Description
The Ligandrol + MK-677 Stack from Pure Rawz puts LGD-4033 and MK-677 together in capsules and tablets. Each batch is checked for 99%+ purity. It’s intended for research use only.
What Ligandrol + MK-677 Stack contains
LGD-4033
LGD-4033 (ligandrol, also coded VK5211) is a nonsteroidal SARM discovered by Ligand Pharmaceuticals and later licensed to Viking Therapeutics. It binds the androgen receptor with high affinity and, in animal models, acts strongly on muscle and bone while sparing the prostate.
Like other SARMs, LGD-4033 binds the androgen receptor and the receptor complex moves into the nucleus to switch on androgen-responsive genes. Its binding is unusually tight, with a reported Ki around 1 nanomolar.
MK-677
MK-677 (ibutamoren) is an orally active, nonpeptide growth hormone secretagogue developed by Merck. It mimics ghrelin at the GHS-R1a receptor, raising growth hormone and IGF-1. It’s often sold next to SARMs, but it isn’t one.
MK-677 binds GHS-R1a, the same receptor as ghrelin and the GHRP peptides, in the pituitary and hypothalamus. That boosts the size of natural GH pulses and lifts IGF-1 from the liver.
Why Ligandrol + MK-677 Stack combines these compounds
Labs pair these compounds because each works through a different pathway, so combining them covers more of the system in one study. A fixed mix also means one product, one label and no drift between separate containers.
Research behind Ligandrol + MK-677 Stack
A phase 1 study by Basaria and colleagues, published in the Journals of Gerontology in 2013, gave LGD-4033 to 76 healthy young men for 21 days. Lean body mass rose with the dose, and the study also reported dose-related drops in HDL cholesterol and testosterone.
Nass and colleagues ran a two-year trial in healthy older adults, published in the Annals of Internal Medicine in 2008. MK-677 raised GH and IGF-1 to levels seen in young adults and increased fat-free mass, with rises in fasting glucose noted.

Options and prices
It comes in 3 options. Pick one from the dropdown above the cart button:
- Capsules, 20mg/60ct/1200mg: $94.88
- Tablets, 20mg/27ct/540mg: $94.88
- Tablets, 20mg/54ct/1080mg: $153.37
The capsules are pre-filled, so each one has the same amount. The size option lists it per capsule.
Tablets are pressed with a fixed amount per tablet, shown in the size option along with the count.
Using Ligandrol + MK-677 Stack in the lab
Labs comparing SARMs usually match exposure time and measure the same panel across compounds: muscle and prostate weight in rodents, plus hormone and lipid markers. That tissue-selectivity ratio is what SARM research is built around.
Liquids make small, even measurements easy, while capsules and tablets suit studies that need a fixed amount per unit.
The classic rodent readout compares levator ani muscle weight with prostate weight, which shows how tissue-selective a compound is. Body composition scans and hormone blood work usually sit alongside it.

How we test each batch
We test each batch for identity and purity before it ships, using HPLC and mass spectrometry, with independent third-party checks on top of our own.
The batch number on the label matches the certificate of analysis. If your lab keeps paperwork on file, ask us for it and we’ll email it over.
How to store Ligandrol + MK-677 Stack
Keep the container sealed at room temperature, away from heat, moisture and sunlight. Write the date you opened or mixed it on the label, so anyone else in the lab knows how old it is.
Safe handling
Wear gloves and eye protection when you open or measure it, and work on a clean surface.
Label everything you prepare, keep it away from food areas, and follow your lab’s rules for disposing of sharps and chemical waste.
Before you start
- nothing extra for capsules or tablets, as each unit is pre-measured
- a dry, sealed container if you split a bottle between projects
