The Oxandrolone hormone does not carry any estrogenic related side effects. It does not aromatize and cannot lead to gynecomastia or water retention due to increases in estrogen levels. It further carries no progestin related activity, which again supports no estrogenic related side effects. Due to water retention being impossible with this steroid, this will decrease the risk of high blood pressure. Excess water retention can promote high blood pressure. Some steroids that do not aromatize can lead to high blood pressure, such as Trenbolone , but Anavar is rarely associated with this trait.
Another side effect of the CJC-1295 is acromegaly, since it helps in increasing the levels of the growth hormone. Acromegaly is a condition where extra growth hormone is released even after the internal organs and the skeleton have finished growing. This causes thickening of the skin, deepening of voice, enlargement of jaws, and slurring of speech. Another effect of acromegaly is the swelling of the soft tissue in the internal organs. This could result in the weakening of the muscles of the internal organs, like the heart. This was tested during the phase 2 testing of CJC-1295.
