Answers, before you ask.

Qualified parties, 18 or older, ordering for laboratory research use in an appropriate, approved setting. You confirm this on entry and again at checkout. The checkout confirmation is required — an order cannot be placed without it.

You can check out as a guest. An account is worth having anyway: your certificates are filed there by lot, against the exact vials you were sent.

Per compound, by quantity, applied automatically in the cart. Three or more saves 10% each, five or more saves 15%, ten or more saves 20%. No code to enter. The tiers are printed on every product page.

Pre-built kits are priced below the sum of their parts. See the kits.

Before it is dispatched, yes — write to us with the order number and we will catch it if it is still with us. Once a parcel has left, it has left. Because dispatch runs within two business days, that window is genuinely short, so write sooner rather than at the end of the day.

Yes, and we read every one of them. Tell us which compound belongs on the shelf. We will not stock something we cannot get a clean third-party certificate for, so a request is not a promise — but the list genuinely shapes what gets sourced next.

The same vials, from the same stock, hand-packed. A kit is not a separate production run and not a different grade of material — it is the singles, gathered, at a price below the sum of them.

Every lot is tested by an independent third-party laboratory before it reaches us, then tested again in our own laboratory when it arrives. Purity by HPLC, identity by mass spectrometry.

The third party goes first, on purpose. A supplier who tests its own material and then sends it out for confirmation has already decided what the answer should be. We don’t grade our own work.

How we verify.

They answer different questions. HPLC asks how much of this sample is one substance — it separates everything in the vial and measures the area under each peak, which is where a purity percentage comes from. Mass spectrometry asks whether that substance is the right one, by weighing it.

A sample can be 99.8% pure and be 99.8% pure something else entirely. Purity without identity is not verification, and identity without purity tells you the right molecule is in there somewhere.

A named testing laboratory you can look up and contact. A lot number that matches the number printed on the vial in your hand. The actual HPLC chromatogram, not just a typed percentage. A mass spectrum showing the observed mass against the theoretical mass for that molecule. And a date.

A certificate missing the lab’s name, or carrying a lot number that matches nothing on your vial, is a picture of a document rather than a document. Ours are searchable by lot in the COA lookup and filed against your order.

Because the shape carries information the number throws away. Two lots can both report 99.1% and look nothing alike: one with a single clean peak and a flat baseline, the other with a shoulder on the main peak where a closely related impurity is hiding, or a cluster of small peaks that a shallow integration has quietly folded into the solvent front.

A typed percentage can be produced by anyone with a keyboard. A chromatogram takes an instrument.

Into things that are chemically close to the target and unavoidable in synthesis. Deletion sequences, where one residue failed to couple and the chain is a residue short. Truncations. Oxidised forms, where a methionine has picked up an oxygen and gained sixteen daltons. Fragments from cleavage.

Nothing reaches 100%, and a supplier claiming it either is not measuring or is not telling you what they measured. Our specification is 99%+, documented, or it does not enter the catalog.

This is the distinction most often blurred in this industry, so it is worth being exact about.

Purity is what fraction of the peptide present is the correct peptide. It is what the HPLC number reports.

Peptide content is what fraction of the powder’s mass is peptide at all — the rest being residual water and counter-ions, most often trifluoroacetate left over from purification.

A vial can be 99% pure and still be perhaps 80% peptide by mass, and both figures are honest. They measure different things. A supplier quoting only the flattering one is telling you something.

99%+, documented, or it does not enter the catalog. The number on the certificate is the number in the vial. No exceptions.

In your account, filed against the order, and searchable by lot number in the COA lookup. The certificate belongs to the vial in your hand — not to a representative batch from some earlier run.

Because it is the only thing tying a document to a vial. A certificate with no lot number, or with a lot number that appears nowhere on your packaging, is evidence about some material somewhere — not about yours.

Check it. It is printed on the vial and it is the field the lookup searches on.

No. Material that fails either test does not enter the catalog, and there is no second grade, no B-stock and no discount tier for it. That is the whole reason the shelf is as short as it is.

Yes — here. Enter the mass in the vial and the volume of diluent and it returns the concentration in mg/mL, mcg/mL, and mcg per 0.01 mL, plus a reverse solver for working back from a target concentration.

It computes concentration and nothing else. It will not convert that concentration into an amount to administer to anything, and it never will.

The difference is a preservative. Bacteriostatic water contains 0.9% benzyl alcohol; sterile water contains nothing but water.

Which is appropriate depends entirely on the protocol and on how long the solution needs to hold, and that is the researcher’s decision, not ours. We will describe what each one is. We will not tell you which to use.

Peptides are surface-active. Shaking drives air into the solution, peptide molecules collect at every air-water interface it creates, and the foam that results carries material out of solution and onto the glass. What you lose that way does not come back when the foam settles.

Direct the diluent down the wall of the vial rather than onto the powder cake, then swirl gently or simply wait. Lipidated peptides — retatrutide especially — punish agitation hardest.

Almost certainly not. Ten milligrams of lyophilised peptide is a very small amount of material, and freeze-drying leaves a light, porous cake that can shift during transit or cling to the stopper rather than sitting flat at the bottom. Some vials look nearly empty.

Weight, not appearance, is what the certificate records. If you have a genuine reason to think a vial is short, tell us with the lot number.

Lyophilised vials are commonly sealed under vacuum or under an inert gas, and you may see the diluent drawn in as the seal is pierced. Whether a given vial holds a strong vacuum after shipping is not a reliable quality signal on its own — seals equalise slowly, and altitude changes in transit do the rest.

A broken or lifted stopper is a different matter. Tell us.

Kept at −20 °C, dry, and out of the light, lyophilised powder is stable for a long time — months to years depending on the compound. In solution the picture changes completely, and the working life is far shorter.

The vial label and the certificate govern. Where they differ from anything written here, they win.

Freezing and thawing repeatedly is what does the damage — each cycle concentrates solutes at the ice front and puts the molecule through a mechanical wringer. If a solution must be frozen, aliquot it into single-use volumes before the first freeze, so nothing is thawed twice.

The larger and more folded the molecule, the less it tolerates. IGF-1 LR3, an 83-residue protein with three disulphide bonds, is the least forgiving item in the catalog on this point.

Because that is what those molecules look like. GHK-Cu is a copper(II) complex and the blue is the copper — a white GHK-Cu powder would be the thing to worry about. 5-Amino-1MQ is an aromatic quinolinium iodide, and yellow to orange is its natural colour.

Everything else in the catalog is a white lyophilised powder. Colour where colour is not expected is worth telling us about; colour where it belongs is chemistry. See the compound reference.

Lyophilised powders are shipped at ambient temperature by design and tolerate transit warmth — the dry state is what makes them robust. Anything requiring cold chain is packed for it and marked as such.

If a cold-chain parcel arrives warm, or if a powder has visibly clumped, melted or discoloured, tell us with photographs and the lot number before opening anything further.

As the vial label directs. Lyophilised powders ship at ambient temperature; anything requiring cold chain is packed for it and marked. Bring a cold vial to room temperature before opening it, so condensation does not form on the powder. Handle as you would any research chemical of unknown hazard.

In-stock orders are dispatched within two business days, Monday to Friday. Orders placed after 2:00 PM MST count from the following business day. Tracking is emailed the moment the parcel leaves us.

On orders of $300 or more within the United States, yes. Below that, rates calculate at checkout against your address. Full shipping terms.

Not at present. We ship within the United States only.

Research chemicals crossing a border raise customs and import questions that vary by country and that we are not in a position to answer for you. Rather than ship and hope, we do not ship.

Plain outer packaging, no product or category markings, tamper-evident seals, tracked end to end. Tracking is emailed on dispatch.

Write to us with the order number and the tracking number. For damage, photograph the outer box and the vials before unpacking any further — that is what a carrier claim needs and it cannot be reconstructed afterwards.

No, and we would rather say so plainly. We source material, require an independent third-party certificate on it before it ships to us, and test it again in our own laboratory when it arrives. Our name goes on the verification, not on the synthesis.

Because the standard is the constraint, not the ambition. A compound enters the shelf when we can get it clean, get it documented, and get it verified twice — and not before. A long catalog is easy to build and hard to stand behind.

Tell us what is missing.

No. Anything that is a prescription drug is outside what this shop is for, and we have removed items from the catalog on that ground. We are a chemical supplier for laboratory research — not a pharmacy, not a compounding pharmacy, and not an outsourcing facility under sections 503A or 503B.

In the compound reference. Sequence, molecular formula, molecular weight, CAS number, origin, solubility and storage for every item in the catalog — and where published sources disagree on a figure, the figure is left out rather than averaged.

No. Most compounds are stocked in a single vial size at the moment, and the dropdown shows you that size rather than hiding the field. When a second size arrives it appears there. Kits have no size field, because a kit is a collection of vials rather than one.

These compounds are supplied for laboratory research. They are not drugs, supplements, or food, and they are not for human or animal consumption. Alpha Aminos is a chemical supplier — not a compounding pharmacy, and not an outsourcing facility under sections 503A or 503B of the Federal Food, Drug, and Cosmetic Act.

No. We describe the molecule, the testing, and the certificate — structure, sequence, purity, identity, lot. We do not describe effects, and we cannot advise on use. That line is not negotiable, and it is the same line every reputable supplier holds.

We will answer any question about the material: what it is, what it weighs, how it was tested, what the certificate says, how it should be stored. We will not answer a question about what to do with it. That is not evasion — a supplier that gives protocol guidance has stopped being a supplier.

Once on entry, so nobody browses under a misunderstanding. Once at checkout, because that is the acknowledgment tied to the purchase itself. The second one is the one that matters.
