Direct answer

Is Y&P Labs legit?

Yes. Y&P Labs has seventeen complete Freedom Diagnostics reports that match specific official laboratory PDFs and name the vendor as client. They report LC-MS identity, HPLC-UV purity and measured content, with dates from May 17 through September 13, 2026. Sixteen current reports cover all 15 of 15 available reviewed product-and-strength listings; the remaining report is an older Retatrutide batch. Both currently shipping 10mg YNP3RT lots are inspectable, and Selank is correctly listed as 11mg despite its SLK10 lot name. The strongest evidence is the complete core-panel archive. Some submitted samples measured below their nominal quantity, including one 10mg Retatrutide sample at 9.78mg and GLOW 70mg components totaling 66.37mg. The documents do not include contamination panels. IGF-1 LR3 is backordered and its certificate is pending; the BPC-157/TB-500 blend also awaits testing. Independent customer feedback remains limited in the reviewed sources. Published shipping includes tracking, insurance and free US standard shipping over $50, while sales are final. Code PEPTIDEPRICES gives 10% off. The overall rating is 8/10.

Evidence summary

Y&P Labs COAs and evidence

Y&P Labs is a strong option for researchers prioritizing identifiable batch documents and clear product prices. Seventeen Freedom Diagnostics certificates match complete official records, and all 15 of 15 available reviewed listings have exact current evidence. The owner-set 8/10 score reflects that core testing strength, published business details and practical shipping terms. Review the lot-specific content values: one current 10mg Retatrutide sample measures 9.78mg, the 20mg sample 19.72mg, and GLOW components total 66.37mg against a 70mg label. The reports lack additional contamination panels, and independent customer evidence is limited. Sales are final with shipping replacements. Use PEPTIDEPRICES for 10% off and compare the delivered total.

01

Complete archive and official laboratory matches

Y&P Labs publishes seventeen complete Freedom Diagnostics certificates dated May 17 through September 13, 2026. Each names Y&P Labs as client, identifies a lot and states the tested product’s nominal amount. PeptidePrices compared the vendor copies with the specific official laboratory PDFs on October 2. Eight copies are byte-identical; the other nine have the same printed fields, chromatograms and mass-confirmation images in differently compressed files. The vendor archive has sixteen issued current reports. A product-page history adds one older Retatrutide certificate. The COA library contains all seventeen issued reports. Two testing-in-progress observations are excluded from certificate totals and library report counts.

02

What the analytical panels cover

All seventeen issued reports include LC-MS identity, HPLC-UV purity and measured net content. Purity ranges from 99.13% for GLOW to 99.95% for CJC-1295/Ipamorelin. These results establish the identity, purity and quantity of the submitted samples. The documents contain no endotoxin, sterility, microbial or heavy-metal panels. Product-page GMP sourcing statements are vendor claims rather than additional tests in these certificates. The owner-set COA quality score is 8.5/10: the complete independently matched core-panel archive is strong, while the analytical scope remains narrower than an archive with documented contamination testing.

03

Lot-specific purity and content results

The two currently shipping 10mg YNP3RT lots have different content measurements. RT10-105 reports 99.87% purity and 10.01mg; RT10-106 reports 99.76% and 9.78mg. September RT20-103 reports 99.82% and 19.72mg for a nominal 20mg sample. GLOW70-103 measures GHK-Cu 47.05mg, BPC-157 10.32mg and Thymosin Beta-4 9.00mg, totaling 66.37mg against the 70mg label. KPV10-103 measures 10.97mg at 99.63% purity. Those report-specific values remain separate from nominal comparison amounts.

04

Current catalog and exact amounts

The catalog spans single compounds and documented blends. All 15 of 15 available reviewed single-vial listings have exact current reports and cover fourteen compounds or blends, including YNP3RT 10mg and 20mg, Tesa 10mg, GHK-Cu 100mg, NAD+ 500mg and Glutathione 1500mg. YNP3RT maps to Retatrutide through its published CAS identity and matching LC-MS report; Tesa maps to Tesamorelin. Selank is an 11mg product even though its lot begins SLK10. Semax’s certificate states a nominal 11mg sample; its 13.90mg measured content is not used as the vial’s nominal amount. IGF-1 LR3 1mg is backordered. The pending BPC-157/TB-500 blend lacks a published nominal amount and stays outside price comparisons.

05

Independent customer reputation

Independent customer reputation is still lightly documented in the sources reviewed on October 2. The exact-domain Trustpilot profile is claimed and showed zero reviews on October 2. Brand searches on Reddit, Finnrick and YouTube did not establish an attributable independent purchase-review or product-testing set. Vendor social accounts and coupon promotions remain separate from customer evidence. No external star average or review count is assigned. The primary domain registration records March 19, 2026; that is the domain’s registration date, rather than proof of the company’s founding date. Laboratory documentation therefore carries more weight than online popularity in this review.

06

Shipping, checkout and returns

The shipping policy lists dispatch within 24 hours Monday–Friday, US standard delivery in two to five business days at $7.99, and free US standard shipping over $50. Expedited options cost $25 or $50. The UK and specified international destinations have separate published rates and free shipping over $250. Tracking and insurance are included. The returns policy makes sales final after ordering, offers replacements for confirmed shipping damage or missing items, and excludes customs holds or seizures. Product pages display card and digital-wallet options alongside Zelle; available methods can depend on the selected destination.

07

Business transparency and overall assessment

The contact page identifies Y&P Labs LLC as a Wyoming LLC, supplies filing ID 2026-001967040 and a Spring, Texas mailing address, and publishes email, telephone and Monday–Saturday support hours. The stated response target is within 24 hours. Those contact and registration details are vendor disclosures; a mailing address does not establish the manufacturing location. Code PEPTIDEPRICES gives a verified 10% discount and cannot be combined with another coupon. Compare the selected lot’s certificate, nominal amount and delivered total when evaluating an order. The owner-set factors produce an overall 8/10 score, balancing the strong core testing archive with limited independent customer evidence and final-sale terms.
