Peptide Plugs scores higher than Peptide Confidential on our transparency method (8.1 vs 7.6), and it has the highest score on our list. Its product pages give a Freedom Diagnostics accession code you can check on the lab's own site, it publishes its LLC and address, and it ships inside the US. Peptide Confidential ties every record to a code on the vial and is the only vendor we rate that keeps its rejected and withdrawn lots public, but it's a Calgary business with no legal entity, and US orders cross the border. Neither has independent test data. Peptide Plugs is #6 and Peptide Confidential #7 in our editors' order, which isn't sorted by score.
Notice: Research peptides are sold for in-vitro laboratory research only. They are not FDA-approved, not for human or animal consumption, and this page is not medical advice. This comparison covers supplier transparency only, based on public documentation. We didn't purchase or test products.

Verification: lab-side codes vs a full lot history
Peptide Plugs gives you the strongest single check on our list: an accession code on the product page that you can enter on Freedom Diagnostics' own COA search, so the certificate is confirmed by the lab rather than the vendor. Its main COA page doesn't show lot numbers, but product pages do (review).
Peptide Confidential links each lot record to the lab's document, and where the certificate prints the lab's verification code you can check it on the lab's site. What it adds is history: its lab reports page keeps lots that failed its check or were pulled from sale, with reasons. Its records copy only purity, its two labs are less established and unaccredited as far as we found, and two current records were corrected to "lot not confirmed" in October 2026 (review).

Business transparency
Peptide Plugs publishes Austin Research Products LLC at 126 Holmes Rd, Liberty Hill, TX, with Texas-law terms (terms). Peptide Confidential names its founder, Troy White, and publishes a Calgary phone number, WhatsApp and email, but no entity or street address.
Labeling
Both carry strict research-use text. Peptide Plugs loses points for benefit-named shop categories such as "Weight Loss" and "Sleep." Peptide Confidential's categories are neutral, and it records a research-use declaration with every order; its deduction is the code-named retatrutide listing.
Price check
| Item | Peptide Confidential (Oct 13, 2026) | Peptide Plugs (Sep 26, 2026) |
|---|---|---|
| MOTS-c 10 mg | CA$50 (about $35.04) | $30 |
| TB-500 10 mg | CA$60 (about $42.04) | $50 |
| Tesamorelin 10 mg | CA$69 (about $48.35) | $60 |
| Epitalon 10 mg | CA$55 (about $38.54) | $40 |
Peptide Plugs is cheaper on MOTS-c; Peptide Confidential is cheaper on TB-500, tesamorelin and epitalon. Peptide Confidential's automatic multi-vial discount lowers its prices further on 2+ vials.
Shipping and returns
Peptide Plugs ships by UPS within 1-2 business days, US only, and all sales are final. Peptide Confidential aims to ship the same business day from Calgary; US parcels clear customs with no quoted delivery window, and a seized parcel isn't refunded or reshipped (shipping policy). It does replace damaged, lost and lab-mismatched items. See peptide shipping and customs.
Independent testing
Neither has community test data. Finnrick listed Peptide Plugs with 0 tests and had no profile for Peptide Confidential on October 13, 2026. Peptide Plugs' accession codes let you confirm a certificate with the lab, which is the strongest check available for either vendor until independent results exist. See Janoshik vs Finnrick.
