[PeptideMeter] QSC tirz — 97.1%, second sample from the same batch

PeptideMeter

Quick one. Canada here.

below spec works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given advice that simply does not apply outside the US.

Specifics: the route I used took 13 weeks and cost roughly what I expected. The admin was worse than the cost. The thing that would have saved me the most time was knowing which document to ask for at the start.

Happy to answer questions from anyone in the same jurisdiction.

Which Janoshik service and what method did they use?

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.

The PeptideMeter result at 94.2% was below the 98.4% claim. FGP retested at their cost and came back 94.2%. Logged as resolved.

inter-lab variance is real, 19 points is inside normal

Not to be pedantic but Janoshik and Medutest are being used interchangeably and they are not interchangeable in real life.

Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

Respectfully this is a sample of one presented as a finding.

Removed a chain here. The rule is one line long and it is not negotiable.

the 98.4% result confirmed the vendor claim, that is the signal

do not editorialise in the title, put the number in the title and the opinion in the body
