LGD 4033 a SARM like Ostarine but 12 times as powerful at only 1/3 the dose! Consequently it is more suppressive to the HPTA (Hypothalamus-Pituitary-Testes-Axis – the system of the hypothalamus, pituitary gland and gonadal glands, which plays a vital role in the development and regulation of the reproductive and immune systems). So, a SERM (selective estrogen receptor modulator) post cycle therapy is recommended.
Where Ostarine is best used in a cutting cycle, LGD has proven itself as a good bulking agent. LGD has a half-life ranging between 24 and 36 hours so daily dosing is optimal.
In a study performed at Boston University, healthy men who were given 1mg of LGD daily gained about 3 pounds in 3 weeks on average. No clinically significant changes were noted in liver function tests, PSA (prostate issue/function tests), hematocrit (testing on the ratio of the volume of red blood cells to the total volume of blood) or ECG (electrocardiogram tests, used to check the heart's rhythm and electrical activity).
However, given the potential for high estrogen side effects while using LGD, it is recommended that you have an AI like Exemestane on hand.
