Alternatively boldenone could be stacked with other non-aromatising drugs such as primobolan (methenolone) or masteron (drostanolone) where the small amount of estrogen produced by boldenone is beneficial and the resultant gains should be lean and more easily kept. Given the long undecylenate ester (11 carbons) normally attached to boldenone, injecting the hormone twice a week is more than sufficient, although favourable for stable blood levels over injecting once per week. If one purely wants to use boldenone for its appetite enhancing properties, lower doses of 400mg/week should suffice for this purpose, although the full benefit of boldenone in my opinion is not achieved at these lower doses. Some example cycles are outlined below (I recommend in all cases 500IUs HCG is administered weekly from week 1 throughout the cycle as this will significantly aid recovery by helping to stop shut-down from fully occurring):
Anabolic steroids can cause many adverse effects . Most of these side effects are dose dependent, the most common being elevated blood pressure , especially in those with hypertension ,  and harmful cholesterol levels: some steroids cause an increase in bad cholesterol and a decrease in good cholesterol .  Anabolic steroids such as testosterone also increase the risk of cardiovascular disease ,  or coronary artery disease   in men with high risk of bad cholesterol . Acne is fairly common among anabolic steroid users, mostly due to increases in testosterone stimulating the sebaceous glands .   Conversion of testosterone to dihydrotestosterone (DHT) can accelerate the rate of premature baldness for those who are genetically predisposed.
Like other AAS, boldenone is an agonist of the androgen receptor (AR).  The activity of boldenone is mainly anabolic , with a low androgenic potency. Boldenone will increase nitrogen retention, protein synthesis, increases appetite and stimulates the release of erythropoietin in the kidneys.  Boldenone was synthesized in an attempt to create a long-acting injectable metandienone , for androgen deficiency disorders. Boldenone acts similar to metandienone with fewer adverse androgenic effects.
