By spring, both the performing athletes and amateurs without any big stage ambitions face the same question: How to get rid of the off-season fat? Yeah-yeah, diet, cardio, hydration, and so on… But what if you want to get the 6-pack faster? To answer half of all the questions, you can buy Clenbuterol, Yohimbine and Ketotifen in our store (all lab-tested and made by a trusted lab, we don’t sell any BS). Here’s how the compounds work together and why you may want to give this trio a try.
What is Clenbuterol and How it Works
Clenbuterol is probably the most effective non-steroidal and non-hormonal compound one can use for weight loss.
In short, Clenbuterol is a beta-2 agonist. It affects the beta-2-adrenergic receptors of the presynaptic membrane and promotes the release of norepinephrine and adrenaline increases, which have a powerful fat-burning effect.
Clenbuterol increases the basic metabolic rate by 20-30% of the natural level.
Clenbuterol reduces the activity of lipoprotein lipase (LPL), making fat storage less efficient—but it doesn’t make fat gain ‘impossible.’ Caloric surplus still wins. Clenbuterol may also influence thyroid hormone conversion (increasing T3 levels slightly), contributing to its thermogenic effect.
Sounds impressive? However, there is a stack that can make Clenbuterol even more effective — for absolute fat-melting results. It’s Yohimbine and Ketotifen.
What is Yohimbine
Yohimbine is a substance from the alkaloids class. All alkaloids have a specific effect on the human body: they anesthetize, narrow or dilate blood vessels, stimulate or inhibit the activity of the central nervous system. In small doses, they act as medicines. In large doses, they act as poisons.
Yohimbine promotes weight loss by affecting the alpha 2-adrenoceptors, which block the release of fat. It acts in 3 separate ways:
- By blocking alpha-2 adrenoceptors (which are concentrated in stubborn fat areas like lower belly, hips, and thighs), yohimbine helps mobilize fat from these otherwise resistant regions;
- By enhancing the synthesis of adrenaline and norepinephrine, it activates the process of burning fat for energy production;
- In addition, yohimbine increases thermogenesis – converting fat molecules into heat.
In a stack with beta-2 agonist Clenbuterol, alpha-2 antagonist Yohimbine leave pretty much zero chances to your fat tissue.
Why You Need to Add Ketotifen to The Cycle
In short — because your body gets used to Clenbuterol easily in roughly 2 weeks and stops responding to it.
With the prolonged use of Clenbuterol, the response of beta-2 receptors to stimulation will decrease inevitably. 2 weeks pause in the cycle and taking the antihistamine compound Ketotifen, which has a regulatory effect on beta-2 receptors, helps you “refresh” the receptors.
Clenbuterol Ketotifen Yohimbine Cycle — 5 Things to Know
While it may sound easy and safe (since you take nothing steroidal, nothing hormonal, and just affect specific receptors in your body), this extreme weight loss cycle still demands some caution and precision. Here are the general recommendations:
- The very first warning is — don’t rush. Unless, of course, you are trying to experience all the possible side effects inherent in these two drugs. Take just a few and wait — see how your body will respond to the compounds;
- Start with the minimum dosage — 20 mcg for clenbuterol, for yohimbine – just 5 mg will be enough for starters. If you want to raise the dose — do it gradually. Most users stay within 20-80 mcg for clenbuterol and 5-20 mg for yohimbine. Going higher increases side effects significantly without proportional fat loss benefits. Listen to your body—more isn’t better;
- Take both compounds in the morning only. A sleepless night is guaranteed if you’ll take any of these compounds in the afternoon. Both promote the Adrenaline production — which is, quite literally, the opposite of a good night’s sleep;
- Don’t abuse Clenbuterol and make all the necessary pauses. By analogy with the schemes for taking clenbuterol, yohimbine requires breaks as well: 2 weeks on, 2 weeks off;
- No coffee or other drinks containing caffeine while you’re on Clenbuterol and Yohimbine. Of course, the same goes for alcohol. Your body experiences enough stress because of your diet and Clenbuterol — don’t add extra pressure on it with booze or drugs.
Clenbuterol Cycle Side Effects
Luckily, MOST side effects are dose-dependent, so you’re relatively safe if you won’t abuse Clenbuterol or Yohimbine. However, SOME of them still can manifest, and you should be ready. Here’s what you can expect:
- Tremor;
- Insomnia;
- Elevated blood pressure;
- Sweating;
- Nausea;
- Nervousness;
- Panic attacks;
- Easier irritability;
- Increased motor activity;
- Abdominal pain;
- Diarrhea.
Yup, that’s a big list of things you probably don’t want to experience. In order to avoid them — keep your doses low, maintain a healthy lifestyle in general (at least while you’re on cycle), and follow the 2 weeks on – 2 off protocol.

Clenbuterol + Yohimbine + Ketotifen Stack (Dosing Guide)
This stack is often used during cutting phases to increase fat loss while maintaining energy and training intensity. Clenbuterol boosts metabolic rate, Yohimbine helps mobilize stubborn fat (especially during fasted cardio), and Ketotifen helps restore beta-2 receptor sensitivity so Clenbuterol keeps working.
The protocol below shows a simple 8-week structure that allows you to increase doses gradually while giving your body time to reset.
Example 8-Week Protocol
| Week | Clenbuterol | Yohimbine | Ketotifen | Notes |
| 1 | 20 mcg | 5 mg | — | Test tolerance |
| 2 | 40 mcg | 10 mg | — | Increase if sides are manageable |
| 3 | 60 mcg | 15 mg | — | Monitor heart rate and sleep |
| 4 | 80 mcg | 20 mg | — | Peak dose |
| 5 | — | — | 1–2 mg | Receptor reset |
| 6 | — | — | 1–2 mg | Continue recovery |
| 7 | 20–40 mcg | 5–10 mg | — | Restart at lower dose |
| 8 | 40–60 mcg | 10–15 mg | — | Increase if tolerated |
Key Dosing Rules
1. Take Stimulants in the Morning
Clenbuterol and Yohimbine stimulate the nervous system. Taking them late in the day often causes insomnia.
Best time: morning, ideally before cardio.
2. Use Yohimbine on an Empty Stomach
Food — especially carbohydrates — reduces Yohimbine’s effectiveness.
Recommended timing:
- Take Yohimbine 30–60 minutes before fasted cardio
- Eat your first meal after cardio
Clenbuterol can be taken with or without food.
3. Take Ketotifen at Night
Ketotifen can cause drowsiness, so it’s usually taken before bed.
It may also help offset sleep issues caused by Clenbuterol.
4. Respect the Receptor Reset
Beta-2 receptors become less responsive after about 2 weeks of continuous Clenbuterol use.
The 2-week break with Ketotifen helps restore sensitivity so the next cycle remains effective.
The Conclusion
Stacking two extremely powerful fat destroyers in one cycle has both benefits and risks. You need to stay extra cautious and watch out for the red flags.
Full-scale preparation for this type of cycle should start even BEFORE you start taking any of the compounds: you need to do a full medical check and make sure that you don’t have any heart issues or other pre-existing health problems.
Also, remember that the use of these medications is intended for people who exercise regularly. Of course, with a sedentary lifestyle, the effect of Clenbuterol and Yohimbine will be notable, but it will be extremely far from what you’d get if you were exercising on a daily basis.
