What Is Chemyo RAD140?
Chemyo RAD140 is a liquid solution of RAD140 (Testolone) at 10mg/ml in a 50ml bottle, formulated in a PEG400 vehicle. It is consistently one of Chemyo’s highest-reviewed products — currently holding a 4.97 out of 5 rating from 216 verified buyers, with 97% five-star reviews. That rating distribution makes it Chemyo’s top-rated product across their entire catalog.
RAD140, also known as Testolone, is a selective androgen receptor modulator (SARM) developed by Radius Health. It is studied for its exceptionally high anabolic-to-androgenic ratio — approximately 90:1 in preclinical models compared to testosterone’s 1:1 ratio — making it one of the most potent and widely referenced SARMs in androgen receptor selectivity research. RAD140 has progressed through Phase I human clinical trials, including investigations into its potential in androgen receptor-positive breast cancer research.
All products are sold strictly for laboratory and research purposes only. RAD140 is not approved by the FDA for human consumption.

Chemyo RAD140 — Composition and Vehicle
Chemyo RAD140 is formulated in a PEG400 (polyethylene glycol 400) vehicle at 99% PEG400 and 1% RAD140. This is a significant detail that differentiates Chemyo’s RAD140 from many competitors — PEG400 is a pharmaceutical-grade, water-miscible solvent that is the most widely documented vehicle for RAD140 in published research protocols.
PEG400 provides excellent compound solubility for RAD140, maintains chemical stability over the product’s shelf life, and is the vehicle used in peer-reviewed preclinical and Phase I RAD140 studies. Researchers can cross-reference Chemyo’s formulation directly with published literature using this vehicle without needing to adjust for solvent differences.
Full composition disclosure — including the exact vehicle and percentage breakdown — is published on the Chemyo product page. This level of formulation transparency is not universal in the research compound market. Many vendors do not disclose vehicle composition at all, which creates uncertainty for researchers designing protocols that require specific solvent profiles.
Chemyo RAD140 — Quality Control and Testing
FTIR and HPLC dual-method testing
Chemyo RAD140 undergoes two stages of independent third-party testing. The raw RAD140 powder is tested for identity using FTIR (Fourier Transform Infrared Spectroscopy) and for purity using HPLC before manufacturing begins. After the finished 10mg/ml PEG400 solution is produced, it is tested again for concentration using an HPLC assay to confirm the label claim.
The dual-stage testing approach — powder before manufacturing, solution after — catches formulation errors that single-stage testing misses. FTIR confirms compound identity by spectral fingerprint. HPLC confirms purity percentage. The post-production concentration assay confirms the active ingredient is present at exactly 10mg/ml in the finished bottle. All three data points are required before a batch is released.
Batch BA2166 — current COA
The current Chemyo RAD140 batch as of April 2026 is BA2166. Both the FTIR/HPLC identity and purity results and the concentration test results for this batch are publicly downloadable from the Chemyo RAD140 product page — no account, no purchase, and no request required. The COA lot number BA2166 matches the batch code printed on every bottle in the current stock run.
Chemyo publishes two separate test documents per batch: the FTIR and HPLC report confirming compound identity and raw purity, and the concentration test report confirming the finished solution assay result at 10mg/ml. This two-document system is more comprehensive than the single-COA standard used by most research compound vendors.
99%+ purity — what it requires
Achieving consistent 99%+ chromatographic purity on every batch of RAD140 requires more than standard supplier sourcing. Chemyo requires that suppliers perform recrystallization on batches where purity falls below their threshold — a purification process that dissolves and recrystallizes the compound to remove synthesis impurities. Recrystallization reduces supplier yield and is not performed by default unless specifically contracted and paid for. Every Chemyo RAD140 batch to date has tested above 99% purity.
Why compound identity testing matters for RAD140: A 2017 JAMA study found that 48% of products sold as SARMs were either mislabeled, underdosed, or contained no active compound. HPLC purity alone cannot confirm you are receiving RAD140 — it only confirms a compound is present at high purity. FTIR identity confirmation verifies the spectral fingerprint matches RAD140 specifically, ruling out cheaper substitutes. Mass spectrometry cross-checks the molecular weight against RAD140’s known MW of 393.83 g/mol. Chemyo uses FTIR for identity on every batch. Our own store uses mass spectrometry for equivalent identity verification.
Chemyo RAD140 Pricing — Value Analysis
At $79.99 for a single 50ml bottle, Chemyo RAD140 delivers 500mg of RAD140 total. The correct value comparison requires evaluating cost per milligram — not headline bottle price — because the 50ml format is not standard across the market.
| Vendor | Volume | Conc. | Total mg | Price | $/mg |
|---|---|---|---|---|---|
| Chemyo | 50ml | 10mg/ml | 500mg | $79.99 | $0.160 |
| Typical competitor A | 30ml | 10mg/ml | 300mg | $59.99 | $0.200 |
| Typical competitor B | 30ml | 10mg/ml | 300mg | $64.99 | $0.217 |
| Chemyo (3-pack) | 50ml x3 | 10mg/ml | 1,500mg | $71.99/ea | $0.144 |
| Chemyo + crypto (3-pack) | 50ml x3 | 10mg/ml | 1,500mg | ~$64.79/ea | $0.130 |
On a per-milligram basis, Chemyo RAD140 at $0.160/mg is cheaper than competitors selling 30ml bottles at lower headline prices. The 3-pack at $0.144/mg and the crypto+3-pack combination at approximately $0.130/mg represent the best value available in the verified RAD140 market. The 7.95% card surcharge adds approximately $6.40 to a single-bottle card purchase — eCheck and crypto both avoid this surcharge entirely.
Chemyo RAD140 Reviews — What Buyers Report
