Produced by British Dragon, Andropen 275 is a blend of five steroid testosterone with far better results than Sustanon.

Andropen 275 is distributed in 10 ml and 20 ml bottles that contain 20mgs of Testosterone Acetate, 40mgs each of Testosterone Propionate, 75mgs of Testosterone Cypionate, 90mgs of Testosterone Decanoate, and Phenylpropionate.  

Andropen is a combination of five testosterones. The acetate ester allows testosterone to give off an immediate physiological response to an individual. The other four esters, which give off a slower response rate, are responsible for prolonging the initial physiological response.

This product is designed precisely for athletes and bodybuilders, giving steady levels of hormones to the body. Before, some individuals created their testosterone blend out of powders, also a five estered testosterone. Nowadays, it has become common, and some underground labs even create "custom blends" or "house blends" of various estered testosterone.

Technically speaking, testosterone is the cheapest form of anabolic and relatively cheap to produce, so it is always the choice for blended products. It is a "bang for the buck" in terms of results.  



  • Andropen 275 changes both the shape and the size of the muscle fibers; it can transform the appearance and the number of muscle fibers, which is the purpose of cosmetic athletes or bodybuilders.
  • Testosterone can also protect the muscles from catabolic (muscle wasting) glucocorticoid hormones. However, Tren and other more expensive drugs can do much better regarding muscle wasting. The glucocorticoid hormones send messages to the muscle cells to release those stored proteins; on the other hand, testosterone sends a letter to the muscle cells to keep more contractile proteins (also known as actin and myosin). These two are fighting each other. It is a case of anabolic vs. catabolic. The effect is that they are at a stalemate, which is why individuals taking such supplements do not lose weight.
  • Adding testosterone, such as Andropen 275, tips the scale towards anabolism. Erythropoiesis, or red blood cell production in the kidneys, is increased when taking in testosterone, which is highly favorable for athletes. A higher red blood cell (RBC) count in an athlete means more blood carrying oxygen to supply the body, resulting in improved endurance. It can also greatly enhance the body to recover quickly from strenuous physical activity. Aesthetically, it gives the muscles a more "full" look, especially when body fat levels are minimal.
  • An individual may also observe an increase in aggression. The behavior change increases dramatically with exogenous testosterone and is noticeable within the initial day of service.
  • Moreover, great benefits can be achieved using the test alone. However, it is just one part of the cycle for an individual who uses other drug enhancements. People who want to gain muscle and weight will probably choose Deca or Eq (perhaps with Dbol and those who are cutting will probably steer towards Eq and Trenbolone. Users will use this enhancement once or twice a week, with blood levels above baseline roughly eight days after.   Typically, the testosterone portion for such cycle must be equal to or greater than any other injectable drugs portion on an mg basis.

More bodybuilders choose Andropen 275 over Sustanon because of its practicality. Price-wise, Andropen 275 can cost around $150 for a 20ml, multi-use vial, while Sustanon may cost about $50 or more for the same amount of testosterone. Thus, Andropen 275 is still highly recommended when it comes to results. As mentioned earlier, it's a bang for the buck.

Andropen also gives a less watery "bloated look" that testosterone cypionate of an equal amount would produce, but more than one will get with testosterone propionate. This product is more appropriate for bulking or cutting cycles or the ever-popular "lean mass" cycle that is gaining popularity nowadays.  

Side Effects

As expected, there will always be the usual side effect with any testosterone intake.  

For males:
  • Acne,
  • Water retention or edema,
  • Nausea,
  • Excitation or increased aggressiveness,   

Some Unusual Side Effects May Include

  • Sleeplessness,
  • Chills,
  • Vomiting,
  • Hypertension,
  • Bitter or strange taste in the mouth,
  • Change in sex drive,
  • Fatigue,
  • Gum or mouth irritation,
  • Hair loss,
  • Dark urine
  • Light-colored bowel movements

Female May Also Suffer From Side Effects Such As:

  • Menstrual irregularities,
  • Post-menopausal bleeding,
  • Swelling of the breasts,
  • Hoarseness or deepening of the voice,
  • Enlargement of the clitoris, and
  • Water retention

However, The Positive Effects are More Prominent Than The Negative Ones. These Include:

  • Muscle gain,
  • Fat loss,
  • Strength gain, etc.

Again, blends are usually priced high because of their multiple esters. There is a significant price difference when comparing it to single-ester tests. Nevertheless, this product is highly recommended to achieve maximum results.
