Simms Research Review: COAs, Payments & Policies

Simms Research publishes 53 batch lab reports from two named laboratories, and the two reports we opened name Simms Research as the client. The Tampa, Florida store takes cards, Apple Pay, Google Pay and Klarna, and publishes a free Delivery Guarantee. This review separates what its public pages showed on October 30, 2026 from product quality, delivery and support claims we did not test.

Paid listing disclosure: Simms Research paid PeptideStack for a listing. PeptideStack may also earn a commission from purchases using PSTACK. Payment does not independently verify the merchant's products, certificates or claims. We have not purchased, used or laboratory-tested Simms Research products. This review covers the merchant's public pages as read on October 30, 2026, not hands-on product performance.

What did PeptideStack verify about Simms Research?

PeptideStack read the Simms Research homepage, catalog, lab-results page, About, FAQ, Payment Options, Shipping Policy, Refund & Return Policy, Terms and Conditions and contact page on October 30, 2026. The table separates what those pages show from what we did not test.

Topic	Observed evidence	Limit
Business identity	The Privacy Policy names Simms Research LLC; the site footer lists 5908 Breckenridge Pkwy, Tampa, FL 33610.	We did not check state business records or visit the address.
Testing	The lab-results page links 53 merchant-hosted certificates, each tied to a batch number and test date.	We did not independently authenticate the certificates with the issuing laboratories or test any product.
Pricing	The shop showed listed prices for 35 catalog listings.	Listed prices are not a completed-order total or evidence of actual vial contents.
Fulfillment and support	The Shipping Policy describes same- or next-business-day dispatch; the contact page lists email, phone and support hours.	We did not place an order or measure delivery or response times.
Coupon	PeptideStack's partnerships team recorded PSTACK with Simms Research on October 30, 2026.	A discount code is not evidence of product quality or safety.

Does Simms Research publish COAs?

Yes. On October 30, 2026, Simms Research's lab-results page reported 53 tested batches across 23 products, with a batch number, purity figure, test date and linked certificate for each. Thirty-three certificates were attributed to Freedom Diagnostics and twenty to Kovera Labs. Product pages repeat the batch history for the products covered.

The page's listed purity results ranged from 99.13% (BPC-157 batch B164, December 3, 2025) to 99.97% (Tesamorelin batch TN544, May 5, 2026). The newest reports, dated July 16 and 17, 2026, are the Kovera Labs set. These 20 certificates cover 20 reported batches, and each lists three submitted vials, together with endotoxin, heavy-metal and microbial screening results. Most older Freedom Diagnostics entries list one vial tested and HPLC-UV or HPLC purity; several show endotoxin as “Not Tested.”

PeptideStack downloaded all 53 merchant-linked certificates and recorded the laboratory named on each. The batch, method and screening details above come from the lab-results page. The two BPC-157 examples below illustrate certificate-level detail. We did not independently authenticate any certificate with its issuing laboratory.

• BPC-157 10mg, Kovera Labs: report KVR-2026-6C21A4, certified July 16, 2026, batch 2026-B670. The client field reads Simms Research. It lists a three-vial average purity of 99.651%, average net content of 10.19 mg, identity confirmed by LC-MS, an endotoxin screen marked Pass, fentanyl not detected, a microbial sterility screen marked No Growth, and negative results for arsenic, cadmium, lead and mercury. It gives an access code for koveralabs.com/verify.
• BPC-157 10mg, Freedom Diagnostics: accession number 2716600784, received April 28, 2026 and reported April 29, 2026, lot B544. The client field reads Simms Research. It lists 99.41% purity by HPLC-UV, 11.29 mg net content, identity confirmed by LC-MS and two endotoxin replicates marked Pass, with a search code for checking the report.

A certificate shows what the vials submitted from one batch measured. It does not establish that the vial you receive came from that batch, and a sterility screen on sampled vials is not proof that every vial is sterile. The analytical findings reported on a certificate do not independently establish regulatory compliance, suitability for human use, or the quality of unsampled inventory. Several reports also list net content above the labeled amount; for example, Retatrutide batch R30 lists 11.95 mg for a 10mg label. PeptideStack did not complete a lab-side check of either report.

What documentation does Simms Research provide?

• Merchant identification: Both BPC-157 certificates examined in detail name Simms Research as the client and include batch identifiers listed by the merchant.
• Batch history: Each covered product shows dated results for earlier batches, not only the latest certificate.
• Broader 2026 screens: The July 2026 Kovera Labs reports list three vials per batch plus endotoxin, heavy-metal and microbial screens.
• Card payments: The store accepts major cards and mobile wallets, and says card charges appear as SIMMSRESEARCH.COM with no payment-method surcharge.
• Published contact channels: support@simmsresearch.com and 855-592-8507, with stated hours of 9 AM to 5 PM EST, Monday to Friday. PeptideStack did not test response times.

What evidence gaps did we find?

• No report located during our October 30 check: We found no published certificate on the lab-results page or product pages for AOD-9604, PT-141, Kisspeptin-10 or SS-31. The About page says, “If we can't show the test, we don't ship the batch.”
• Uneven older testing: Several earlier batches list one vial and no endotoxin, heavy-metal or sterility result.
• Laboratory claims: The About page describes an “independent ISO-certified laboratory.” PeptideStack did not verify either laboratory's accreditation.
• Dosing content: The FAQ says Simms Research does not provide dosing guidance, but its blog publishes a retatrutide dosage chart and calculator. PeptideStack does not provide or endorse dosing information.

What payment methods does Simms Research accept?

The Payment Options page lists Visa, Mastercard, American Express and Discover credit and debit cards, plus Apple Pay, Google Pay and Klarna where available. It says Simms Research does not accept cryptocurrency, Cash App or PayPal, and does not add a payment-method surcharge.

The page says card details go directly to the payment processor and that Klarna shows its own eligibility and terms before you confirm. Card and wallet charges are described as appearing as SIMMSRESEARCH.COM.

What are Simms Research's shipping and refund policies?

The Shipping Policy says orders ship the same or next business day, excluding Sundays and public holidays, and orders placed before 5 PM EST ship the same day. It offers UPS Standard, estimated at 3–5 business days after dispatch, and FedEx 2-Day Express, estimated at 2 business days after dispatch and free on orders over $200. These are estimates, not order-to-door guarantees. It says Simms ships to all 50 US states and internationally; international buyers pay any customs duties.

Sources: Refund & Return Policy and Shipping Policy, read October 30, 2026. The policy page is undated, so its terms may change. It states that “Every order includes a free Delivery Guarantee.” These are published terms, not outcomes PeptideStack observed. We did not file a delivery or refund claim.

What does Simms Research sell, and at what prices?

The catalog showed 35 listings on October 30, 2026: research peptides and blends such as Retatrutide, Tirzepatide, BPC-157, GHK-Cu, NAD+, MOTS-C, Semax and Selank, plus six bundles, research water and an injection pen listed as out of stock. The Terms say compounds are sold individually without supplies such as bacteriostatic water or syringes.

Product listing	Listed price on October 30, 2026	Price per labeled milligram
Retatrutide (GLP-3) 10mg	$84.00	$8.40
Retatrutide (GLP-3) 20mg	$129.00	$6.45
Retatrutide (GLP-3) 30mg	$159.00	$5.30
Retatrutide (GLP-3) 60mg	$259.00	$4.32

This compares listed sizes from the same merchant, not quality or value against other suppliers. The calculation uses the labeled quantity, not independently measured contents. Prices can change; shipping, tax and any discount are excluded.

The Terms also describe Simms Rewards: 5 points per $1 spent on products after discounts, 100 welcome points on a first order, and expiry after 12 months without an order. We did not create an account or redeem rewards.

How should researchers weigh this evidence?

Compare the documentation for the batch you would receive, not only a purity percentage on a results page.

• Batch link: Check that the batch number on the vial matches a published certificate for that product and size.
• Verification: Use the laboratory's own report number, search code or access code to check a certificate with the issuing lab.
• Coverage: Note which products have no published certificate and which batches lack endotoxin or sterility screens.
• Cost: Compare the same labeled quantity and the final checkout total, not only the headline vial price.

Our peptide vendor reviews cover other suppliers using the same documentary approach. This review does not rank Simms Research against a named competitor.

Is Simms Research legit? Our evidence-limited assessment

PeptideStack cannot establish Simms Research's overall legitimacy, product quality or fulfillment reliability from its public storefront and documents alone.

As of October 30, 2026, Simms Research identified its operating company and Tampa address, published contact details, described mainstream card and digital-wallet payment methods, and listed 53 batch-level laboratory reports. PeptideStack inventoried the linked certificates, but did not independently authenticate them with their issuing laboratories or laboratory-test any product.

Material limitations remain: no published certificate was located for four catalog products during our check, older batch reports have uneven analytical screening coverage, and the merchant's dosage content is inconsistent with its research-only FAQ.

PeptideStack has not assessed customer reviews, placed a test order or tested customer support. We assign no numerical or star rating, present no customer testimonials and make no product recommendation or safety certification.

Simms Research's Terms and Conditions, last updated October 3, 2026, require buyers to be at least 21 and state that all products are for research and laboratory use only. They are not for human consumption, medical, veterinary or diagnostic use.
