Clenbuterol Cycle


A Clenbuterol cycle is for the most part, very simple and straightforward. It does not matter if the user is a beginner, intermediate, or advanced, Clenbuterol cycles and the manner in which it is cycled generally remains the same across the board. The reason this is so is because Clenbuterol is not an anabolic steroid, but instead is a stimulant – a sympathomimetic fat burner. It is for this reason that its almost singular purpose is that of fat metabolism. Even though it is a stimulant, these stimulant properties are not favored nearly as much as its fat burning characteristics. The reason why is because Clenbuterol’s stimulant effects (energy and alertness, for example) are not as prominent or effective as other stimulants available, such as Ephedrine. Instead, what remains is Clenbuterol’s primary purpose as a fat loss compound, and Clen cycles should be treated as such. Clenbuterol can commonly be seen stacked with other compounds, such as anabolic steroids, for the purpose of enhancing the fat loss effects through its combination with anabolic steroids’ nutrient partitioning abilities. Other compounds commonly stacked in a Clenbuterol cycle is T3 (Triiodothyronine), which is a substance commonly used alongside Clenbuterol. T3 is synthetic thyroid hormone, and T4, which is a different type of thyroid hormone that is synthesized by the liver which ultimately gets converted into T3, is also a commonly stacked drug with Clenbuterol. T3 and T4 are very strong fat loss compounds in their own rights, and when combined with Clen, the stack can elicit dramatic fat loss in many people. Although these two compounds are potent fat loss agents, they will not be discussed in this profile.



Individuals who wish to run Clenbuterol cycles that include the use of anabolic steroids are usually seen stacking Clenbuterol with certain anabolic steroids that are commonly known as being highly suitable for ‘cutting’ cycles and periods of fat loss. The point in such a practice is that the particular anabolic steroids that do not promote water retention or fat retention/gain (as a result of Estrogenic activity) will develop a lean ‘hardness’ to the physique perfect to accompany fat loss phases. The typical commonly used anabolic steroids of this type that are usually stacked with Clenbuterol include: Tren, Winstrol, Masteron, Anavar, Turinabol, Primobolan, and Testosterone (which should for all intents and purposes act as the base compound for any cycle). What will be displayed now are the most common samples of a Clen cycle are what would be commonly stacked with Clenbuterol in a given cycle. A critical note that has been mentioned previously which must be remembered is that in all of the following listed example Clenbuterol cycles, it is assumed that all users will have slowly ramped up their Clenbuterol dosage to eventually reach the listed peak doses.

Sample Clenbuterol cycle #1 (12 weeks total cycle time)
Weeks 1-12:
Testosterone Enanthate at 300mg/week
– Trenbolone Enanthate at 400mg/week
Weeks 1-8:
– Clenbuterol at 120mcg/day
– Ketotifen every second week of Clenbuterol use at 2mg/day

This first listed Clenbuterol cycle example is on the basic end of use, with the general idea in this case of using Ketotifen to maintain Beta-2 receptor up regulation. This would allow the user the to run Clenbuterol consistently for 8 weeks without the need to halt, take a break from Clenbuterol, and then re-initiate use afterwards. Testosterone and Trenbolone are the anabolic steroids of choice in this cycle, where Trenbolone is very notable for its strong nutrient partitioning effects. This would allow further fat loss on cycle.

Sample Clenbuterol cycle #2 (8 weeks total cycle time)
Weeks 1-8:
– Testosterone Propionate at 100mg/week (25mg every other day)
– Trenbolone Acetate at 200mg/week (50mg every other day)
– Anavar at 80mg/day
Clen at 120mcg/day
– Ketotifen every second week of Clenbuterol use at 2mg/day

This sample Clenbuterol cycle #2 includes an oral anabolic steroid into the stack. The oral anabolic steroid in this case is the popular compound Anavar, which is also known for its strong effects on fat loss during a caloric deficit (due in large part to nutrient partitioning). The injectable compounds chosen hold the common trait as a short-estered anabolic steroid, which grant the user the ability to run a shorter cycle which tends to fall in line within the cycling limits of Clenbuterol. This can be compared to Clen cycle example #1 where longer estered compounds are used, and cannot be run in the same time frame as Clenbuterol. Short-estered compounds run in a cycle such as this one are some of the more commonly run cycles due to the precise cutting phases that bodybuilders enjoy running. This is what allows short-estered compounds more compatibility with such a preference.

Sample Clenbuterol cycle #3 (8 weeks total cycle time)
Weeks 1-8:
– Testosterone Propionate at 100mg/week (25mg every other day)
Trenbolone Acetate at 200mg/week (50mg every other day)
– Masteron at 400mg/week (100mg every other day)
– T3 at 90mcg/day
Weeks: 1-2, 5-6, 8+:
– Clenbuterol at 120mcg/day

This sample Clenbuterol cycle should be regarded as an advanced Clenbuterol cycle. This is due primarily to the inclusion of T3. One might be able to notice that the difference between this Clenbuterol cycle and the previous two cycles involves the elimination of Ketotifen. This course of action has been selector for this cycle in order to demonstrate how Clenbuterol can be cycled for a person who does not have access to Ketotifen for whatever reason. If for any reason Ketotifen use is not possible for the purpose of B2 receptor up regulation, then Clenbuterol can be run as displayed above, running it only every two weeks. After a two week period of consistent use, Clenbuterol is then halted for a two week break and then its use re-initiated following this two week break period. It is important to note the distinct mark that Clenbuterol can be run beyond 8 weeks (marked by the 8+ as seen above). This is done to indicate to any individual looking to use Clen that although all other compounds are halted at the 8 week mark, Clenbuterol can indeed continue to be used throughout the PCT period and after the cycle in such a manner. The idea, however, is to ensure that no more than 8 weeks of Clenbuterol total use has not passed. Following an 8 week period of use, it is strongly advised that the user take a prolonged break of several months before resuming Clenbuterol use again.

Clenbuterol Cycle Involving T3 and Other Compounds

As demonstrated in sample Clenbuterol cycle #2, T3 is an additional fat burning agent stacked alongside Clenbuterol. This is a well-known and fairly common practice. It is even a practice that is done without the use of anabolic steroids alongside it, which is not entirely recommended due to the catabolic effects of the T3, but it is nevertheless a regularly engaged practice especially with many female users. Essentially this all depends on each individual’s goals and priorities due to the fact that T3 will often result in considerable muscle loss without the inclusion of anabolic steroids. Females are more apt to engage in T3 use without stacking anabolic steroids with it, and the reason for such a mentality is because most female users are not as concerned with the retention of muscle mass as male users are. The inclusion of T3 and/or T4 into Clenbuterol cycles, especially with anabolic steroids, can elicit a very dramatic thermogenic fat loss effect.

One final additionally stacked compound with Clenbuterol is Human Growth Hormone (HGH). HGH is a hormone well-known for its strong nutrient partitioning effects, and its ability to shift the human body’s metabolism to favor fat as a primary fuel source instead of carbohydrates. HGH, when combined with Clen (and/or T3 as well), is known to create some of the most dramatic fat loss in short periods of time. This is a common and often essential stack of professional bodybuilders, and provided that the individual’s nutrition, diet, and training are all well properly adjusted, much of the same results can be expected.
