Are the SARMs you’re using really what they claim to be?
In an industry flooded with underdosed, mislabeled, or outright fake compounds, knowing how to verify SARMs quality is critical—especially for researchers who rely on consistency, purity, and safety.
Here’s your step-by-step checklist to ensure you’re working with legitimate, research-grade SARMs.
✅ Key Takeaways
- Always demand a third-party CoA — if it’s missing, walk away.
- Verify lab credentials — fake CoAs are common; check lab websites and contact details.
- Purity should be ≥98% — anything lower may contain contaminants or inactive fillers.
- HPLC graphs matter — clean single peak = pure compound; multiple peaks = impurities.
- Batch number must match — the CoA should correspond exactly to the product you receive.
- Chemical name & CAS must be correct — errors here are a major red flag.
- Packaging reflects professionalism — look for tamper seals, batch info, and disclaimers.
- Supplier reputation counts — cross-reference feedback from forums and review sites.
- UK-compliant suppliers won’t make medical claims or sell for human use.
- Independent lab testing is the gold standard — consider it if in doubt.
✅ What You’ll Need
- Internet access for lab checks
- Product packaging (or product label info)
- Access to CoA (Certificate of Analysis)
- Basic understanding of HPLC and purity metrics
- 15 minutes and a critical eye
🔟 10 Steps to Verify SARMs Quality
1. Check for a Certificate of Analysis (CoA)
Why it matters: Any reputable supplier will provide a third-party lab report. No CoA? Red flag.
What to do:
- Request the CoA if it’s not public.
- Make sure it’s from a third-party, not the supplier’s in-house lab.
“We only buy SARMs with a fresh, batch-specific CoA — no exceptions.” – UK-based researcher, Reddit/r/sarmsourcetalk

2. Verify the Lab Credentials
Some suppliers fake CoAs with Photoshop. Do a reverse image search or check the lab’s website directly.
Look for:
- Real lab name and address
- Contact information
- Matching test dates and batch numbers

3. Scrutinize the Purity Percentage
Look for ≥98% purity on the CoA. Anything below 95% might indicate low-quality synthesis or contamination.
Bonus tip: HPLC is the most common method; MS/FTIR adds even more credibility.

4. Match the Batch Number on Product & CoA
Batch consistency ensures the CoA actually matches your vial or package.
If the CoA doesn’t match:
- Ask the supplier why.
- It might be from a previous batch (still a red flag).
5. Analyse the HPLC Graph
HPLC should show a single sharp peak. Multiple peaks = multiple compounds = contamination.
Tip: The retention time should match the known RT of that specific SARM (e.g., Ostarine ~4.7min in many labs).

6. Confirm Chemical Name and CAS Number
The CoA should include:
- Correct chemical name (e.g., Enobosarm for Ostarine)
- Correct CAS number (e.g., 841205-47-8)
Mismatch? That’s a serious problem.

7. Inspect Product Packaging & Labelling
GMP-style packaging often signals higher quality standards:
- Tamper-proof seal
- Batch & expiry printed clearly
- Research-use disclaimer
Avoid products with flashy graphics, typos, or vague branding.
8. Cross-Check Supplier Reputation
Search the brand on forums like:
- Reddit (/r/sarmsourcetalk, /r/moreplatesmoredates)
- Trustpilot, Reddit, or YouTube reviews
Look for consistency in customer experiences—not just one-off praise.
9. Verify UK Legal Compliance (if applicable)
In the UK, SARMs must be sold for research use only. Selling for human consumption is prohibited.
Check for:
- “Not for human consumption” disclaimers
- No therapeutic claims on product page
- Transparent, local UK address

10. Test It Yourself (Advanced)
Still unsure? Send the product to a third-party analytical lab yourself
You’ll get:
- Independent confirmation of identity/purity
- Peace of mind for future research batches
🧠 Common Mistakes to Avoid
- Trusting low prices without verification
- Ignoring label discrepancies
- Skipping lab reports “because the site looks legit”
- Not validating who issued the CoA
Legit SARMs or Bust
SARMs can be powerful tools in research — but only when they’re real, pure, and verified. Following this 10-step checklist protects your work, your data, and your integrity.
