Increasing endurance is not always an easy task if we try to do it with anabolic steroids. Most often, athletes use drugs such as erythropoietin to increase it, as well as drugs that dilate blood vessels and increase oxygen delivery to the blood. The format of our article is still more devoted to anabolic drugs, so we will not dwell in detail on the means of increasing endurance, but still try to talk a little about the role in increasing productivity in relation to anabolic steroids.

The problem with endurance and anabolic steroids is that, firstly, large doses of steroids actively build muscle mass, which means additional energy losses for cyclical sports athletes, because working with muscles is a very energy-intensive work. Secondly, increasing your own weight also reduces endurance, because you have to spend more calories on each movement than before. In addition, the more muscles there are, the faster they acidify during work, which is extremely limiting for an athlete. That is why dosages should be minimal, and the duration of the cycle is not very long.

HOW STEROIDS WORK

The mechanisms by which anabolic steroids can increase endurance include increased production of red blood cells, which improves oxygen transport to tissues. Increasing the level of hemoglobin in the blood allows the muscles to receive more oxygen, which is important for aerobic exercise. Steroids can also accelerate recovery after exertion, reducing damage to muscle fibers and reducing inflammation.

The endurance associated with anabolic steroids is associated with an increase in the number of red blood cells (red blood cells). In general, this increases the oxygen supply to the muscles, which is extremely important for aerobic activity. Without exception, androgenic anabolic steroids increase the number of red blood cells, but there are also those that increase it to a greater extent - these are nandrolone, as well as boldenone, oxymetholone and testosterone.

Another nuance of anabolic steroids and endurance is that the hematocrit level, which is useful for increasing endurance, has strictly defined limits that cannot be exceeded, but they are very invasive. For example, if you are engaged in cycling and your hematocrit has increased from 45% when using steroids to 50%, then most likely you will get some benefit from increasing it, but if you increase the dosage and your hematocrit is 58%, then most likely your endurance will deteriorate. This balance must be observed, and you can only determine the exact level of hematocrit at which your endurance increases by personal experiment.

In conclusion, we would like to conclude that the use of anabolic steroids to increase endurance is not always the most effective option, but despite this, some athletes integrate anabolic steroids into their endurance training, although in a very specific way that differs significantly from the use of anabolic steroids to increase strength or increase muscle mass, at least in dosages.

WHOM IS IT SUITABLE FOR

In fact, it seems that anabolic steroids are not very suitable for increasing endurance, which is aimed at very long loads such as a marathon or for cyclic sports, but can be effectively used in sports where both endurance and strength are needed, for example in martial arts or rugby. In this case, anabolic steroids will not be used to increase endurance, but rather to increase strength and strengthen bone tissue, tendons and muscles, but the doses should be selected in such a way as to avoid a significant decrease in endurance.

In this case, the use of steroids can be considered justified and the real reason for their use will sound like an overall increase in productivity and efficiency due to increased strength and compaction of tissues involved in a particular type of activity. It may not make you a more resilient fighter in the ring, but your punches will be heavier and your opponent will get tired of it faster than usual. Of course, this could lead to the conclusion that the scheme for increasing strength (bulk) would be more effective if you just wanted to increase the force of impact, and this would be true, but it is very important for us not to lose endurance and that is why we cannot use such large dosages as well as use such drugs that will significantly retain water in the body, although in terms of increasing the impact force, this would be the most effective option.

It is also worth considering another factor that can have a positive effect on increasing productivity for both fighters and athletes of other sports - this is an increase in aggression. Despite the fact that this is a rather subjective effect that can manifest itself in some athletes and is completely absent from others, it is impossible to deny the stimulating effect of anabolic steroids on the central nervous system because it is present, but to varying degrees. Steroids with a high degree of androgenicity, such as Halos (fluoxymasterone), Superdrolyn or trenbolone, are usually recommended to increase aggression. Some fighters use these drugs before fights in order to be able to more effectively tolerate the discomfort inflicted by an opponent and go forward with clenched teeth.

If you still decide to try using anabolic steroids to experiment and test their effectiveness on your own experience for your endurance, then we recommend using minimal dosages. Also, below we will give examples of some other PEDs that can increase your performance in terms of endurance.

Testosterone

If you use testosterone - the dosage should be minimal, perhaps 125-200 mg. You should make sure that you do not gain weight due to fluid retention in the body - this will significantly interfere with your workouts and worsen the results. A higher dosage is more likely to delay too much liquid.

SARMs and steroids without testo base

There is an exception in the cycle to increase endurance and performance - you can do without testosterone when using anabolic steroids or SARMs if the cycle duration is short - 4-6 weeks. Considering that your doses will be minimal (and these are exactly the doses that you need), then such a scheme is acceptable. Also, to increase endurance, you can generally do without any anabolic steroids and can use only those drugs that will directly affect endurance - for example, clenbuterol and SR9009 and others, as well as their combinations.

Usually, one or more other anabolic steroids are added to testosterone during an endurance cycle. It is important that any medications you take do not cause water retention. To do this, it is important to control the estradiol index, as well as combine those drugs that do not aromatize. Stanozolol - can be used to improve recovery. Drostanolone - due to its properties, it can give a derivative of dihydrotestosterone to improve recovery. Provironus, Primоs (oral and injectable), S4, Ostarin, RAD140 and Anavaros - does not cause fluid retention and therefore can be used.

OTHER PEDS

Below we will look at some other means that can in one way or another affect the functional state of your body and consequently improve your endurance, speed up recovery after training and make your body more prepared.

SR9009

SR9009, commonly known as Stenabolic, is a synthetic Rev-Erb ligand that has gained attention for its potential to enhance endurance and overall physical performance. By activating the Rev-Erb protein, SR9009 influences the regulation of the body's internal clock and metabolic processes. This leads to increased mitochondrial activity and enhanced energy production in muscle cells. As a result, athletes and fitness enthusiasts may experience significant improvements in stamina, allowing them to train harder and longer without fatigue.

Moreover, SR9009 enhances glucose and lipid metabolism, promoting efficient energy utilization and fat burning. This dual action not only helps in reducing body fat but also provides a continuous energy supply during prolonged physical activity. Additionally, SR9009 has been shown to reduce inflammation and oxidative stress in muscle tissues, further supporting endurance and recovery. By improving mitochondrial function, optimizing energy expenditure, and reducing muscle fatigue, SR9009 stands out as a promising agent for those looking to boost their endurance and overall athletic performance.

However, it is important to note that the oral bioavailability of SR9009 is limited, that is, when taken orally, the active substance is not fully absorbed by the body. This may limit its effectiveness compared to other methods of administration.

Clenbuterol 

Clenbuterol, initially developed for treating asthma, is a potent bronchodilator that widens the airways and eases breathing. This ability to increase lung capacity and improve respiration makes it popular among athletes and bodybuilders aiming to boost their endurance and overall performance. Clenbuterol acts as a beta-2 agonist, stimulating the central nervous system and leading to increased production of catecholamines such as adrenaline. This elevates heart rate, accelerates metabolism, and enhances oxygen delivery to muscles, which is crucial for endurance training and competitions.

Additionally, clenbuterol promotes lipolysis—the breakdown of fat cells for energy. This helps athletes reduce body fat and improve body composition, which is vital for achieving high endurance. Clenbuterol also possesses anabolic properties that contribute to increased muscle mass and strength. Thus, clenbuterol not only enhances respiratory functions and energy metabolism but also supports muscle performance, making it an effective agent for boosting endurance and athletic performance.

Yohimbine

Yohimbine, an alkaloid derived from the bark of the yohimbe tree (Pausinystalia yohimbe), is initially known for its ability to improve erectile function and increase libido. However, its effects on the body can also contribute to enhancing physical endurance. Yohimbine acts as an antagonist of alpha-2 adrenergic receptors, leading to increased levels of norepinephrine in the body. This, in turn, heightens sympathetic activity, increasing blood flow to the muscles and improving their oxygenation. 

Due to these effects, yohimbine can help boost energy levels and endurance during physical exertion.

Additionally, yohimbine promotes lipolysis—the breakdown of fats in the body, making it popular among athletes and those looking to reduce body fat. The increase in norepinephrine levels and activation of the sympathetic nervous system stimulate the body to utilize fat stores as an energy source, which is particularly beneficial during intense workouts and competitions. Thus, yohimbine not only enhances physical endurance by raising energy levels but also aids in the more efficient use of the body's energy resources.

Telmisartan as an Endurance-Enhancing Agent

Telmisartan, primarily known as an angiotensin II receptor blocker (ARB) used for treating high blood pressure, has gained interest for its potential to enhance endurance and athletic performance. It acts by blocking the effects of angiotensin II, a hormone that constricts blood vessels, thereby improving blood flow and reducing cardiovascular strain. This increased blood flow ensures a more efficient delivery of oxygen and nutrients to muscle tissues during exercise, which can enhance endurance and delay the onset of fatigue.

Furthermore, telmisartan has been shown to activate the peroxisome proliferator-activated receptor delta (PPAR-delta), a key regulator of energy metabolism. Activation of PPAR-delta increases the oxidation of fatty acids, which helps in using fat as a primary energy source during prolonged physical activity. This not only improves endurance but also aids in better body composition by reducing fat stores.

For endurance enhancement, the typical dosage of telmisartan ranges from 20 to 80 mg per day, with 40 mg being a commonly recommended starting dose. It is advisable to start at the lower end of the dosage range to assess tolerance and then adjust as needed. Telmisartan should be taken once daily, preferably at the same time each day, to maintain stable blood levels. As with any supplement or medication, it is essential to consult with a healthcare provider before starting telmisartan for endurance purposes to ensure it is appropriate for individual health conditions and to monitor for potential side effects.

Somatropin

Growth hormone (GH), also known as human growth hormone (HGH), is naturally produced by the pituitary gland and plays a crucial role in growth, metabolism, and muscle development. It has gained popularity in the athletic community due to its potential to enhance overall physical performance. GH promotes muscle growth, increases protein synthesis, and accelerates the recovery of muscle tissues, which can contribute to improved endurance and reduced recovery times after intense physical activities. It also acts as an anti-catabolic agent for muscles under conditions of calorie deficit and stress. Additionally, GH enhances the utilization of fats as an energy source, helping to sustain prolonged physical activity by preserving glycogen stores.

Another key benefit of GH is its ability to increase the production of insulin-like growth factor 1 (IGF-1), which plays a significant role in muscle repair and regeneration. This can lead to increased muscle explosive strength, allowing athletes to train harder and longer. Moreover, GH's ability to stimulate collagen synthesis can improve joint and tendon health, reducing the risk of injuries and ensuring more stable training sessions.

When using growth hormone, the typical dose for endurance sports and combat sports ranges from 2 to 4 IU (International Units) per day. It is recommended to start at the lower end of the dosage range, such as 1-2 IU per day, to assess individual tolerance and minimize possible side effects like fluid retention. The dosage can then be gradually increased to the desired level. GH is usually administered via subcutaneous injection, and it is best to split the daily dose into two injections, one in the morning and one in the evening.

If GH causes excessive fluid retention, it may negatively impact your endurance. Moderating carbohydrate and sodium intake in your diet can often help reduce fluid retention. It is worth mentioning that there are no studies confirming that GH enhances endurance in athletes, but there is personal practice among many endurance athletes who, despite this, actively use it and consider it effective for their goals.

Glutathione

Glutathione is a powerful antioxidant that plays a key role in protecting the body's cells from oxidative stress. It is composed of three amino acids: glutamine, cysteine, and glycine. For athletes looking to improve their endurance, glutathione can be an important addition to their training regimen and nutrition. During intense physical activity, the production of free radicals increases, which can damage cells and tissues. Glutathione helps neutralize these harmful molecules, thereby protecting muscles and other tissues from damage. This allows athletes to recover faster and reduce feelings of fatigue.

Additionally, glutathione plays an important role in maintaining immune system function, which is especially crucial for athletes subjected to intense training and stress. A decrease in glutathione levels can lead to reduced immunity, increasing the risk of illnesses and infections. Maintaining adequate glutathione levels supports overall health and well-being, which in turn positively affects endurance. Some studies also suggest that glutathione supplementation can enhance aerobic endurance and improve the body's ability to utilize oxygen, which is a key factor in boosting athletic performance.

Modafinil

Modafinil is a nootropic drug originally developed for the treatment of narcolepsy and other disorders associated with excessive daytime sleepiness. However, in recent years, it has gained recognition as a substance capable of enhancing cognitive functions and physical endurance. Modafinil affects the central nervous system by increasing dopamine levels in the brain, which helps improve attention, concentration, and wakefulness. This can be beneficial for athletes, as it allows them to maintain a high level of activity and focus for longer periods, especially during long competitions or intense training sessions.

In addition to improving cognitive abilities, modafinil can also indirectly enhance physical endurance. It reduces the feeling of fatigue and perceived exertion, allowing athletes to perform physical exercises for longer without experiencing significant tiredness. Some studies suggest that modafinil can improve aerobic endurance, especially under conditions of sleep deprivation or stress. Modafinil should be used immediately before training or competition.
