TESTROBIG® SARMs COMBO
TESTROBIG is formulated with three potent SARMs.
LGD-4033 is the most effective kind of SARM for muscle growth. It can increase lean muscle mass while decreasing body fat. It also aids in increasing strength during a workout to make it more difficult.
Conclusions of LGD-4033 Study
Ligandrol, LGD-4033 was safe, had a favorable pharmacokinetic profile, and increased lean body mass even during this short period without change in prostate-specific antigen. Longer randomized trials should evaluate its efficacy in improving physical function and health outcomes in select populations.

MK-677 is a different form of SARM that acts as a growth hormone. MK-677, like any other SARM, is taken orally and does not require an injection like other growth hormones. MK-677 is another fantastic addition to TESTROBIG.
Conclusion of MK-677 Study
Ibutamoren, our results suggest that prolonged administration of MK-677 in rats does not promote growth despite the GH stimulatory effect of MK-677, which may be related to increased expression of SST in the hypothalamus. Further studies are needed to overcome the observed desensitization to GHS.

Testolone, the most recent kind of SARM is RAD-140. The purpose of RAD-140 is to raise testosterone levels in the user without the negative effects associated with steroids. Steroids employ androgen actions to promote muscular development. RAD-140, unlike steroids, stimulates hormone receptors in the body to naturally raise testosterone levels, therefore promoting muscular growth.
