GP Mast 200 (Masteron)/(Drostanolone Propionate) is perhaps one of the more 'exotic' androgenic / anabolic steroids (AAS) that may be used by an athlete. Originally it was developed and used as an anti-estrogen (under the name Masteril) for the treatment of breast cancer. It was largely used in combination with the SERM (Selective Estrogen Receptor Modulator) Tamoxifen (aka
GP Nolva for the treatment of breast cancer, and did give a significant decrease in estrogen levels in women undergoing such treatment. It is not much used these days for such purposes, for varying reasons, however for many athletes including competitive bodybuilders in particular; Masteron remains a rather unsung favourite of AS medicines.
The fact that Masteron was being used as an anti-estrogen goes to suggest quite a lot about some properties Masteron possesses. GP Mast 200 (Masteron) is a derivative of DHT (dihydrotestosterone) and does not convert to estrogen through means of aromatisation. It is thought that the anti-estrogenic properties of GP Mast 200 (Masteron) may be in part to do with either an inhibition in some way of the aromatase enzyme or an interaction with estrogen itself in a way which blocks receptor binding of the estrogen. Either way, this would put GP Mast 200 (Masteron) as a useful tool for the AS user who uses compounds that convert to estrogen (which most AS users do, considering testosterone is the main basis of most cycles). By inhibiting the aromatase enzyme, GP Mast 200 (Masteron) would be in effect blocking the conversion of free testosterone to estrogen by the aromatisation pathway. This would not only serve to marginally increase the amounts of active free testosterone in circulation (thus giving a greater effect of the testosterone over a Masteron-free system), but it would also negate the side-effects that result from high levels of estrogen due to aromatisation. Such side effects include the development of gynecomastia and water retention/bloating. Conversely, if GP Mast 200 (Masteron) actually blocks the binding of estrogen to the estrogen receptor (ER) in some way, although aromatisation of testosterone may occur, its effects would be limited due to the inability of the estrogen to bind to the ER. Thus through this mechanism, the effects of excess estrogen production through aromatisation would also be limited by use of GP Mast 200 (Masteron).
USAGE:
Due to the effects of Masteron on estrogen related side effects, GP Mast 200 (Masteron) is a very useful tool (especially in competitive bodybuilding) when cutting. As higher levels of estrogen result in water retention, GP Mast 200 (Masteron) inhibits water retention, and many users claim that their muscles feel very full and tight on Masteron, with it giving them amazing 'muscle pumps' in the gym. Use of GP Mast 200 (Masteron)(in combination with other appropriate meds) at low body fat levels results in the user seeing fine detail of the muscles being accentuated, such as striations and the fine details of the muscle. GP Mast 200 (Masteron) helps draw out the water from between the skin and the muscle giving this very cut look (at low body fat levels). Not many other AS medicines can give such effects on muscle detail as those seen with GP Mast 200 (Masteron).
Despite these effects of GP Mast 200 (Masteron), it is a rather weak AS in itself. One would hardly benefit at all from use of GP Mast 200 (Masteron)on its own, and furthermore use of Masteron alone may result in loss of libido due to shutdown of the body's natural testosterone production. For these reasons, it is always recommended to stack GP Mast 200 (Masteron) with other steroids.
It is said by many that using Masteron is a waste when the user has a body fat percentage higher than 10-12%. I can understand the reasoning, and the user must understand that at higher body fat levels the detail to the muscle will not be seen in such a way as described; however I do not see it as a waste due to its anti-estrogenic properties. Such properties may allow one to not use other ancillaries on cycle that would have other undesirable side effects, and in addition GP Mast 200 (Masteron) may work in a synergistic fashion with other AS medicines to amplify their effects (for example with testosterone as described above). GP Mast 200 (Masteron) would however not be recommended for beginner use as it is not needed at this starting out level.
GP Mast 200 (Masteron) can be pretty much incorporated into any cycle containing testosterone. The dosages that should be used with GP Mast 200 (Masteron) are:
- 350-500mg per week (propionate version, injected every other day)
- 400-600mg per week (enanthate version, injected twice per week)
An example of an excellent cutting cycle for an advanced user would be: (6-10 weeks)
- 150mg Testosterone propionate every other day
- 50mg Trenbolone acetate every day (or 100mg every other day)
- 150mg Masteron (propionate) every other day
- 50mg Winstrol every day, last 4 weeks of cycle only
Of course with such an intermediate/advanced cycle, the user could also incorporate other medicines such as GP Clen, Ephedrine, GP T3, HGH, IGF, etc.
A more novice cutting cycle may consist of: (6-8 weeks)
- 100mg Testosterone propionate every other day
- 100mg Masteron (propionate) every other day
SIDE EFFECTS:
The side effects that may occur with use of GP Mast 200 (Masteron) include hair loss (if prone to male pattern baldness), aggression and acne. If a user does experience acne with other androgens such as testosterone, then it is a real possibility that they may experience it with the use of GP Mast 200 (Masteron). I know of people who experience only a few spots with the use of testosterone however when using Masteron they experience many more spots. On the other hand, there are users who seem to experience less spots on GP Mast 200 (Masteron) than they do on Trenbolone.

As with all AAS, it is impossible for anyone to say how an individual will definitely react in terms of side effects, etc with any medicine, as individuals will always differ in their responses to medicines, with differing severities as well. But the user must be aware that the potential is there, and thus take this into consideration when planning a cycle. There are medicines available to combat side effects, such as finasteride for baldness and accutane for acne, however these medicines also have their limitations and must be researched well before use.
