Common questions

What is batch RET-20-C-2604-001?
The current Reta 20mg Pen cartridge. Janoshik Analytical tested it 23 April 2026 at 99.841% HPLC purity and 22.51 mg/mL measured concentration. Task 150762, verification key APSLYZGYW4KA.
How do I verify this Janoshik report independently?
Go to janoshik.com and paste verification key APSLYZGYW4KA. The portal returns the original report off Janoshik's server. Task number is 150762. Neither the report nor the lookup runs through Remy's infrastructure.
What does 99.841% HPLC actually mean?
The report's HPLC method assigned 99.841% of the integrated chromatographic signal to the main peak. That is a method-specific relative-purity result, not a statement that 99.841% of the total sample mass is retatrutide. Identity, assay, residual-solvent, endotoxin, metals and microbial-limit questions require separate evidence.
Which format carries this batch?
The Remy Reta 20mg Pen cartridge. The same batch number applies across that format until a new batch is released, at which point a new record is published here with its own task number and verification key.

For the documented 300-click format, use the separate reta pen clicks-to-mg research calculator to connect listed-material math to this batch record. It is a laboratory-planning reference, not administration or dosing guidance.
