Introduction
Peptides have quickly become one of the most discussed subjects in modern laboratories. These small chains of amino acids are studied for their role in signaling, structure, and cellular processes. But as interest grows, so does the need for clarity and transparency. That’s where Certificates of Analysis (COAs) and quality assurance come in.
At HelloStacks, our mission is simple: to provide research materials with absolute transparency. Every vial, every lot, every detail is backed by documentation. No confusion. No guesswork. Just clear research tools for the innovators shaping tomorrow.
What Are Research Peptides?
Peptides are naturally occurring short chains of amino acids — the building blocks of proteins. In a research setting, they’re studied for:
-
Structure and stability — how amino acid sequences fold and function.
-
Signaling pathways — their role in cellular communication.
-
Experimental applications — how specific peptides interact in controlled laboratory conditions.
In other words, peptides are a cornerstone for countless fields of scientific study.
Why Certificates of Analysis (COAs) Matter
A Certificate of Analysis (COA) is a document that verifies the quality, purity, and identity of a research peptide. It’s not optional — it’s essential. Without a COA, there’s no way to confirm whether a vial meets the standards required for precise research.
A COA typically includes:
-
Purity percentage (e.g., 98–99%)
-
Analytical methods used (HPLC, Mass Spec)
-
Lot number & batch details
-
Molecular weight confirmation
This level of documentation gives researchers confidence in their work, knowing that the foundation of their study is accurate and verifiable.
How to Read a COA
Not all COAs are created equal. Here are three things to check when reviewing one:
-
Purity – A strong COA clearly lists the peptide’s purity percentage.
-
Analytical Techniques – Look for testing methods like High-Performance Liquid Chromatography (HPLC) or Mass Spectrometry.
-
Traceability – Each lot should have a unique number, ensuring that every vial can be tracked back to its batch.
At HelloStacks, every product page links directly to its COA. Transparency isn’t just a value — it’s built into our process.
The Role of Research Stacks
In many cases, researchers don’t study peptides in isolation. Instead, they design “stacks” — groups of complementary peptides arranged for broader experimental insight.
Categories include:
-
Healing & Recovery
-
Cognitive & Nootropic Research
-
Longevity & Anti-Aging
-
Growth Hormone Stimulation
-
Skin & Aesthetic Research
These stacks make it easier to explore relationships between peptides and research outcomes.
