The Four-Stage Testing Pipeline

Every product goes through four independent verification stages before it is released for sale. Not one. Not two. All four — documented and publicly available against your batch code.

Three Independent Tests. Every Single Batch.

We use the three most rigorous analytical methods available for research chemical verification. Here is exactly what each one tests and why it matters for your research.

Frequently Asked Quality Control Questions

Everything you need to know about how we test, verify, and document every product we sell.

• Why do you test powders for identity and purity? +
  Simply put, without testing a compound it is impossible to be 100% certain that it is exactly what it claims to be. While we have absolute confidence in our suppliers, it is important to us to independently verify every powder for correct identity and highest purity. This is only possible through appropriate analytical techniques.
  
  To accurately identify our compounds, we send them to a third-party lab that uses FTIR (Fourier-Transform Infrared Spectroscopy). FTIR generates a complex spectrum report of peaks and valleys that confirms the compound’s exact molecular composition.
  
  To establish purity, our third-party lab uses HPLC (High-Performance Liquid Chromatography). Without this test, compounds may contain impurities that affect your end result. Doing these tests on all raw powders is part of why we have absolute confidence in the final product we deliver to our customers.
• Why do you test your solutions for potency? +
  Thanks to our raw powder testing, we already know that our compounds are of the correct identity and high purity when they enter manufacturing. Our solutions are produced in a professional clean contract manufacturing facility by trained personnel using appropriate equipment.
  
  However, there is always a small risk of human error or equipment malfunction during the manufacturing process — even in the best facilities. To verify that our finished solutions match our label criteria, our third-party lab performs an assay using HPLC on every batch of finished product.
  
  By testing for potency, we can be certain that our customers receive solutions that are not underdosed and that match exactly what is stated on the label. This is the test most suppliers skip. We do not.
• How is it possible that all your raw powder testing data shows over 99% purity? +
  When our suppliers synthesize a compound, it will have a specific purity level after synthesis. It is possible to increase purity further by applying a technique called recrystallization — a purification method used to remove residual impurities after initial synthesis.
  
  Typically, suppliers will not apply recrystallization unless specifically requested, because the yield of their synthesis decreases and cuts into their margins. Our suppliers know that we hold extremely high standards. When required, they recrystallize batches specifically for us so that we can provide our customers with compounds that have less impurities.
  
  To date, all our testing data, across all raw compounds, shows a chromatographic purity exceeding 99%.
• Where are your solutions manufactured? +
  Our solutions are manufactured in a modern, professional, clean contract manufacturing facility. Manufacturing is performed by trained personnel using appropriate laboratory equipment. The facility operates under documented quality control procedures and our solutions are tested by our third-party logistics provider before fulfilment.
• Why does my concentration test report show a result marginally above or below the label? +
  It is important to understand the difference between testing the purity of raw powders and testing the concentration of the finished solution.
  
  The concentration assay test measures the active ingredient in the finished solution by comparing it against solutions made from pure, reference materials. Due to the nature of this measurement, there can be random errors in weighing, volumes, injections, and peak integration. As a result, the precision of a single measurement has an assumed variance of ±10%.
  
  A result marginally above or below your label criteria (for example, 25.3mg/ml on a 25mg/ml product) is within normal analytical precision and does not indicate a quality issue. The result confirms the solution is correctly dosed and within acceptable tolerance.
• What is batch coding and why is it important? +
  Batch coding is the system through which we assign a unique identifier to every production batch. This unique code appears on the label of every product you receive and is used to:

  • Track and trace products throughout our supply chain
  • Identify affected products in the event of a quality issue
  • Allow customers to look up the specific lab report that belongs to their exact batch

  You can find the batch code on the label of your bottle or vial and use it to access the corresponding COA on our lab reports page. This ensures the report you are viewing corresponds exactly to the product you received.
• What does “our supply chain guarantees quality” mean? +
  Our quality guarantee is not based on trust alone — it is based on documented, independent third-party verification at every step:

  • Raw powders are tested by our third-party laboratory before entering the manufacturing facility
  • Finished solutions are tested by our third-party logistics provider before being despatched to customers
  • Every product manufactured and every product shipped is documented by independent third parties

  This means you can be absolutely certain that what has been tested is exactly what you receive. The chain of custody is unbroken and independently verified at each stage. There is no gap between the tested product and the shipped product.

What a Batch COA Looks Like

Every batch COA contains full raw third-party test data — not just a summary. Here is a representative example of the documentation available for every product.

Your Batch Code — How to Use It

Every product you receive from chemyo.cc carries a unique batch code printed on the label. Use it to pull up the exact lab report for your specific production lot.

Documented at Every Stage

Our quality guarantee is independently documented at each step. What has been tested is provably what you receive.
