EPI is a product which contains 2a,3a-epithio-17a-methyl-5a-androstan-17b-ol, also known as Epistane. It is an active hormone which does not require any conversion, with a structure similar to dihydrotestosterone.


Product Highlights: 

  • It gives rise to muscle mass and strength
  • High anabolic index
  • Increases protein synthesis
  • Accelerates regeneration
  • Improves vascularisation 
  • More anabolic than testosterone
  • Controls estrogens
  • Protects the muscles from breakdown
  • Low androgenic activity
  • High bioavailability

EPI is characterised by an extremely positive relation of anabolic action to androgenic action. The anabolic index is 11 times greater than in the case of testosterone, while the androgenic index remains at a similar level or is even a bit lower. Thanks to this, during the use of EPI we can expect a rapid gain of muscle mass and strength without much worry about typically androgenic side effects, such as hair loss or enlarged prostate.


The anabolic action means forcefully binding of androgen receptors and initiating a significantly faster protein synthesis. The acceleration of biochemical reactions which are responsible for muscle volume results in more effective gain of muscle mass and strength.


The accelerated regeneration during the use of EPI allows for an increase in frequency and intensity of training sessions, which gives us a stronger stimulus to growth.


When using EPI, we do not have to worry about the increase in levels of female hormones. The preparation not only has no tendency to aromatisation but it also shows anti-estrogenic properties! Thanks to it we will not bother with the excessive water retention and the probability of the mammary gland hypertrophy. It also has an influence on more effective fat burning, especially in the resistant areas, because it is very common that estrogens are responsible for any difficulties in this matter.


An interesting effect for any amateur of strength sports will certainly be the ability to maintain the effect of "punched" muscles and significant improvement of vascularisation. Together with the maintenance of the low level of under-skin water, we gain an everyday effect of high quality muscles, just like after the training.


The presence of methyl group in the compound provides high bioavailability by oral dosing, without using needle and syringe.


EPI is a relatively safe compound because of the lack of aromatisation and low androgenic index. The quite universal profile assures its usability regardless of our aim. It will be useful in the period of gaining strength and muscles as well as during reduction. The oral dosing makes it an interesting alternative for classic steroid measures.
