Read individual product descriptions for a more comprehensive analysis of the respective compounds, but this particular combination works synergistically to add substantial amounts of bodyweight.
 
MK-677 increases IGF-1 production, which substantially increases the body's sensitivity to androgenic activity.
 
LGD-4033, as a selective androgen receptor modulator, is therefore significantly more effective when combined with MK-677.
 
The effect of the LGD-4033 is aided by the effect MK-677 has on ghrelin production. With the corresponding increase in hunger and consumption of additional calories, weight gain is inevitable. 
 
Users can expect this combination to be one of the most potent weight gaining combinations on the market.
