Two vetted vendors, and both are good options. Licensed Peptides scores 9.5/10 and SKO Compounds 8/10. Licensed holds more COAs (143 against 22), while SKO is cheaper on 15 of 23 shared compounds before codes and 17 of 23 after PEPTIDEP10; the baskets before codes are nearly level at $1,668.95 and $1,673.12. Pick Licensed Peptides for archive depth and GLP-2T; pick SKO for exact-listing certificates, a broad price list or international delivery.

Licensed Peptides is lower on 8 of the 23 before codes, SKO Compounds on 15. After PEPTIDEP10 the split is Licensed Peptides 6, SKO 17. One standard amount of every comparable compound costs $1,668.95 at Licensed Peptides and $1,673.12 at SKO before codes, then $1,668.95 and $1,505.81 after them.
The gap is line-specific. Licensed Peptides is lower on GLP-2T at $46.00 per 10mg against $79.99, on MOTS-c at $35.00 against $79.99, on 5-Amino-1MQ at $37.80 against $109.98 and on Sermorelin at $114.99 against $199.98. SKO is lower on GHK-Cu at $7.00 per 10mg against $11.50, on NAD+ at $12.00 per 100mg against $26.00, on TB-500 at $59.99 against $99.99 and on KLOW Protocol at $18.75 per 10mg against $25.00. GLP-3R is the closest large line: Licensed Peptides is 6% lower before the code at $51.67 per 10mg against $55.00, and SKO moves ahead at $49.50 against $51.67 after PEPTIDEP10. GLP-3R and Selank are the two lines that flip to SKO once the code applies.
COA depth at Licensed Peptides, exact-listing coverage at SKO
Licensed Peptides publishes 143 distinct report identities across 233 analytical pages, issued by Vanguard Laboratory, Ethos Analytics and Janoshik. 116 have primary analytical pages and 27 have extended-panel or solvent pages only. Panels include HPLC purity and content, identity testing, ICP-MS metals, LAL endotoxin, USP <71> sterility, GC-MS residual solvents and ion-chromatography TFA. 81 reports contain at least four test categories, 85 include heavy metals and 70 include endotoxin, with 57 covering both.
Some of that record is authenticated at the laboratory. Ethos Analytics directly authenticated all eleven March reports, EA Sample IDs 26EA0318-035 through -045, as laboratory-issued Licensed Peptides reports. Five Janoshik reports match exact public records; analyzed October 9, 2025, they measure 99.664% to 99.896% purity. Exceptions stay visible. A February 20, 2026 SLU-PP-332 5 mg report says quantity Not Detected and purity n/a. The Cagrilintide/GLP-3R blend reports 18.8 EU/mg endotoxin, FOXO4-DRI 10 mg reports 6.23 EU/mg and ARA-290 16 mg prints Pass at 6.02 EU/mg. Dihexa report 26EA0526-056 remains a client/branding confirmation question.
SKO Compounds held 22 third-party reports across 19 compounds at the July 23, 2026 review. PeptidePrices independently checked Freedom Diagnostics report SKOC2607070524 for BPC-157 lot SKO-BPC-10-002: LC-MS identity confirmed, duplicate-vial HPLC purity of 99.39% and 99.38%, content of 9.22 mg and 9.46 mg, duplicate LAL endotoxin PASS at ≤0.05 EU/mL and microbial PCR PASS. Content came in 7.8% and 5.4% below label, which is why the site's claim of more than 99% purity should be read against the exact batch report.
The coverage numbers cut both ways. Only 4 of Licensed Peptides' 58 in-stock listings carry an exact issuer-verified certificate, all from Janoshik. SKO has 24 of 34, from Freedom Diagnostics (19) and ILS Laboratories (5), with the newest matched analysis dated August 12, 2026. Licensed Peptides leads on archive depth and the COA factor. SKO leads on the narrower question of whether a certificate is attached to the listing in front of you. Neither library is complete: SKO's does not yet cover every listed compound or size, and Licensed Peptides' archive does not map to every live listing.
PEPTIDEP10 at SKO, no reader code at Licensed Peptides
SKO Compounds carries PEPTIDEP10 for 10% off. The offer is verified by PeptidePrices, checked on October 3, 2026, and it does not auto-apply, so enter it at checkout. Terms sit on the SKO Compounds coupon page.
Licensed Peptides has no PeptidePrices code. Its entry lists the code as none and the discount as 0%, with the offer verified by PeptidePrices, checked on October 3, 2026. There is nothing to enter at checkout.
The asymmetry is visible in the price table. Before codes, Licensed Peptides is lower on 8 of 23 compounds. After PEPTIDEP10, it is lower on 6. The Licensed Peptides basket stays at $1,668.95 because no code applies, while the SKO basket moves from $1,673.12 to $1,505.81.
Shipping reach: SKO lists international service, Licensed is unverified
SKO Compounds ships to the United States and internationally, and takes credit/debit card. Processing is same- or next-business-day, with 2-day and overnight options. The site shows conflicting $200 and $250 free-shipping thresholds, so the checkout total is the reliable number. Returns are generally not accepted, and damage or fulfillment claims have a short reporting window.
Licensed Peptides' destinations and payment methods are not verified in our data. Its published shipping policy describes US service, including outlying islands, with typically same-business-day handling for paid weekday orders before 4 PM Pacific. FedEx 2Day is free above $200 or for VIP members, USPS Ground Advantage is $8.95 and paid FedEx 2Day is $11.95. Eligible unused, unopened items in original packaging can be returned within 30 days of delivery, but the separate terms and conditions still say all sales are final, which conflicts with that policy. Shipping and return terms were checked October 18, 2026.
For an international buyer the shipping question comes before price: SKO lists international service, Licensed Peptides has no verified destinations. For a US buyer, Licensed Peptides publishes the more detailed carrier terms and SKO publishes the faster stated options.
Buyer profiles: who should pick Licensed Peptides, who should pick SKO
The international buyer: SKO Compounds. It is the only one of the two listed as shipping outside the United States, and it accepts credit/debit card.
The GLP-3R buyer planning to use a code: SKO Compounds. Licensed Peptides is 6% lower before the code at $51.67 per 10mg against $55.00, but PEPTIDEP10 puts SKO at $49.50 against $51.67.
The GLP-2T buyer: Licensed Peptides. It is lower at $46.00 per 10mg against $79.99 before codes, and $46.00 against $71.99 after.
The archive-first buyer: Licensed Peptides. Its 143 report identities, 233 analytical pages and 10/10 COA factor make the larger documentation record, and its 9.5/10 overall score is the higher one. Its Google business profile showed 4.9/5 from 678 reviews, checked October 18, 2026.
The exact-listing buyer: SKO Compounds. 24 of its 34 in-stock listings have an exact issuer-verified certificate, against 4 of 58 at Licensed Peptides.
The price-led buyer with a broad list: SKO Compounds. It is lower on 15 of 23 shared compounds before codes and 17 of 23 after, including GHK-Cu, NAD+, TB-500, KLOW Protocol, GLOW, KPV, Melanotan-1, Melanotan-2, PT-141, IGF-1 LR3, Tesamorelin, Cagrilintide, DSIP, Kisspeptin-10 and Wolverine.
The buyer who wants detailed US carrier terms: Licensed Peptides. It publishes free FedEx 2Day above $200, an $8.95 USPS Ground Advantage rate, a $11.95 paid FedEx 2Day rate and 30-day unopened returns, though the all-sales-final wording conflicts.
SKO's trade-offs are disclosure and policy. It launched in 2026, publishes no street address, named owner or detailed legal-entity information, scores 5/10 on transparency and generally does not accept returns. Licensed Peptides publishes a named owner and contact channels, but its customer accounts include packaging issues and a vial-to-COA strength mismatch, and its all-sales-final wording conflicts with the returns page.
Catalog-only lines: Licensed Peptides alone stocks BPC-157 Spray, BPC-157/TB-500 Spray (Wolverine), CJC-1295 (No DAC), CJC-1295 (With DAC), Dihexa, Epithalon (Epitalon), NAD+ Spray, Oxytocin, PT-141 Spray, Selank Spray and Semax Spray. SKO alone stocks AOD-9604, ARA-290 (Cibinetide), BPC-157, Glutathione, Semax and Thymosin Alpha-1.
