What Is RAD140 (Testolone)?

RAD140, commonly known as Testolone, is a research compound classified as a selective androgen receptor modulator (SARM). It was originally developed by Radius Health to investigate potential applications in muscle wasting and breast cancer research. RAD140 selectively binds to androgen receptors in muscle and bone tissue while demonstrating a high anabolic-to-androgenic ratio in preclinical studies.

RAD140 is one of the most potent SARMs studied to date, with a reported anabolic-to-androgenic ratio of approximately 90:1 in preclinical models — significantly higher than testosterone. This selectivity profile has made it a widely referenced compound in androgen receptor research.

All products are sold strictly for laboratory and research purposes only. RAD140 is not approved by the FDA for human consumption.

How Our RAD140 Compares

Frequently Asked Questions — RAD140 (Testolone)

• Is RAD140 legal to buy in the US?

  Yes. RAD140 (Testolone) is legal to purchase in the United States for research purposes. It is not currently a scheduled controlled substance under the DEA Controlled Substances Act. However, the SARMs Control Act has been introduced in Congress on multiple occasions and, if passed, would reclassify SARMs including RAD140 as Schedule III controlled substances.

  RAD140 is not FDA-approved for human consumption, is not legal to sell as a dietary supplement, and cannot be marketed with health or performance claims. It must be purchased strictly for legitimate laboratory or scientific research use. Always verify the current regulatory status in your state before ordering.

• What is RAD140 used for in research?

  RAD140 is studied across several research disciplines due to its potent and selective androgen receptor binding profile. Published and ongoing research covers:

  • Selective androgen receptor modulation and tissue selectivity studies
  • Muscle wasting, sarcopenia, and lean tissue preservation research
  • Bone density and osteoporosis prevention investigations
  • Androgen receptor-positive breast cancer research models
  • Neuroprotection and cognitive function studies in androgen-deficient models
  • Anabolic-to-androgenic ratio comparisons with testosterone and other androgens

  All research use must comply with applicable institutional and regulatory guidelines. RAD140 is not approved for any therapeutic application in humans.

• What is the difference between RAD140 solution and RAD140 powder?

  Both formats contain the same compound — RAD140 (Testolone) — at verified purity. The difference is in preparation and intended application:

  • Solution (10mg/ml in 50ml): Pre-measured liquid ready for immediate use in research protocols. No preparation required. Ideal for consistent dosing studies and standard administration schedules.
  • Powder (1g): Raw compound in lyophilized form. Suited for researchers who need to prepare custom concentrations, formulate capsules, or conduct gravimetric measurement studies.

  Both formats are independently tested and supplied with a batch-specific Certificate of Analysis confirming compound identity and purity percentage.

• How do I verify the purity of your RAD140?

  Every batch of RAD140 we stock has a corresponding Certificate of Analysis (COA) issued by an independent, US-accredited third-party laboratory. We do not use in-house testing or recycle documents across batches.

  Each COA includes:

  • HPLC purity percentage confirming compound concentration
  • Mass spectrometry identity verification matching the correct molecular weight of RAD140
  • Batch lot number that matches the label on the bottle you receive
  • Laboratory name and contact information for independent verification

  COAs are available for download directly on the product page without requiring an account or prior purchase. If your bottle’s lot number does not match the posted COA, contact us immediately for resolution.

• How fast does RAD140 ship and what are the delivery options?

  Orders placed before 2pm EST on business days ship the same day. Orders placed after 2pm EST or on weekends ship the next available business day.

  • Standard shipping: 2–4 business days via USPS or UPS depending on destination
  • Express shipping: 1–2 business days, selectable at checkout
  • Overnight delivery: Available on request for qualifying orders

  All orders are shipped in plain, discreet packaging with no product labeling visible externally. A tracking number is emailed immediately upon dispatch. We ship to all 50 US states. International shipping is not currently available.

• What payment methods are accepted?

  We accept all major payment methods with no hidden fees or processing surcharges:

  • Credit and debit cards: Visa, Mastercard, American Express — zero surcharge
  • Cryptocurrency: Bitcoin, Ethereum, and other major coins accepted
  • eCheck: Bank transfer via eCheck with standard clearing time
  • Zelle and Venmo: Available for domestic US orders

  Unlike the majority of research compound vendors who add 5–10% surcharges to card transactions, we charge no additional fees on any payment method. The price shown at checkout is the final price.

• What is the shelf life and storage requirement for RAD140?

  RAD140 solution and powder maintain stability under correct storage conditions:

  • Solution: Store at room temperature (15–25°C / 59–77°F), away from direct sunlight, heat sources, and humidity. Stable for up to 24 months under correct conditions. Refrigeration is not required and may cause precipitation in the solution.
  • Powder: Store in a cool, dry location away from light and moisture. When kept in a sealed container, powder form typically maintains stability for 24–36 months.

  Each bottle is labeled with a manufacturing date and expiry date. Do not use the compound after the expiry date printed on the label or stated on the COA.

• Can I buy RAD140 in bulk quantities?

  Yes. Bulk and wholesale pricing is available for research institutions, private laboratories, and verified researchers requiring quantities above standard catalog listings. Both solution and powder formats are available for bulk ordering.

  Volume discount tiers are applied automatically at checkout for qualifying order sizes. For institutional purchase orders, custom invoicing, or high-volume requirements, contact us directly via the enquiry form with the following details:

  • Required quantity and preferred format (solution or powder)
  • Intended research application or institutional affiliation
  • Preferred delivery timeline and location

  All bulk orders are subject to the same independent third-party verification standards and include full COA documentation for every batch supplied.
