Quality & Testing

Trust is a document, not a slogan.

Anyone can print "high purity" on a label. We'd rather show you the paperwork. Here's exactly how every Dissolv batch is tested, what a Certificate of Analysis actually says, and how to get the one for your lot.

The process

Four checks before a batch ships

Every lot goes through the same sequence. If a batch fails any step, it doesn't get sold — it gets rejected.

01

Identity

The question: is this actually the compound on the label?

Mass spectrometry confirms the molecular weight matches the expected structure. This is the check that catches the single biggest problem in this industry — vials that simply contain something else.

02

Purity

The question: how much of the vial is the real thing?

HPLC (high-performance liquid chromatography) separates the sample into its parts and measures each one. Our release threshold is ≥99% or higher. The remainder is typically residual solvents and related peptide fragments.

03

Content & fill

The question: is the stated amount really in the vial?

Quantitative analysis verifies the labeled mass. A vial marked 10mg should contain 10mg — under-filling is common in this category and rarely disclosed.

04

Batch release

The question: can we prove all of the above, later?

Results are tied to a specific lot number and archived. That's what makes a COA meaningful — it's traceable to the exact batch in your hand, not a generic sample from last year.

Plain English

How to read a Certificate of Analysis

COAs look intimidating on purpose. They're not. Here's every line that matters, translated.

Lot / Batch Number
The batch fingerprint. This is the most important line. If it doesn't match the number on your vial, the COA is for someone else's product. A supplier who sends the same COA to everyone is telling you something.
HPLC Purity
What percentage of the contents is the actual compound. Look for a number and a chromatogram — the squiggly graph. One tall peak is good. Several significant peaks means several substances.
Mass Spec / MS
Confirms identity. The measured molecular weight should closely match the theoretical weight printed next to it. If those two numbers disagree, the compound isn't what the label claims.
Appearance
Usually "white to off-white lyophilized powder." Lyophilized just means freeze-dried. Discoloration or clumping in the actual vial is a reason to stop and contact us.
Test Date & Testing Facility
When it was tested and by whom. A COA with no date, or no named lab, is decoration rather than evidence.
Water Content / Residual Solvent
Leftovers from manufacturing. Small numbers are normal and expected — this is a completeness check, not a red flag.
The three-second version: match the lot number, check purity is at or above ≥99%, confirm the mass-spec numbers agree. Everything else is supporting detail.
Handling

Storage & cold chain

Purity at the lab means nothing if the material degrades in transit. Two things protect it.

How we ship

Orders leave the same business day in insulated packaging with ice packs. Lyophilized peptides are relatively stable in transit, so arriving at room temperature is not cause for alarm — the cold chain is a margin of safety, not a pass/fail test.

On arrival

Lyophilized material is typically stored refrigerated or frozen, protected from light, in its sealed vial. Storage guidance for a specific compound belongs with the researcher's own protocol — we supply the material and its documentation, not handling instructions.

Questions

Straight answers

How do I get the COA for my order?

Email aloha@dissolvlabs.com with your order number or the lot number printed on the vial, and we'll send the batch-specific certificate. We don't gate it behind a form or a purchase.

What does "Research Use Only" actually mean?

It means these materials are supplied for laboratory research. They are not medicines, not supplements, and not for human or veterinary consumption. They haven't been evaluated by the FDA for safety or effectiveness in people. This isn't fine print we're hiding — it's the entire basis on which the products are sold.

Who does your testing?

Analysis is performed by independent third-party laboratories, not in-house. That independence is the point: a purity number is only as trustworthy as the distance between the person selling the product and the person measuring it. The testing facility is named on each COA.

Is every single batch tested, or just some?

Every batch. Spot-checking a product line and reusing that certificate across later batches is a common shortcut in this industry, and it's why lot-number matching matters so much.

What if my COA and my vial don't match?

Contact us immediately at aloha@dissolvlabs.com. A mismatch between the lot on your vial and the lot on your certificate is a legitimate problem and we'll resolve it.

Why is purity ≥99% and not 100%?

Because 100% doesn't exist in peptide synthesis. Any supplier claiming it is either rounding, or not measuring. The remaining fraction is normally residual solvent, water, and closely-related peptide fragments left over from manufacturing.
