Drenbuterol is a fat burning supplement that claims to burn fat and increase thermogenic processes, such as metabolism and energy, through its patented formula of caffeine and proprietary blend of Yohimbine HCI and Beta Methoxyphenylethylamine. Claiming to be a safer and more potent alternative to Clenbuterol, it says it has the same effects while providing safer ingredients that are proven to boost thermogenic processes and give the dieter a sense of euphoria. One dose of Drenbuterol is to be administered daily, and their company does not recommend taking it more than once daily or taking other supplements or stimulants.

Drenbuterol is mainly marketed towards bodybuilders who want to cut fat and is heavily discussed on bodybuilding message forums and websites. Supplement stores and online retailers sell Drenbuterol for fairly cheap at about $24.00 per 30ct bottle. Although smaller sizes or samples are not offered, a short money back guarantee is offered to unsatisfied customers. Let’s evaluate Drenbuterol’s formula.


Mesolimbic Beta Agonist Complex: Caffeine, L-5 Hydroxytryptophan, Beta Methoxyphenylethylamine and Yohimbine HCl).

Other Ingredients: Yellow Opaque Gelatin Capsule, Maltodextrin, Silicon Dioxide and Magnesium Stearate.

Product Features

Drenbuterol’s first ingredient is Caffeine, followed by a proprietary blend that features Yohimbine HCI. Both ingredients may present their own issues and side effects. Caffeine, a stimulant that decreases fatigue signals in the central nervous system, works mainly a diuretic and may temporarily increase energy levels. It also increases heart rate and nervousness however, and in larger doses may cause dehydration. Because of its impact on the heart, it is often not used by people with persisting heart conditions.

Yohimbine HCI is an extract from yohimbine bark, native to western Africa, and although it is considered similar to Yohimbe, it is not the same extract. Yohimbine HCI’s main difference from Yohimbe is the level of yohimbine chemicals present in its bark. It contains negligible amounts. Therefore any benefits may not be as evident in this extract, which may include the ability to reduce fat if used in conjunction with exercise. This may also reduce the side effects associated with yohimbine, including rapid heartbeat, nervousness, and dizziness. Still, both ingredients present numerous heart-related side effects, but it may help ward off drowsiness and fatigue. There is no evidence it may increase metabolism or increase positive endorphins in the body, however.

  • Contains stimulants which may temporarily increase energy.
  • Is an affordable fat burning supplement.


  • Does not contain any ingredients that are shown to increase the metabolism.
  • Caffeine may cause dehydration and increased heartbeat.
  • Similarly, Yohimbine HCI may cause increased heartbeat, dizziness, and nervousness.


Drenbuterol claims to be a safer and more potent supplement than Clenbuterol, but their ingredients only offer few documented benefits to bodybuilders and dieters. The heavy use of Caffeine may be a concern for those with heart problems, as this stimulant may increase symptoms related to it. It is a cheap supplement despite these concerns, however, but dieters should be careful with this supplement.

    I bought this product about 4 years ago when it wasn’t so noticeable. The price for it I believe was around $49.99. While reading most of your comments, I can maybe answer some of them.

    I’ve noticed people getting sick after eating because they took Dren. It isn’t your typical fat burner. I took it once without eating and it was the worst idea ever. I felt like vomiting and saliva kept coming out of my mouth in large quantities. With the experience I had, Dren should be taken before a workout (preferably an intense one). This fat burner really works. After running 6 miles I managed to shave off about 4 lbs. Is that a safe weight loss ratio? No, its not. Which brings me to my second point; Dren should be taken every other day because of how powerful it is. You should not mix it with other suppliments i.e Pre workout, other fat burning products. If your pregnant or have serious heart, or blood related problems/illness, I highly recommend that you DO NOT take Dren as it increases your heart heart. Now, this was about a while back ago, I don’t know if they changed it or if its still the same but I hope it helps.

    You only talked about the caffeine and Yohimbine. What about the Beta Methoxyphenylethylamine? The chemical diagram is on the front of the box, so to me that indicates that it is the “main” ingredient. Do you have any information on this?

    I have used Drenbuterol for 2 days and I am experiencing nausea. Has anyone else had this side effect? Is it the caffeine causing this?



    I’m on the first day and have felt nauseous all morning..

    Please be carefull using the product DREN. After 13 days on it my husband had a stroke. We cannot prove this is what it was from but all the reactions he had are all gone now that he has stopped using it. the doctors could not even explain why he had a stroke. fortunatly he is totally rcovered.

    when should i take dren….what time of the day



    I take it usually first thing after eating a semi small breakfast..but I think it depends on each persons body, I don’t get jittery or the awake effect doesn’t last that long on me. I would say start early and try to work around it if you crash to early. Towards the end of the month cycle the pills had no effect on me. I had to take two just to keep myself from crashing and I was having more cravings. I lost about 10 pounds off it with just dieting and running and then 15 on it with the same plan. Currently taking a little stronger pill that’s having zero effect other than sweating a lot more. I bought another months supply of dren hoping I can shed another 15.



    Thanks for the comment. Question: what kind of pill are you taking now? with zero side effect?




    Mike, answered?
