Original Peptide Review: COAs, Prices & Policies

Original Peptide publishes a public COA library whose sampled certificates can be checked on the testing laboratory's own website. On November 2, 2026, three reports we opened matched BioRegen's online verification records. Its return-policy page, however, repeated the shipping policy and stated no return terms. This review separates those documents from unverified product-quality and delivery claims.

This review covers published documents and a separately documented October 23 cart test, not hands-on product performance.

Is Original Peptide legit? Our evidence-limited assessment

Original Peptide is a research-peptide storefront with publicly accessible laboratory certificates, three of which PeptideStack matched to records returned by BioRegen on November 2, 2026. However, this does not establish the company's corporate registration, the quality of products shipped to customers or its refund practices. Its return-policy page contains no return terms, and one reviewed GHK-Cu certificate has no batch number.

We cannot independently establish the vendor's overall reliability from the available evidence. Weigh those gaps before ordering, and obtain lot-matched documentation for the item you buy.

We did not find a reliable independent customer-feedback sample; the Trustpilot address we tried did not display a review page. We therefore assign no rating and present no testimonials.

The Terms state products are for research purposes only and not for human consumption, medical use or therapeutic application. The Terms give 18 as the minimum age to purchase, while the site's entry gate and disclaimer say 21. Our peptide vendor reviews cover other documented suppliers.

What did PeptideStack verify about Original Peptide?

PeptideStack checked Original Peptide's COA library, three certificate PDFs, the laboratory's verification records, two product pages, and its shipping, return, terms and contact pages on November 2, 2026. The table separates what the pages show from what we did not test.

Topic	Observed evidence	Limit
Business identity	The site footer reads "Original Peptide Inc." The About page describes a research peptide supplier.	We did not verify corporate registration, ownership, location or founding date.
Testing	A public COA library lists 26 certificates; three sampled reports were returned by BioRegen's verification page.	We did not match a report to a purchased vial or test any product ourselves.
Pricing	GHK-Cu 50mg listed at $49 (in stock); GHK-Cu 100mg at $63 (out of stock).	Listing prices are not a completed-order total or evidence of vial contents.
Fulfillment	The shipping policy states US-only shipping and flat rates.	We did not place an order or measure processing, delivery or support response times.
Coupon	Our Original Peptide coupon page records the October 23 cart result.	The test covered one item in a signed-in session, not every product or a guest checkout.

Does Original Peptide publish batch COAs?

Yes. Original Peptide's COA library listed 26 certificate PDFs on November 2, 2026, covering products such as GHK-Cu, BPC-157, NAD+, MOTS-C, Semax and several blends.

We opened three of those PDFs. Each identifies BioRegen as the testing laboratory, Original Peptide as the client, and UPLC-MS (ultra-high-performance liquid chromatography with mass spectrometry) as the method.

Certificate	Product and lot	Reported result	Analysis date
COA #11771	GHK-Cu 50mg, lot T2503-021	Identity conforms; purity 99.65%	January 6, 2026
COA #11793	BPC-157 10mg, lot T2506-001	Identity conforms; purity 99.64%	January 7, 2026
COA #12468	GHK-Cu (listed for 100mg), lot shown as N/A	Identity conforms; purity 99.42%	March 9, 2026

BioRegen's COA verification page asks for a certificate number and the security key printed on the report. For all three certificates, it returned a downloadable report named for Original Peptide and the same product. An incorrect key returned "No matching post found."

A verified certificate shows that a laboratory record exists for a submitted sample. It does not prove that a vial you receive comes from that lot. These reports cover identity and purity by UPLC-MS; they do not report sterility, endotoxin levels or the filled quantity of every marketed vial.

The GHK-Cu 100mg certificate is listed under COA ID 89030-95-5, while certificate #12468 states "Batch/Lot #: N/A." The GHK-Cu product pages display a different CAS identifier (300801-03-0), so the published documents do not establish an unambiguous lot match for a specific 100mg vial. Ask the merchant which lot will ship before relying on any certificate.

What is Original Peptide's return and refund policy?

We could not find one. The Return Policy page displayed the same seven shipping sections as the shipping policy on both October 30 and November 2, 2026. It stated no return window, refund condition or damaged-order process.

The Terms and Conditions say Original Peptide may refuse or cancel any order at its discretion. If returns, refunds or damaged-order remedies affect your decision, ask the merchant to state them in writing before ordering.

Where does Original Peptide ship, and what does shipping cost?

The Shipping Policy, dated January 1, 2026, says Original Peptide ships within the United States only.

• California: flat rate of $11.00.
• Other eligible states: flat rate of $18.00, shown at checkout.
• Processing: after payment confirmation and order review; the policy gives no fixed processing time and reserves the right to hold orders for review.
• Delivery: estimates only. Tracking "may be provided" after shipment, when available.
• Carrier issues: the policy disclaims responsibility for carrier delays, lost or damaged packages once an order is handed to the carrier.

These are published policies, not delivery results measured by PeptideStack. Confirm the shipping charge shown at checkout for your address before ordering.

What products and prices did we check?

Original Peptide sells lyophilized research compounds as single vials and blends. We checked two GHK-Cu listings on November 2, 2026.

Product listing	Listed price	Stock shown	Price per labeled milligram
GHK-Cu 50mg	$49.00	In stock	$0.98
GHK-Cu 100mg	$63.00	Out of stock	$0.63

The product pages display "99% Purity" and "Made In USA" labels. These are merchant claims; we did not verify manufacturing location. Per-milligram figures use the labeled quantity, exclude shipping, tax and discounts, and can change.

How can you contact Original Peptide support?

The contact page offers a contact form for order, product, documentation and account questions, and the site displays the phone number 1 (800) 871-3999. We did not contact support, so we cannot report response times or quality.

What did the OPPSTACK10 coupon test establish?

OPPSTACK10 applied a 10% discount to one GHK-Cu 50mg vial in PeptideStack's October 23, 2026 signed-in cart test. The $49.00 subtotal fell by $4.90 to $44.10 before shipping and tax; no purchase was made.

That does not establish guest eligibility, sitewide applicability, stacking or a final delivered price. The test was not repeated for this review. See the Original Peptide coupon code and cart test for redemption steps.

The merchant's storefront is Original Peptide (paid link). The cart showed no discount until OPPSTACK10 was entered manually.
