Every published COA entry in this archive is batch-linked to an independent Janoshik Analytical report and reflects a documentation-first testing standard that goes beyond purity alone. The current archive includes the Reta UAE 20mg Pen cartridge batch (RET-20-C-2604-001, 99.841% HPLC), the Reta UAE vial line batch (RET-20-V-2604-001, 99.741% HPLC, with heavy metals, TFA, and endotoxin panels), and the previously published Reta UAE 30mg batch certificate. If you want the plain-English version before reading the PDFs, start with the Peptide COA Guide. Use the lookup below or jump straight into a published batch card.
Purity Leadership
Our highest published batch is RET-20-C-2604-001 — Reta UAE 20mg Pen, 99.841% HPLC, tested by Janoshik Analytical on 23 April 2026. Standard research-grade peptide purity sits in the 95 to 99% range. We are at the top of it. The bigger gap is not the number — it is that we publish heavy metals, TFA, and bacterial endotoxin alongside purity. Most research peptide sellers stop at HPLC. Pharma does not.

HPLC sorts peptide species by retention time on a column. 99.841% is the fraction of the measured peptide that is retatrutide (LY-3437943, CAS 2381089-83-2). The other 0.159% is peptide-related — truncated sequences, synthesis byproducts. HPLC does not see water, salts, or residual solvents, which is why we publish TFA and endotoxin panels separately for the vial line.

RET-20-C-2604-001 — Reta UAE 20mg Pen
Our highest published HPLC purity: 99.841% HPLC, tested 23 April 2026.
Three published batches. Highest is RET-20-C-2604-001 (Reta UAE 20mg Pen) at 99.841% HPLC. The vial line (RET-20-V-2604-001, 10mg and 40mg) is 99.741%. The flagship 30mg Pen (RETP002) is 99.262%. All tested by Janoshik Analytical. Standard research-grade peptide purity sits in the 95–99% range per public references (GenScript, IonPeptide, Proto Peptide).
Who tests Remy retatrutide batches?
Janoshik Analytical. Independent third-party, based in the EU. Every published Remy batch goes through them. Each COA carries a Task number and a verification key you can punch into janoshik.com to pull the raw report off their server. We do not host or edit the report.
What is batch RET-20-C-2604-001?
Current Reta UAE 20mg Pen cartridge. Janoshik tested it 23 April 2026. 99.841% HPLC. 22.51 mg/mL measured concentration. Task 150762, verification key APSLYZGYW4KA.
What is batch RET-20-V-2604-001?
vial line — covers both 10mg and 40mg formats. Janoshik ran a full panel 21–24 April 2026. 99.741% HPLC. 20.92 mg retatrutide assay. Heavy metals (As, Cd, Pb, Hg) not detected. TFA not detected. Bacterial endotoxin 1.449 EU/Vial. Most research peptide sellers stop at HPLC. We publish endotoxin because that is the sterility benchmark pharma uses.
Does Remy test for endotoxin?
Yes. Batch RET-20-V-2604-001 (the vial line) tests at 1.449 EU/Vial via LAL (Limulus Amebocyte Lysate). Endotoxin is the sterility benchmark pharma uses for release testing. Most research peptide sellers skip it. We publish it.
How do I verify a Janoshik COA for a Remy batch?
Every COA we publish has a Janoshik Task number and a verification key. Go to janoshik.com, paste the key, and Janoshik's server shows the original report. Try APSLYZGYW4KA for RET-20-C-2604-001 purity, YCYA75M373NA for the vial line purity, or E8ZFE17MI47D for the endotoxin report. We do not touch the report; you read it off their server.
What does 99.841% HPLC purity mean?
HPLC sorts peptide species by how fast they move through a column. 99.841% is the fraction of the measured peptide that is retatrutide (LY-3437943, CAS 2381089-83-2). The other 0.159% is peptide-related — usually truncated sequences or synthesis byproducts. HPLC does not see water, salts, or residual solvents, which is why we publish TFA and endotoxin panels separately for the vial line.
How does Remy retatrutide purity compare to other research peptides?
Standard research-grade peptide purity sits in the 95–99% HPLC range per public references from GenScript, IonPeptide, and Proto Peptide. Our highest published batch (RET-20-C-2604-001) is 99.841% HPLC, at the top of that range. The bigger gap is documentation: heavy metals, TFA, and endotoxin panels are not standard industry practice. We publish them on the vial line.

Batch RET-20-V-2604-001
Independent Janoshik Analytical reports are published for the Reta UAE vial line (10mg & 40mg) across purity and assay, heavy metals, TFA, and bacterial endotoxin — a sterility-grade test most research peptide sellers never publish.
Endotoxin 1.449 EU/Vial via Janoshik. Most research peptide sellers publish purity only — endotoxin testing is the sterility benchmark used in pharmaceutical release.
