Product Details

Human Labs Testo E 500 is a high-concentration injectable testosterone enanthate product. Its declared strength is 500 mg/ml, twice that of a standard 250 mg/ml preparation. Supplied in one 10 ml vial, it differs from the brand’s Testo E 300 mainly in the concentration of the injectable solution.

Testosterone Enanthate

Testosterone enanthate is a long-acting injectable form of testosterone. The enanthate ester allows testosterone to be released gradually after injection, helping maintain hormone levels over an extended period. It is one of the most widely used testosterone esters in bodybuilding and is also used in medically supervised testosterone replacement therapy (TRT).

Use in Bodybuilding

Testosterone enanthate promotes muscle protein synthesis, muscle growth, recovery and strength development. It is most commonly used during bulking phases, when its anabolic effects, combined with demanding resistance training and adequate nutrition, contribute to building muscle mass.

It is also used during cutting phases to help maintain muscle mass and performance in a calorie deficit. Testosterone is not a fat burner, however, and changes in body composition depend primarily on diet, training and overall energy intake.

Combinations with Other Compounds

In bodybuilding, testosterone enanthate is used on its own or as the basis of combinations with other anabolic steroids.

During bulking cycles, it is commonly used alongside nandrolone decanoate (Deca-Durabolin), boldenone (Equipoise) or methandienone (Dianabol), compounds associated in bodybuilding practice with increases in muscle mass and strength.

During cutting phases, combinations with methenolone (Primobolan), drostanolone (Masteron) or oxandrolone (Anavar) are also seen, particularly when the aim is to preserve muscle mass and improve muscular definition.

Possible Side Effects

Testosterone can cause water retention, acne, oily skin, gynecomastia and accelerated hair loss in genetically predisposed men. More serious risks include elevated blood pressure, increased hematocrit and an unfavorable blood lipid profile. Exogenous testosterone also suppresses the body’s natural testosterone production and sperm production, which may adversely affect fertility.
