Save up to 30% with American Peptides LOOT10. Explore the 2026 research catalog, COAs, pricing, bundles, shipping, and a practical sourcing checklist.

If you are comparing research-peptide suppliers, American Peptides is worth examining for its emphasis on lot-specific documentation, third-party testing, and a broad research catalog. For the August 2026 promotion covered in this guide, the supplied code LOOT10 is advertised as providing up to 30% off through the promotion page.

Quick reference

Supplier: American Peptides
Category: Research-use laboratory materials
Documentation: Lot-matched Certificates of Analysis (COAs), HPLC and mass-spectrometry testing information
Catalog: Research peptides, GLP-1/metabolic research compounds, peptide blends, nasal sprays, dissolving strips, bioregulators, research bundles, lab supplies, and merchandise

American Peptides states that its products are supplied for laboratory and research use only, not for human or veterinary consumption. This guide therefore focuses on supplier evaluation, documentation, catalog organization, pricing, purchasing considerations, and research-material sourcing rather than human use, dosing, or administration.

What American Peptides Actually Sells

The catalog is broader than a simple list of individual research peptides.

The current American Peptides catalog is organized across nine major categories, including GLP-1/metabolic compounds, individual research peptides, peptide blends, nasal sprays, dissolving strips, bioregulators, research bundles, lab supplies, and merchandise. The company's current homepage lists 66 research compounds/products across these categories.

The individual research-peptide catalog includes compounds such as:

AOD-9604
ARA-290
BPC-157
DIHEXA
DSIP
GHK-Cu
HUMANIN
IGF-1 LR3
IPAMORELIN
KISSPEPTIN-10
KPV
L-GLUTATHIONE
MELANOTAN-1
MELANOTAN-2
MOTS-C
NAD+
P-21
PE-22-28
PT-141
SELANK
SEMAX
SERMORELIN
SS-31
TB-500
TESAMORELIN
THYMOSIN ALPHA-1

The company's research-peptide collection currently lists 27 individual products, with displayed prices ranging from approximately $40 to $150 and above, depending on compound and quantity.

That breadth matters for laboratory sourcing because a researcher can evaluate multiple material categories from one supplier. It also means each individual compound still needs to be evaluated on its own specifications and documentation rather than assuming that every product has identical characteristics.

How to Evaluate an American Peptides Product Before Purchase

Start with identity and documentation, not price.

A discounted research material is not automatically a good purchase if the compound, strength, lot documentation, or specifications do not match the requirements of the project.

A practical sourcing checklist is:

Confirm the exact compound name.
Confirm the available strength or quantity.
Review the product specifications.
Locate the lot-matched Certificate of Analysis.
Review the analytical methods shown on the documentation.
Match the lot number with the material being purchased.
Check the testing date and laboratory.
Review shipping and cancellation terms.
Compare one-time, volume, subscription, bundle, and promotional pricing.
Retain the relevant documentation in the laboratory's records.

American Peptides maintains a dedicated COA library where users can search products and review available batch documentation. The company says its research compounds are independently third-party tested for identity and purity, with HPLC and mass-spectrometry verification.

American Peptides COA Library

What to Look for in a Peptide COA

A Certificate of Analysis should be treated as a technical document rather than simply a marketing badge.

For research sourcing, useful questions include:

Does the document identify the exact compound?
Does the lot number match the material?
Is identity testing described?
Is a purity result reported?
Is the testing laboratory identified?
Is the testing date visible?
Are analytical methods stated?
Are other relevant specifications documented?

American Peptides describes its standard as ≥99% analytical purity, with HPLC and mass-spectrometry testing. Its COA library publishes lot-specific reports, while relevant products may also have Safety Data Sheets available.

This is more useful than simply seeing a generic statement such as "99% pure." The important question is whether the claim is connected to the specific batch being purchased.

Why Lot Matching Matters

Imagine two vials carrying the same product name but different batch numbers.

A generic COA tells you something about a product category. A lot-matched COA connects the analytical report to a particular production batch.

That distinction is useful when reproducibility and traceability matter.

American Peptides says its COAs are indexed by lot and that its batches are independently tested. Some current product pages also display detailed testing information directly alongside the product specifications.

For example, individual product pages can show:

Product strength
Purity
Testing laboratory
Testing method
Batch number
Testing date
COA availability
Storage information

That makes the product page itself a useful first step before moving to checkout.

Pricing: How to Compare the Real Cost

The listed one-time price is not necessarily the only price available.

Current American Peptides product pages show several purchasing mechanisms:

One-time purchase pricing
Subscribe & Save on selected products
Volume pricing on selected products
Research bundles
Promotional discounts when an applicable code is available

For example, current pages for products such as MOTS-C, SS-31, AOD-9604, and BPC-157 show automatic volume tiers. Selected products become cheaper per unit as quantity increases.

Some products also show Subscribe & Save savings of up to 15%, depending on the product.

A better way to compare cost is:

Effective purchase cost = listed price − applicable promotional savings − applicable volume savings

The exact checkout rules determine whether different discounts can be combined, so do not assume that every available discount stacks automatically.

How LOOT10 Fits Into the August 2026 Promotion

For this guide, the supplied August 2026 promotion is:

PROMO CODE: LOOT10

ADVERTISED SAVINGS: UP TO 30% OFF

Start with the dedicated promotion page:

American Peptides LOOT10 promotion page

The practical process is straightforward:

Open the promotion page.
Browse the research catalog.
Select the material that matches the laboratory requirement.
Review the product specifications.
Locate the relevant COA.
Add the product to the cart.
Enter LOOT10 in the applicable discount field.
Confirm the discount shown at checkout.
Review shipping and cancellation terms.
Complete the purchase only after confirming the final total.

Because promotional terms can change, the checkout total should be treated as the final confirmation of the actual savings applicable to a particular cart.

Single Compounds vs. Research Bundles

Single compounds make sense when a research project requires a specific material and defined quantity.

Bundles can make more sense when the research requirement already includes multiple materials.

American Peptides currently lists bundles including:

GLOW Bundle
IMMUNO Bundle
IRONCLAD Bundle
KLOW ELITE Bundle
NAD STACK Bundle
NEURO Bundle
PRIME Bundle
PULSE Bundle
REPAIR+ Bundle
WOLVERINE Bundle

The company describes these as curated multi-vial research stacks sold at a saving compared with buying the individual compounds separately.

American Peptides Research Bundles

The important point is not to buy a bundle simply because the headline price looks attractive. Compare the individual components against the actual research requirement.

Unused material is not a saving.

Understanding the Wider American Peptides Lineup

American Peptides has several distinct product categories.

Research Peptides

The single-compound catalog covers a wide range of research materials, including BPC-157, GHK-Cu, MOTS-C, SELANK, SEMAX, SS-31, TB-500, and numerous others.

GLP-1 and Metabolic Research Compounds

The site also maintains a separate category for compounds associated with metabolic and receptor-signaling research. These products remain within the company's stated research-use-only framework.

Peptide Blends

The catalog includes combination research materials that contain multiple peptides in a single product.

Nasal Sprays and Dissolving Strips

American Peptides also lists alternative research-material formats such as nasal sprays and dissolving strips. These should still be evaluated according to their stated specifications and research-use-only labeling.

Bioregulators

The current bioregulator category includes products such as Epithalon, Pinealon, Prostamax, Testagen, Thymalin, Vesugen, and Vilon.

Research Bundles

Curated multi-product bundles provide another purchasing option for laboratories requiring multiple research materials.

Lab Supplies

The company also sells laboratory-related supplies, including prep pads and other supporting products.

Merchandise

The wider catalog also includes branded merchandise.

This broader lineup can be useful for laboratories that prefer to consolidate sourcing, but the same rule applies: evaluate each individual material and its documentation rather than treating the entire catalog as one homogeneous product.

Shipping, Cancellation, and Returns: Check These Before Ordering

Price is only one part of supplier evaluation.

American Peptides currently states that orders are generally processed and dispatched within 24–48 business hours, with tracking information provided after shipment. Its terms also state that shipping is limited to the continental United States.

The refund policy deserves attention before checkout.

The company states that research-peptide sales are generally final after shipment, while verified damaged or incorrect shipments can qualify for replacement under its policy.

The cancellation policy states that one-time orders can be cancelled before they are processed for shipment. Subscribe & Save subscriptions have a separate cancellation process before the next billing date.

For a laboratory purchaser, the takeaway is simple:

Check destination restrictions, cancellation timing, shipping costs, and final-sale conditions before payment.

Storage and Research-Material Handling

American Peptides publishes a separate research guide covering storage and stability considerations for lyophilized and reconstituted research materials.

American Peptides Peptide Storage & Stability Guide

The company's stated purpose for that resource is research-material stability rather than human-use guidance.

For laboratory purchasing, this highlights an important point: supplier quality is only one part of reproducibility.

Once a material arrives, documentation, labeling, storage, and controlled handling become part of the laboratory's own quality process.

A basic recordkeeping workflow can include:

Product name
Lot number
Date received
Quantity received
COA location
SDS location
Storage location
Internal project identifier
Date opened, where applicable
Shipping or packaging issues

How to Decide Whether American Peptides Fits Your Research Workflow

American Peptides is particularly worth evaluating when your sourcing priorities include:

Lot-specific documentation
Third-party testing information
HPLC and mass-spectrometry results
A searchable COA library
A broad research catalog
Volume pricing
Research bundles
Domestic U.S. fulfillment

The company also states that it offers wholesale or bulk pricing for eligible research organizations and verified partners.

The main limitation is the size of the catalog itself.

More products mean more product pages, strengths, formats, lots, and documents to compare. That is not necessarily a weakness, but it does mean a disciplined purchasing process matters.

A Practical American Peptides Research-Buying Checklist

Before placing an order, run through this checklist:

□ Is this the exact compound required by the research project?
□ Is the strength and quantity correct?
□ Is the product explicitly designated for research use?
□ Can I locate the lot-matched COA?
□ Does the lot number match?
□ Are identity and purity results documented?
□ Is the testing laboratory identified?
□ Have I reviewed the SDS where relevant?
□ Have I compared one-time, volume, bundle, and subscription pricing?
□ Have I applied LOOT10 and confirmed the checkout total?
□ Have I reviewed shipping restrictions?
□ Have I reviewed cancellation and final-sale rules?
□ Does the quantity actually make sense for the project?

This takes longer than simply clicking "Add to Cart," but it is much closer to a serious laboratory sourcing decision.
