Storage & handling

Store per standard laboratory practice for liquid research chemicals.

  • Storage conditions: Store in a cool, dry place away from direct sunlight to maximize shelf life.
  • UV-resistant glass bottle with a fixed glass dropper, to limit photodegradation and avoid plasticizer leaching (e.g. BPA).
  • USP-grade PEG-400 base — pharmaceutical-grade solvent carrier for both compounds.
  • Tamper-proof seals, with formulation designed to limit evaporation and hold less than 5% concentration variance.
Sourcing & quality

Why source this stack from Sports Technology Labs

Quality control in the SARM market is notoriously inconsistent. A peer-reviewed analysis published in JAMA examined 44 products sold online as selective androgen receptor modulators and found that labels frequently did not match contents:

52%contained the compound that was actually advertised 39%contained a different unapproved drug not on the label 9%contained no active compound at all

Figures from Van Wagoner et al., JAMA 2017 (ref. 1). Independent third-party verification is essential for reproducible SARM research.

Third-party tested & certified

Both compounds verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry, with batch-linked COAs.

USP-grade PEG-400, bottled in America

Suspended in pharmaceutical-grade PEG-400 and bottled in the USA.

Glass bottles, fixed glass droppers

To prevent plasticizer leaching and cross-contamination from external measuring tools.

60-day money-back guarantee

Transparent business, standard payment methods, no misrepresentation.

Research context

What is in this stack?

This stack pairs two non-steroidal selective androgen receptor modulators (SARMs) — RAD-140 and LGD-4033 — supplied as separate liquid bottles. Both are described below by identity only.

Component 1

RAD-140 (Testolone)

A non-steroidal selective androgen receptor modulator (SARM). Like other SARMs, it binds the androgen receptor. It is used as a research chemical to investigate androgen-receptor pharmacology in experimental models.

Component 2

LGD-4033 (Ligandrol)

A non-steroidal selective androgen receptor modulator (SARM). Like other SARMs, it binds the androgen receptor. It is used as a research chemical to investigate androgen-receptor pharmacology in experimental models.

These compounds are supplied strictly as research chemicals for laboratory research. Sports Technology Labs makes no claims regarding their effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals.

Regulatory & compliance status

Important regulatory information

Not approved for human use

SARMs are investigational compounds awaiting FDA approval. They are not drugs, foods, dietary supplements, or cosmetics, and are not approved for human use. Marketing them for human use is unlawful.

WADA status — RAD-140

RAD-140 is a SARM and is prohibited by the World Anti-Doping Agency at all times under S1 (Anabolic Agents), where SARMs are explicitly named (ref. 4).

WADA status — LGD-4033

LGD-4033 (ligandrol) is a SARM and is prohibited by the World Anti-Doping Agency at all times under S1 (Anabolic Agents); ligandrol is named explicitly (ref. 4).

Our position

Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds, and we discourage SARM use for performance enhancement.
