LGD-4033 (Ligandrol, VK5211) has the highest androgen receptor binding affinity of any known non-steroidal SARM at Ki ≈ 1 nM — making documentation integrity non-negotiable. MedChemExpress lists 99.93% purity but locks QC reports behind a contact form and publishes no LAL endotoxin data. Behemothlabz shows COA images on their capsule page without a stated purity figure and without any endotoxin certificate. PureRawz supplies ≥99% HPLC-verified LGD-4033 backed by an independent LAL endotoxin report on every unique lot, shipped from the USA in 1 business day with instant documentation your lab can verify and cite.

Dual Certificate of Analysis
Two independent analytical certifications are issued for every PureRawz LGD-4033 lot — each uniquely tied to your vial's lot number, not a shared batch document.
HPLC Purity Certificate
High-Performance Liquid Chromatography with UV detection is the industry benchmark for quantifying SARM purity. PureRawz HPLC analysis generates a full chromatogram with retention time confirmation and peak purity assessment against certified reference standards — all performed on your specific production lot, not a population representative.
- Purity ≥99% guaranteed on every lot — a minimum floor, not an average
- Full chromatogram retrievable via /verify for your exact lot number — no form submission required
- Compound identity confirmed by retention time against certified LGD-4033 reference
- MedChemExpress: 99.93% listed, but QC report requires a contact form request — no instant public access
LAL Endotoxin Certificate
The Limulus Amebocyte Lysate (LAL) assay is the FDA-recognized standard for detecting bacterial lipopolysaccharide (endotoxin) contamination. HPLC cannot detect endotoxins under any conditions. A compound can achieve 99.93% HPLC purity and still contain nanogram-level LPS that activates TLR4, drives NF-κB nuclear translocation, and floods assay media with IL-6, TNF-α, and IL-1β — completely invalidating AR pathway, anabolic, anti-apoptotic, and bone metabolism research.
- LAL endotoxin result expressed in EU/ml — per-lot report included with every PureRawz order
- Critical for any cell-based AR agonism, caspase, apoptosis, or bone microstructure study
- Suitable for IRB, IACUC, and institutional biosafety committee documentation
- Prevents TLR4-driven false-positive cytokine and inflammatory pathway confounds
Mechanism of Action
LGD-4033 is the highest-affinity non-steroidal SARM characterized to date (AR Ki ≈ 1 nM). Six primary research-documented pharmacological pathways are described below.
Ultra-High Affinity AR Agonism (Ki ≈ 1 nM)
LGD-4033 binds the androgen receptor with a Ki of approximately 1 nM — an order of magnitude more potent than most non-steroidal SARMs including Ostarine (Ki 3.8 nM) and RAD-140 (Ki 7 nM). This exceptional AR affinity translates to anabolic efficacy at very low doses (0.1–1 mg/kg) in preclinical muscle and bone models, making it a primary reference compound for SARM potency benchmark studies.
Selective Muscle and Bone AR Activation
LGD-4033 produces potent agonist activity at the androgen receptor in skeletal muscle and bone tissue while demonstrating reduced androgenic activity in reproductive organs compared to testosterone. This tissue selectivity is mechanistically driven by differential co-activator recruitment at the AR ligand-binding domain upon LGD-4033 versus DHT binding, resulting in distinct nuclear transcriptional programmes.
PI3K/Akt/mTOR Anabolic Signalling
AR activation by LGD-4033 in skeletal myocytes initiates the PI3K → Akt → mTOR axis, driving phosphorylation of S6K1 and inactivation of 4E-BP1 to promote cap-dependent translation of myofibrillar proteins. Additionally, LGD-4033 has been shown to inhibit muscle breakdown by suppressing the ubiquitin-proteasome proteolytic pathway and reducing oxidative stress biomarkers in cisplatin-induced toxicity models.
Bone Tissue Protection and Microstructure
In ovariectomized and orchidectomized rodent models, LGD-4033 has demonstrated dose-dependent improvements in bone mineral density and trabecular microstructure. AR agonism in osteoblasts promotes Runx2 expression, collagen deposition, and bone matrix mineralization, while concurrently modulating OPG/RANKL ratios to suppress osteoclast-mediated resorption — establishing LGD-4033 as a key research model for SARM-mediated osteoporosis intervention studies.
Anti-Apoptotic and Anti-Oxidant Pathways
LGD-4033 AR agonism has been shown to activate anti-apoptotic signalling by upregulating Bcl-2 and downregulating caspase-3 and caspase-9 activation in muscle cell toxicity models. Concurrently, LGD-4033 reduces oxidative stress markers including malondialdehyde (MDA) and reactive oxygen species (ROS), while upregulating antioxidant enzymes including superoxide dismutase (SOD) — effects studied in cisplatin-induced myotoxicity research paradigms.
HPG Axis Dose-Dependent Suppression
In a Phase I clinical pharmacokinetics study, LGD-4033 produced dose-dependent suppression of total testosterone, SHBG, FSH, and LH through hypothalamic-pituitary-gonadal axis negative feedback — effects that were fully reversible following compound discontinuation. This well-characterized HPG suppression profile makes LGD-4033 a reference compound for studying dose-dependent gonadotropin feedback kinetics and reversibility in androgen-dependent endocrine research models.
