Clenbuterol Review, Results, & Guide For Bodybuilding 2025

Below isa summary of all the pros and cons of using clenbuterol that I’ve experienced over the years. You should absolutely not take a clenbuterol supplement, despite what bodybuilding forums might tell you, Yawitz says. J.M., D.B.J.B., J.R.K., L.F.B., T.J.V., D.A., R.J.L., A.H.C., O.G., and Y.C. R.B., G.K., M.C., and L.S.W. provided mutant mouse models and helpful advice. M.K., T.E.J., and E.A.R. supervised and performed part of the studies and provided critical guidance regarding the preparation of the manuscript.

Fat Burning

Muscle gains shouldn’t be expected, however clen may help to prevent muscle loss when eating in a calorie deficit. Increased sweating is a common reality among clen-users, especially towards the end of their cycle. This is a good sign, as it’s proof of thermogenesis (increased body heat), which is key for fat loss.

• It’s better to begin with this small dose, as easing into it reduces the risk of developing complications and side effects.
• A similar regulation of SKM pGS was observed when mice were refed after a 24 h-fasting period (Fig. 3l), indicative of the key role of SKM β2-ARs in regulating SKM glycogen metabolism in a glucose/fuel-dependent manner.
• One of the biggest drawbacks we see with anabolic steroids is the shutting down of natural testosterone production.
• People can take it orally or via injection, but both methods carry risks.

Clenbuterol + T3 stack

Fructose Somatropin also keeps your energy levels high (no falling into any food comas), which is key when cutting because this is a time when you’re more likely to feel fatigued and low on energy. If you’re serious about getting results on clenbuterol, you’ll track your calorie intake. Monitor how many you consume on average each day, and stick to this number. If you’re not losing weight after a week on the same calories, you know you need to lower this number until you’re losing weight at a rate you’re happy with. Keep in mind that the human body adjusts to the effects and can become less sensitive to it’s stimulating effects over time, so the dosage will need to be adjusted to coincide with how your body responds. This would be like jumping in the deep end of a swimming pool when you’ve just taken your arm bands off.

Your Diet

Lack of sleep will impact your results negatively and make it harder for you to recover from intensive workouts. The fact that Clenbuterol is a stimulant means you can expect a range of side effects that will impact every individual to a different extent. Some users of Clen will be significantly more sensitive to stimulant-caused side effects, while others will have a higher level of tolerance. You won’t know what adverse effects you can expect from Clenbuterol until you’ve used it. The excellent news about Clenbuterol is that it is not a hormonal compound and does not affect your testosterone production. However, suppose you (as a male) intend to stack Clen with any anabolic steroid or suppressive SARM.

As a stimulant, clenbuterol temporarily increases alertness, attention, and energy. Additionally, users may experience a suppressed appetite and improved motivation, competitiveness, and aggression while working out 51. It helps relax the muscles and airways and was originally used as a bronchodilator to treat lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). Clenbuterol’s metabolic effects will effectively be blunted if a person eats in a calorie surplus. There is generally no need to utilize this cycle (as a female) if the primary goal is fat loss, as Winstrol may compromise femininity.

So, the lower end of of the typical dosage for bodybuilders is the same as the higher end dosage that doctors usually prescribe for people with asthma. However, clenbuterol has no obvious effect on testosterone levels, thus when you finish your cycle, your testosterone levels will stay in tact. When you preserve your muscle tissue, not only are you keeping your hard-earned muscle in-tact; but your metabolism will also remain elevated, enabling further weight loss. So, it may not be wise to use clenbuterol during a bulking phase as its muscle-building effects are generally only mild. However, it does have muscle preservation effects, making it very beneficial to use during a cutting cycle. Human studies on Clenbuterol show that the supplement has a positive effect on skeletal muscle.

So there you have it, a perfect formula and affordable way to start getting shredded and try looking your best. Next, you will drop your carbs to roughly 100 grams daily and consume them in the morning and with dinner. Cutting carbs this low is not something I’d typically do right away, but it’s much easier to manage without the recovery demands of weight lifting coupled with cardio, which is why I suggest it during this phase!! I also recommend it during this protocol so your body will soak them up when you return to working out since they’ve been lowered for days.
