At TruPeptides, quality isn't a marketing promise—it's a verifiable data point. Every batch of research-grade peptides is synthesized to GMP standards, analyzed by HPLC and mass spectrometry, lyophilized, and shipped cold chain to your door anywhere in Colombia. And all of it is recorded in a Certificate of Analysis you can verify yourself with a QR code.
A research-grade peptide is a compound synthesized and controlled to laboratory standards for use in experimentation—not a medicine. In practice, the difference between a reliable product and one from the gray market comes down to three measurable things: purity (how much of the contents is actually the target molecule), identity (that the molecule is exactly the declared sequence), and stability (that it arrives intact, without degrading from heat or humidity).
TruPeptides was founded precisely to close that gap in Colombia. Every claim we make about a product is backed by a lab data point and by a Certificate of Analysis the customer can verify independently. That's our idea of radical transparency: we don't ask anyone to take it on faith.
From the lab to your hands, every batch goes through the same quality chain. No exceptions, no shortcuts.
Every peptide is synthesized in labs that operate under Good Manufacturing Practices (GMP): raw-material traceability, cross-contamination control, pharmaceutical-grade water, and documentation of every run. The sequence is built amino acid by amino acid through solid-phase peptide synthesis (SPPS).
High-performance liquid chromatography (HPLC) separates the peptide from impurities, salts, and truncated peptides, and quantifies exactly what percentage of the sample is the target molecule. It's the reference technique for measuring purity. Our acceptance threshold is ≥99%: a batch that doesn't reach it isn't released.
Mass spectrometry (MS) measures the compound's exact molecular weight and confirms that the molecule matches the declared sequence. HPLC answers "how pure is it?"; MS answers "is it really this molecule?". Only when both tests pass do we certify identity and purity.
The peptide is lyophilized—vacuum freeze-dried—to remove the water and stabilize the powder, extending its shelf life. It's packaged in a sterile vial under controlled conditions, and the Certificate of Analysis (COA) that accompanies that specific batch is issued, with its unique number and its verification QR code.
Peptides are sensitive to heat, light, and humidity. That's why every order ships holding a temperature of 2–8 °C with gel packs and insulated packaging, and is delivered across Colombia in 24 to 48 hours by trusted couriers (Coordinadora / Servientrega), with tracking all the way to delivery.
They're complementary techniques. One measures purity; the other, identity. Together they certify that the vial you receive is what it claims to be.
High-performance liquid chromatography passes the sample through a column that separates its components. Each compound appears as a peak on the chromatogram; the area of the main peak indicates the purity percentage of the target peptide.
Mass spectrometry ionizes the molecule and measures its mass-to-charge ratio with extremely high precision. By comparing the measured molecular weight against the theoretical weight of the sequence, it confirms that the compound is exactly the declared peptide, and no other.
Every TruPeptides vial arrives with a batch Certificate of Analysis. It's not decoration—it's the evidence that the product passed the checks. Here's how to read it, point by point.
Certificate of Analysis
Certificate of Analysis (COA) · Illustrative sample document
The QR links to the batch's digital report: purity, identity, and date, signed by the lab.
Uniquely identifies the production run of your vial. It's the key that connects the powder in your hand with its lab report. No batch number, no traceability.
The percentage of the contents that corresponds to the target peptide. Always look for a value of ≥99%. If a seller doesn't report HPLC purity, they can't prove what's really inside the vial.
"Confirmed" means mass spectrometry verified the molecular weight and that the molecule is the declared sequence. It's the proof that you're not being sold a different compound.
Shows which techniques were used (HPLC-UV and LC-MS) and when the batch was analyzed. A recent date supports the stability of the lyophilized compound.
Scanning it takes you to the batch's digital report. It's what turns a label into independently verifiable proof: the essence of our radical transparency.
The values shown on the card are an illustrative example. The real COA for each batch is generated from its own lab analyses.
Full guide: how to verify purityThese aren't slogans—they're the rules we apply to everything we sell.
Production under Good Manufacturing Practices, with documented traceability of every raw material and every run.
A fixed release threshold. A batch that doesn't reach 99% purity doesn't ship, no exceptions.
Every batch is confirmed by mass spectrometry: the molecule you buy is exactly the one declared.
A Certificate of Analysis independently verifiable on every vial. No blind faith.
Freeze-drying for maximum stability and a shelf life of up to 24 months under refrigeration.
Refrigerated shipping with gel packs and insulated packaging, delivered in 24–48 h to major cities.
HPLC purity indicates what percentage of the sample corresponds to the target peptide, separating it from impurities, salts, and truncated peptides. A purity of ≥99% means less than 1% of the contents are byproducts. In research this is decisive: impurities above that threshold can alter results and compromise the reproducibility of an experiment. That's why we set 99% as the minimum release threshold.
They're complementary techniques. HPLC (high-performance liquid chromatography) measures how pure the peptide is. Mass spectrometry (MS) measures its exact molecular weight and confirms its identity—that is, that the molecule really is the declared sequence. HPLC answers "how pure?" and MS answers "is it really this molecule?". TruPeptides applies both to every batch before issuing the Certificate of Analysis.
Every TruPeptides vial includes a Certificate of Analysis with a unique batch QR code. Scanning it opens the report showing the batch number, the purity measured by HPLC, the identity confirmation by mass spectrometry, and the analysis date. This lets you independently confirm that the product you received matches the declared molecule and purity, without relying on our word alone.
Lyophilization (freeze-drying) removes the water from the peptide and stabilizes it as a powder, extending its shelf life for up to 24 months. Even so, peptides are molecules sensitive to heat, light, and humidity, so they're kept refrigerated at 2–8 °C, protected from light. That's why we ship with gel packs and insulated packaging: the cold chain protects the compound's integrity from the lab to your door. Reconstitution is done with bacteriostatic water, which is not included in the vial.
