Winstrol and Tren are anabolic steroids that are used to gain more muscle faster. These substances work in different ways and each has its strengths and weaknesses. I present you my comparison of these two products well known to bodybuilders.
Sommaire
The composition
Stanozolol is the active ingredient in Winstrol. It is a derivative of testosterone that acts like this one to promote the athlete’s muscle development. This substance was used to treat involuntary weight loss following illness or anemia in its early stages. It was only later that weight training enthusiasts began to take advantage of it to optimize the results of their training.

In addition, the active agent in Tren is Trenbolone. Trenbolone was originally a synthetic growth hormone for use in cattle in the Americas. Bodybuilders decided to use the substance to their advantage later when they discovered its effects on muscle development in animals.
Winstrol VS Tren: interesting effects for bodybuilders
The development of muscle mass
The Tren far surpasses the Winstrol in the ability to accelerate weight gain and the ability to optimize muscle volume. Trenbolone improves protein synthesis to promote muscle tissue building.
On the other hand, Stanazololol offers better and longer lasting results compared to Trenbolone by limiting fat accumulation and water retention. These are the reasons why Winstrol would be better suited for experienced bodybuilders who wish to optimize their strength.
Actions during the dry period
The dry period is an important stage after a muscle mass gain, because it is during this phase that the bodybuilder optimizes the results by eliminating fat. He performs specific exercises and follows diets to achieve this goal.
The fat burning effect of Stanozolol is particularly useful during this phase. In addition, this substance limits the deterioration of the muscles thanks to its anti-catabolic effect. Furthermore, the ability of Trenbolone to retain Nitrogen would make it a better ally in preventing muscle wasting and thus loss of volume during this period. Users nevertheless find that Winstrol would be a more interesting option compared to Tren for this phase.
Improved physical performance
The Winstrol and Tren both increase physical performance and endurance. To do this, these substances optimize the production of red blood cells in the blood. This ensures the proper transport of nutrients to the cells as well as better oxygenation of the cells.
In other words, it is possible to choose either of these substances to boost energy. It is thus a solution to increase the duration and/or intensity of training to obtain better results.
The specific effects of Tren
- Tren is an effective ally in helping the body use the nutrients contained in food to promote muscle growth and rapid mass gain. It also gives more strength and endurance ;
- It optimizes the production of the growth hormone IGF-1 which actively participates in muscle development. It also reduces the recovery time after training;
- The product limits the secretion of stress hormones such as catecholamine and cortisol.
Effect specific to Winstrol
Winstrol is a great ally for slimming diets by promoting the elimination of superfluous fat. However, it is necessary to adopt an adapted diet to lose weight.
Winstrol VS Tren: side effects
Androgenic effects
Trenbolone is significantly more androgenic than testosterone. Tren causes pronounced virilization even at very low doses. This results in a change in voice tone, an increase in hair growth, a decrease in breast size or clitoral size.
The inability to naturally produce testosterone when stopped.
On this point, there is no difference between the two substances. This is a common side effect of all anabolic steroids. It is always necessary to restart the treatment when you stop it.

Liver damage
Hepatotoxicity is also an adverse effect common to all anabolic steroids. This leads to various liver disorders such as liver failure or damage. However, Tren is less dangerous if it is given by injection.
Increased levels of bad cholesterol
Winstrol wins the match on the ability to raise bad cholesterol levels in the blood. This leads to clogged arteries and puts you at risk for stroke. However, it should be noted that the dangers are also likely with Tren, especially after high consumption.
Side effects specific to Winstrol
- Joint pain ;
- Psychological disorders.
Side effects specific to Tren
- Baldness ;
Gynecomastia;
Acne;
Insomnia;
Night sweats.
Are these substances legal?
No. Winstrol and Tren are illegal in France and in the European Union countries because of the dangerousness of the side effects. International sports authorities also classify them as doping substances and prohibit their use in competitions. I therefore recommend that you opt for the legal alternatives, which are healthier by the way. These are Winsol and Trenorol, which have received many positive opinions from users.

Winsol and Trenorol
Winsol would be the best alternative to Winstrol, according to users’ opinions. The same goes for Trenorol, which is an effective substitute for Tren. These products manufactured by Crazy Bulk offer virtually the same results as illegal steroids. Their difference? They have no side effects. You can place your order directly on the manufacturer’s website.
