  • SARMS mass stack LGD-4033 and MK-677

    SARMs mass stack

    SARMs mass stack combines 2 of the most effective substances when it comes to increasing muscle mass: LGD-4033 and MK-677

    The first products is LGD-4033 aka Ligandrol and it is one of the most popular and effective SARMs.

    The second products is MK-677 aka Ibutamoren and it is a growth hormone secretagogue.

    LGD 4033 (LIGANDROL)

    LGD 4033 Ligandrol is the most popular of all the SARMS (Selective Androgen Receptor Modulators).  Ligandrol has anabolic effects that are comparable with AAS (Androgenic Anabolic Steroids), but having fewer side effects because of it’s more tissue-selective method of action.

    Ligandrol has been found in World Anti-Doping Agency (WADA) samples and in racehorses too. Like anabolic steroids, it can stimulate muscle growth.

    A quote from the Wikipedia page of Ligandrol:

    SARMs have shown superior side effect profiles compared with anabolic steroids, which arguably makes them attractive for use by individuals seeking an unfair advantage over their competitors


    MK 677 aka Ibutamoren is not a SARM but a growth hormone secretagogue. It works by increasing growth hormone levels as well as IGF-1. Both of these hormones are effective in building muscle, increasing recovery and adding strength.

    The reason why this research compound has gotten popular is because of its ability to enhance growth hormone levels and IGF-1.


    User reports indicate that the optimal dosage is 10 mg/day of LGD-4033 and 25 mg/day of MK-677.
