Selective androgen receptor modulators or SARMs are a novel class of androgen receptor ligands. SARMSoffer the benefits of traditional Anabolics such as testosterone (including increased muscle mass, fat loss, and bone density), all the while, offering a much lower tendency to produce the unwanted side effects. SARMS have very similar overall effects:

  • Increase Testosterone
  • Burn Fat
  • Increase GH
  • Build LEAN muscle
  • ** NO Post Cycle Therapy Required **

SARM's are a breakthrough product in the supplement industry helping you achieve gains never possible before without synthetic products.

This SARM Stack is a combination of 2 of the most popular SARMs available

  • 10mg MK-677
  • 4.5mg LGD-4033

per capsule!

suggested use, take 2 caps per day

LGD 4033 is also known as Ligandrol and Anabolicum. LGD 4033 is among the two most popular SARMs when it comes to bodybuilding, MK-2866 (Ostarine) being the other.

Users claim that LGD-4033 is more potent than MK-2866. Others prefer MK-2866, especially when it comes to cutting cycles. Both are favored for their clean muscle gains, unlike steroids that can cause a long list of side effects and can harm your vital organs.

As all SARMs, LGD 4033 binds to androgen receptors in the muscles and bones with high affinity and selectivity. This means that LGD 4033 shouldn’t affect other organs (sparing the liver, prostate, and sebaceous glands) or cause severe suppression of your natural testosterone production. Being nonsteroidal, LGD 4033 shouldn’t be converted to estrogen either.

How Does LGD 4033 Work?

LGD 4033 raises anabolic activity in the muscles and bones while reducing muscle wasting and bone breakdown. Recent clinical trials attest to the best and safest way to use it to an extent. In clinical trials, LGD 4033 increased lean body mass and strength, decreased body fat, improved wellbeing, and enhanced the healing process. However, the doses and goals of clinical studies differ from its real-world use.

To rewind to the early research phases, both MK-2866 and LGD-4033 were developed with the goal of reducing muscle wasting in people with muscular dystrophy, the elderly, and in cancer patients. Realizing that these drugs may also increase bone strength and healing, scientists began looking into their potential to improve bone diseases such as osteoporosis.

LGD 4033 was initially created by Ligand Pharmaceuticals, hence the name “Ligandrol”.  Viking Therapeutics took over LGD 4033 research in the meantime, renaming it to VK5211. This small pharma company is researching LGD 4033/VK5211 for hip fracture recovery. They state that it will hopefully produce all the benefits of testosterone with improved safety, aiming to get approval for its clinical use sometime in the future.

What is MK677?

Ibutamoren is the term that MK-677 is commonly known as on the market and within the health/fitness industry. The ability of ibutamoren to increase muscle growth is a hot topic.

Misleadingly, Ibutamoren is commonly referred to as a SARM (Selective Androgen Receptor Modulator). SARMs are similar in their chemical structure to anabolic steroids, but without many of the side effects. Ibutamoren, on the other hand, functions by targeting ghrelin receptors which triggers the release of growth hormone through pituitary gland and hypothalamic receptors.

Ibutamoren has been shown to sustain activation of the GH-IGF-1 axis and to increase lean body mass with no change in total fat mass or visceral fat. It is under investigation as a potential treatment for reduced levels of these hormones, such as in children or elderly adults with growth hormone deficiency and human studies have shown it to increase both muscle mass and bine mineral density making it a promising potential therapy for the treatment of frailty in the elderly.

Benefits of sustained consumption of MK677 include:

  • Increase in muscle mass
  • Increase in bone density
  • Increase in appetite
  • Increased fat loss
  • Preventing loss in muscle mass
  • More efficient sleeping pattern
  • Anti-ageing
  • Improved brain function
  • Improved healing & recovery time
