• Yk-11, Rad-140 & Liver Guard

Hardcore Bulk Stack + Support (RAD-140 + YK-11 + Liver Guard)


RAD-140, also known as Testolone, is a SARM, a selective androgen receptor modulator. With this proven peptide there is little danger of nonskeletal muscle tissues experiencing androgen activity. In fact, RAD-140 has the highest ratio of anabolic to androgenic activity of any SARM discovered, 90:1. Serving Size: 2 Caps, Serving per container: 30 Serving,  Amount Per Serving: 30 mg/ml

Half Life:

16 hours.


Studies have used a variety of doses, 0.3, 3 and 30 milligrams daily based on body weight of the research subject. 20-30 milligrams per day is typical, in a cycle of 12 – 14 weeks.

Side Effects

None to date, including no effects on liver, kidneys, prostate, nor aromatase conversion (conversion of testosterone into estrogen).


YK-11 although lumped into the SARM category is actually a myostatin inhibitor. Myostatin inhibits muscle growth. By inhibiting the inhibitor, YK-11 promotes rapid muscle growth. YK-11 has been shown to be more anabolic than dihydrotestosterone (DHT).  

Serving Size: 3 Caps, Serving per container: 30 Serving, Amount Per Serving: 4 mg/ml

Half Life

6 – 10 hours.


3 – 6 mg twice a day in an 8-12 week cycle.

Side Effects

Mild, reversible liver impairment (liver guard suggested). YK-11 has been noted to be suppressive of endogenous testosterone, making a full post-cycle therapy necessary.

Hardcore Liver Guard

Liver Guard is packed with the three most highly recognized liver specific antioxidants in the world. Milk Thistle Extract is the #1 recommended natural herb for liver health, confirmed by hundreds of clinical studies to protect the liver against virtually all types of damage.  N-Acetyl-L-Cysteine (NAC) is a precursor to glutathione, the body’s principal antioxidant that neutralizes free radicals and detoxifies harmful substances. Alpha Lipoic Acid is known as The Super Antioxidant and is both water and fat-soluble and works throughout the body to not just protect but to regenerate other antioxidants.  This triple blend effectively assists in preserving liver cell integrity while neutralizing the occasional harsh elements and negative stress associated with pushing the limits of the human body. Recommended to be used for on-cycle protection as well as off-cycle restoration.
