trade-off between the two.
Comparing phentermine to other market alternatives – such as traditional fat-burner supplements – is just uninformative. The differences between these two styles of product are so vast that it’d be equivalent to comparing dietary fiber with insulin for relieving diabetes. There are no reasonable comparisons to draw: phentermine is a medical-grade obesity intervention and has huge side-effects, whereas most of the conventional supplements have tiny effects and no side-effects.
Overall, the value for the product will vary by dosage and your personal appraisal of how important heart health is in comparison to fat loss. Whilst some individuals did not suffer any notable side effects, the risk of heart problems is considerable and cannot be overlooked. We do not recommend this product – establishing value when the ‘cons’ column includes your health is never easy – but the prescription-only use of this product suggests that there are some circumstances where it may be used to benefit health rather than damage it.
For the general public – those who are simply looking to lose weight and improve their shape – we cannot recommend this product. If your diet and exercise are not perfect to begin with, then phentermine is absolutely not how you should address the problem – diet and exercise are a better prescription and will be health-promoting rather than dangerous. If you are eating well and exercising regularly, then there is perhaps even less need for phentermine, as weight loss is inevitable and is likely to be of even higher quality.
We’re not sold on fentermina/phentermine – as a compound it has been linked to some of the worst medical scandals in the past 30 years and heart health is such a significant concern already that adding to this strikes us as both unnecessary and irresponsible. The use of serious psycho-motor stimulants for something as simple as weight loss just isn’t something that we can justify.
Buying phentermine is both difficult and costly, with various reports of acute (headaches, dizziness, heart palpitations etc.) and chronic side effects (heart damage). Logistically, this is not an easy compound to use or purchase – for those who are determined to acquire and use this product (for some reason), it will cost large sums of money on a monthly basis and the actual purity/dosage of the product will vary by supplier and how legitimately you can buy it.
Overall, it would be irresponsible of us to recommend this product and we can firmly state that we are against the use of this product and rate it at 1/5 for the severe and high-frequency negative side effects.
