Since it attaches selectively to androgen receptors, it does not carry the sort of side effects that come with anabolic steroids.

Testolone primarily increases lean muscle tissue by enhancing testosterone and human growth hormone as well as boosting other anabolic effects following intense weight training. It may also be able to increase training energy, endurance, and speed while working out.

Testolone is considered to be one of the best SARMs for muscle-building effects but it has also been shown to be effective in fat burning as well.

An initial study conducted on monkeys showed that the administration of Testolone increased their body weight by 10 percent after 28 days of use. Another similar study showed that the negative effects on the prostate and seminal vesicles were significantly reduced by taking Testolone along with synthetic testosterone.

Ostarine is an orally-active, non-steroidal selective androgen receptor modulator (SARM ).

It’s considered to be the best SARM for beginners and it is most commonly used during bulking and recomp phases.

In a 12-week double-blind placebo-controlled phase II clinical trial involving 120 healthy elderly men and postmenopausal women, ostarine was shown to significantly increase muscle issues, and improve physical function and insulin sensitivity. [4]

Ostarine selectively binds itself to proteins within the body that are called androgen receptors. When attached to the androgen protein, it communicates the message for it to get bigger.

Unlike anabolic steroids, Ostarine does not convert to estrogen or DHT. [5]

Ostarine is legal, but only for research purposes. It has not been approved by the US Food & Drug Administration (FDA) and as a result, cannot be sold as a dietary supplement.

Ligandrol LGD-4033 is a selective androgenic receptor modulator (SARM) that was developed by Ligand Pharmaceuticals. It is primarily a mass-building SARM that was originally developed to treat muscle-wasting conditions.

Ligandrol is one of the best SARMs for increasing lean mass and it activates the muscle regeneration process after a workout. This SARM also increases both energy and strength.

Ligandrol can be stacked with a cutting SARM for weight loss in order to preserve muscle size while you are stripping off body fat.

In terms of weight loss, Ligandrol is able to attach to fat receptors and stimulate fat loss. It will boost the metabolism for faster calorie burning.
