The muscle stack is one of the best ways to gain muscle fast!


RAD-140 builds muscle and burns fat. With multiple published human trials under its belt, RAD-140 (also called Testolone) is one of the best-studied SARMs. Those studies found powerful results, too. Testolone shows no meaningful side effects and is very effective at building muscle.

Users have said they lost body fat on Testolone (RAD140) and this is due to an increase in metabolism. When you increase lean muscle mass, you also will have an easier time losing body fat.

RAD-140 has greater anabolic effect than testosterone. Elderly men and women who took modest doses of Testolone for 12 weeks grew 3 pounds of muscle and lost a pound of fat, with no changes to diet or exercise. Cancer patients saw nearly identical results along with a similar timeframe. There were no side effects in either study. A pound of muscle a month is about what you would expect with a solid workout routine – but the people taking Testolone in these studies weren’t exercising. Combining the two would be even more powerful, in theory. Pretty impressive!

  •  Increase of Lean Body Mass(LBM)
  •  Decreases fat tissue by increasing muscle
  •  Improvement of Muscle Strength and Physical performance
  •  Improvement of Bone Strength
  •  Treatment of Neurodegenerative diseases
  •  Clinically shown to suppress cancer cell growth by blocking the effects of estrogen on tissues

Ingredients: 2-chloro-4-[(1R,2S)-1-[5-(4-cyanophenyl)-1,3,4-oxadiazol-2-yl]-2-hydroxypropyl]amino-3-methylbenzonitrile,organic MCT oil, natural lemon flavor with stevia.


MK-677 (Ibutamoren) promotes the secretion of the growth hormone(GH) and increases insulin-like growth factor 1(IGF1). It can increase the growth hormone by selective mimicking the hormone Grelin and binding to one of the ghrelin receptors GHSR in the brain. When GHSR has activated, it releases spikes of growth hormone. MK-677 is so great because it increases growth hormone levels but doesn’t increase in other hormones such as cortisol.

Ibutamoren is frequently used to increase lean body mass i.e., create bigger muscles. As previously mentioned, ibutamoren increase growth hormone levels and IGF-1. Both growth hormone and IGF-1, in turn, increase muscle mass, muscle strength, and reduce body fat. In 24 obese men, a two-month treatment (DB-RCT) with Ibutamoren increased lean mass, and transiently increased basal metabolic rate (BMR).

During a study (DB-RCT) in eight food-deprived healthy volunteers, ibutamoren reversed diet-induced protein loss, that could cause muscle wasting. In 123 elderly patients with hip fractures, ibutamoren improved gait speed, muscle strength and reduced the number of falls (RCT).

Growth hormone increases tissue regeneration and wound healing, so ibutamoren may help with these.

  •  Improve exercise endurance and capacity
  •  Improved muscle mass
  •  Improved bone density
  •  Managed body composition
  •  Increased quality of Sleep(REM quality) and sleep duration
  •  Improved quality of Skin, Hair, and Nails 
  •  Transiently increase metabolic rate which results in losing body fat
  •  By increasing IGF-1 it can improve memory and learning
  •  Faster healing of wounds and Tissue Regeneration

Ingredients: R)-1’-(2-methylalanyl-O-benzyl-D-seryl)-1-(methylsulfonyl)-1,2-dihydrospiro[indole-3,4’-piperidine], organic MCT oil, natural lemon flavor with stevia.

    Fast shipping just started them today so we will see by the end how well they work

  3. Corey T. (verified owner)

    I wasn’t positive on what stack I should order so I emailed the company and got some advice. They replied right away and let me know their recommendations. I put my first order in the next day and 7 days later it arrived. I’m very happy with this company. If all goes good I’ll be ordering from them again.

    I’m just into my 3rd week on this stack and so far so good. Theres definitely been some muscle hardening effects, better pumps in the gym and the ability to push a little harder for a little longer. I haven’t noticed any significant strength gains yet but in my experience those come around the 1 month mark. I’ve only rated 4 stars because I don’t care for the “lemon chunks” that are in the compounds. The flavour is alright though.
