The combination of S4, SR, GW, and RAD makes for a potent lean mass product. RAD is the powerhouse of this blend, delivering strength, size, and density. S4, SR, and GW are the drivers of fat burning; keeping the unwanted body fat off while still being able to pack on strength and mass. If you're looking for a lean, dry, and dense look, Quad Stakk is what you've been searching for.
Directions: take 1 ML twice daily, depending on desired results. For optimal results a 4-12 week cycle is recommended.
S-4, also known as Andarine, Andarin, S-40503, or GTx-007, is a SARM that selectively binds to androgen receptors in skeletal muscle tissue. Due to S4's selective nature, the risk of androgenic activity occurring in non-skeletal muscle tissue is significantly mitigated. Due to its efficacy in producing greater bone density, lean muscle, and strength, andarine is used by the medical community to treat muscle wasting, benign prostatic hypertrophy, and osteoporosis. Additionally, research has shown it does not cause aromatization (conversion of testosterone into estrogen), liver strain, or severe HPTA (hypothalamic pituitary testicular axis) suppression.
Half Life: 4 – 6 hours.
High dosages may result in short-term changes in vision due to a metabolite of S4 binding to vision receptors. Changes go away after the SARM is no longer in the system. Some users have shown very slight suppression when using S4. A short, mini post cycle therapy regiment is required; the recovery time is only 2-3 weeks after completion.
SR9009, also known as Stenabolic, is a SARM that was developed at the Scripps Research Institute. It is a PPAR alpha modifier very similar to GW-501516. It binds to the Rev-erbα protein, which influences lipid and glucose metabolism in the liver and the creation of fat-storing cells.
Stenabolic has been found to increase mitochondria, the powerhouses of your cells. Once mice were given Stenabolic, they were able to run for 50% longer than non-treated mice. It has also been found to aid weight loss.
There are no known side effects, including no known suppression of endogenous testosterone as Stenabolic is non-hormonal.
GW-501516 SARMS, also known as Cardarine, is a PPAR agonist that has been shown to have positive effects on muscle building, endurance, increased HDL (good) and decreased LDL (bad) cholesterol, and body recomposition. Cardarine currently has no human studies, but rodent studies have been very encouraging.
When combined with exercise, GW-501516 combined with four weeks of running increased running time by 68%; running distance by 70%; and doubled overall muscular endurance0. Along with exercise GW-501516 increased mitochondrial growth by 50%. Additionally, GW-501516 on its own has been found to activate many of the genes that activate when an organism goes for a run or exercises.
Cardarine is not hormonal so it is not suppressive of endogenous testosterone.
20 – 24 hours.
The most controversial reported side effect is increased cancer incidence. The one animal study that showed this, out of many studies on Cardarine, used a dose one hundred times larger than the normal dose for over 10 times as long as the research chemical is typically used. This “side effect” is highly disputed. More in-depth studies have found that Cardarine actually reduces tumor size.
Additionally, PPAR agonists have in general been found to have anti-cancer activity.
RAD-140, also known as Testolone, is a selective androgen receptor modulator (SARM) that precisely targets the muscle and bone androgen receptors. Due to its selective nature, RAD-140 minimizes its affects on the liver, kidneys, and prostate. In fact, RAD-140 has the highest ratio of anabolic to androgenic activity of any SARM discovered, 90:1.
None to date, including no effects on liver, kidneys, prostate, nor aromatase conversion (conversion of testosterone into estrogen).
