- Graduated 1 mL glass pipette included for precise measurement.
- Evaporation-resistant formulation and packaging for stable storage.
Why source LGD-4033 from Sports Technology Labs
Quality control across the research-compound industry is inconsistent, which makes third-party verification essential. A 2017 analysis published in JAMA examined 44 products marketed online as SARMs and reported wide gaps between labels and contents.

Verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry.
Suspended in the highest grade carrier and bottled in America.
Prevents BPA leaching and avoids contamination from external tools.
Transparent business, standard payment methods, no misrepresentation.
What is LGD-4033?
LGD-4033 (Ligandrol) is a non-steroidal, orally bioavailable selective androgen receptor modulator (SARM). Mechanistically, it binds the androgen receptor with high affinity and tissue selectivity, distinguishing it from steroidal androgens. It was originally developed by Ligand Pharmaceuticals as an investigational compound (ref. 1).
LGD-4033 remains an experimental research chemical and is supplied strictly for laboratory research. Sports Technology Labs makes no claims regarding its effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals.
Important regulatory information
LGD-4033 is an investigational compound. It is not approved by the FDA and is not a dietary supplement, drug, or food. Marketing it for human ingestion is unlawful.
Listed by the World Anti-Doping Agency under S1 (Anabolic Agents — Selective Androgen Receptor Modulators), banned both in- and out-of-competition (ref. 3).
In the United States, LGD-4033 is not a controlled substance and may be legally purchased and possessed for laboratory research use.
Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
