Should get better with the addition of volumetric flasks

Jano's testing has margin of error by itself.
3 vial variance of another vendor -- 3rd party tested.

All vials from same batch? How do we know?

Jano has posted RSDs for instrument precision on HPLC (same material injected multiple times) with very low RSD, less than 1% IIRC.

This is all great fun.

They are claimed to be from the same batch. However, the testing was done because of discrepancies around the vendors claims about batches. These samples were supposed to be from a batch that the vendors test results showed a higher concentration. So it is very possible that all three samples did not come from the same batch.

This is RSD example for instrument precision...

Without getting too in the weeds from stats standpoint, @janoshik quotes his HPLC method as 5% margin of error (one sided hence +/- 5?) .

I prefer to stay on the safe side with my claims.

This is why you have both labs report the results of 10 replicates haha. Everyone would be very enlightened by the distribution.

Exciting.

Postscript: would be useful for both labs to share their method RSV (relative standard deviation) based on internal work.

We do multiplicates and I have RSD for this particular sample...

Other part of puzzle is method precision. Haven't seen the raw data presented but under 2% would be excellent (same analyst prepping 10 samples and injecting).

Tren A batch 2 in mig812. Still pending new batch of test c raw results. Jano has them

Stock is low on this, around 150 vials. So if you want it I’d order it sooner than later. Also about 50 left of the MCT batch.

Orders will open 1st January for this. Be sure to specify if you want mig812 or MCT when ordering. Only needed for this batch, until MCT is gone. After MCT gone , all items sold will be mig812

On 1st January we will send finished Test C 250 and Test C 20 to Janoshik, as well as TNE raw. And orders for those will open up whenever results are back. Not selling batch 2 tc250 until batch 3 tc250 results get back. I would like to but, we don’t have enough stock for demand, and would have to close orders a day later.

That is the plan. Only thing that would stop it is test c raw bad test result. Though, I am hopeful it’s going to be good
