Penguin Peptides

penguinpeptides.com · Est. ~2025 · Sheridan, WY · EIN: 33-4847033 · Scored August 2026

Penguin Peptides operates a publicly accessible site with a dedicated Lab Results page at penguinpeptides.com/lab-results/ hosting 40+ COA images across the full catalog. However, these are product-level PNG files - labeled by product name and vial size (e.g., "GLP-3R 5mg Purity") - not batch or lot-specific documents. A researcher cannot verify whether a given COA image corresponds to the specific lot they received. No testing laboratory is named anywhere on the site. The vendor publishes its EIN (33-4847033) and a physical address (1309 Coffeen Avenue STE 1200, Sheridan Wyoming 82801) - a registered agent address common to Wyoming LLCs - along with a phone number and active social media. ScamAdviser rates the domain at 0/100 due to its young age and hidden WHOIS ownership. An independent review also flagged anomalous Trustpilot review patterns including a review volume spike inconsistent with organic growth.

Dimension Scores
DimensionMaxNotesScore
Third-Party Testing Practice 30 Third-party testing by "U.S.-based third-party laboratories" stated on homepage and About page. No testing laboratory is named by facility name, address, or credentials. 40+ COA images are publicly hosted on the site. Without a named lab, the testing claim cannot be independently evaluated. Partial credit for the volume of publicly hosted COA images, which suggests an active testing program even if unverifiable by source. 10/30
Batch Traceability & Verification 20 COA images on the Lab Results page are organized by product name and vial size (e.g., "GLP-3R 5mg Purity", "BPC 157 10mg") - not by batch or lot number. A researcher cannot determine whether the COA on the page corresponds to the specific production lot in their vial. Product-level COAs are not batch-traceable documentation. No lot-to-COA linkage system exists. This is the most significant single documentation gap for this vendor. 4/20
COA Accessibility 15 Lab Results page at penguinpeptides.com/lab-results/ is publicly accessible without login (age-gate checkbox only). 40+ COA images are viewable and downloadable. The page is linked directly from the main navigation. Credit for genuine public accessibility; deduction for product-level rather than batch-specific documents and the absence of any independently verifiable lab origin on the documents themselves. 10/15
COA Completeness 15 COA images are hosted as PNG files. Without viewing the actual COA content in detail, the analytical scope cannot be fully assessed. From the filenames and the site's third-party testing claims, HPLC purity is the primary documented method. No mention of sterility, endotoxin, or heavy metals testing. Lab not named, preventing scope verification. 5/15
Testing Recency 10 COA image filenames show February 2026 and June 2026 upload dates, confirming recently uploaded documentation. Domain established approximately April 2025, making the operation roughly 16 months old at time of scoring. All documentation is recent by definition for a young vendor. 5/10
Policy Transparency 5 EIN (33-4847033) published in the homepage footer - an unusual and notable disclosure for this market. Physical address (1309 Coffeen Avenue STE 1200, Sheridan Wyoming 82801) and phone number (951-262-0000) published. Refund Policy, Shipping Policy, Terms of Service, and Privacy Policy linked from the site footer. Sheridan, Wyoming address is a registered agent mailbox common to Wyoming LLCs and does not confirm a physical operating location. WHOIS ownership hidden. ScamAdviser 0/100 rating and anomalous Trustpilot review patterns are external signals documented here. 3/5
Operational Track Record 5 Domain registered approximately April 2025. Approximately 16 months of documented operation at time of scoring. WHOIS ownership hidden. ScamAdviser domain trust score of 0/100 based on domain age and hidden registration. Trustpilot review volume and pattern flagged as anomalous by independent review analysis. Social media presence active across Facebook, Instagram, Twitter, YouTube, Pinterest, TikTok. 1/5
Total 38/100
Community Signal
Independent Test Results
No community-commissioned independent test results identified in public forums as of August 2026. No presence in the Finnrick or other public independent testing datasets at time of scoring. This field will be updated as independently sourced results are published.
Community Signal Flags
PeptideGrades' independent review documented anomalous Trustpilot review patterns - a high review volume spike described as inconsistent with organic growth for a vendor of this age. PeptideClear does not independently verify this finding, but documents it as a community signal. The Trustpilot profile itself shows a high overall rating across the volume of reviews. ScamAdviser's 0/100 rating is based on domain age and hidden WHOIS, not on documented fraud. These are signals, not conclusions.
Scoring Notes
Product-level COAs are not batch-level COAs
The distinction matters for research integrity. A batch-level COA confirms that the specific production lot in a researcher's vial was tested and passed. A product-level COA - labeled by product name and size, not lot number - confirms that some batch of that product was tested at some point. If manufacturing consistency varies across batches, a product-level COA does not confirm the quality of the vial received. This is the most material transparency gap for this vendor.
EIN disclosure is notable for this market
Publishing an EIN (Employer Identification Number) in the homepage footer is unusual for research peptide vendors - most do not disclose tax registration numbers publicly. An EIN is verifiable through IRS tools and is a meaningful accountability anchor. Combined with the physical address and phone number, Penguin Peptides provides more entity-level disclosure than most Low band vendors, which is reflected in the Policy Transparency dimension score.
