product description:
american athletes have a long and fond relationship with test c. while testosteron;e enanthate is manufactured widely throughout the world, cypionate seems to be almost exclusively an american item. it is therefore not surprising that american athletes particularly favor this testosteron;e ester.
but many claim this is not just a matter of simple pride, often swearing cypionate to be a superior product, providing a bit more of a "kick" than enanthate. at the same time it is said to produce a slightly higher level of water retention, but not enough for it to be easily discerned.
when we look at the situation objectively, we see these two steroids are really interchangeable, and cypion-ate is not at all superior. both are long acting oil-based injectables, which will keep testosteron;e levels sufficiently elevated for approximately two weeks. enanthate may be slightly better in terms of testostero;ne release, as this ester is one carbon atom lighter than cypion-ate (remember the ester is calculated in the steroids total milligram weight). the difference is so insignificant however that no one can rightly claim it to be noticeable (we are maybe talking a few milligrams per shot). regardless, cypion-ate came to be the most popular testosteron;e ester on the u.s. black market for a very long time.
as with all testosteron;e injectables, one can expect a considerable gain in muscle mass and strength during a cycle. since testosteron;e readliy converts to estrogen, the mass gained from this drug is likely to be accompanied by quite a bit of water retention. the resulting loss of definition of course makes cypionate a very poor choice for dieting or cutting phases.
the excess level of estrogen brought about by this drug can also cause one to develop gynecomastia rather quickly. should one notice an uncomfortable soreness, swelling or lump under the nipple, an ancillary drug like nolvadex should be added immediately. this will minimize the effect of estrogen greatly, making the steroid much more tolerable to use.
the powerful anti-aromatases arimidex, femara, or aromasin are yet a better choice. those who have a known sensitivity to estrogen may find it more beneficial to use ancillary drugs like nolvadex and proviron from the onset of the cycle, in order to prevent estrogen related side effects before they become apparent.
