Well it appears you will need some product differentiation. Can you comment on your raws testing? Have you considered enhanced characterization more consistent with a pharmaceutical grade product?

Cost implications per vial also in that thread.
Thoughts on being a leader in moving the testing bar for vendors at Meso?
Thank you for your time.
Your HR LCMS is dedicated to gh/peptide testing, correct?
1. So you have indicated your GCMS is set up to screen for AAS side products/androstane raw materials/other assorted organics. Understood. Cost: 170 USD
2. ICP-MS expandable as needed. Cost: 120 USD
3. Residual solvent analysis not available via preferred GC methods since you would need significant investment on the injection system for lower boilers. Got it. Can you provide a little more detail on the moisture analysis? Karl Fischer? Loss on drying? Cost TBD. Need to understand what this...

Good paper detailing structural impurities in the testosterone synthesis step.
You'll see a couple of these were present (very small amounts) in the Pharma product C of A I posted above.
So before someone PMs me again stating the only potential impurities/contaminates in gear are heavy metal impurities, I'll summarize the list:
1. Structural impurities from either API synthesis or coming along with the esterication step (no real health concern above that of AAS API)
2. Heavy metals/elemental impurities
3. Residual...
