LabFirst publishes 21 certificates that PeptidePrices matched to the official Kovera originals. Every report names LabFirst and covers an exact advertised vial strength. Its Santa Ana dispatch address, published quality-refund terms and six Google reviews provide additional business evidence. LabFirst earns 8/10; its limited testing coverage and short operating history keep that score below established vendors.
Evidence summary
LabFirst Peptides COAs and evidence
LabFirst earns 8/10 from 21 verified three-panel certificates, clear policies and a small early customer record. Exact certificates cover 21 of 119 comparable strengths. Testing coverage, the absence of extended panels and the short business history determine the remaining gaps.
01
Complete certificate review
PeptidePrices reviewed all 21 lot cards on the LabFirst certificate page on October 6, 2026. All 21 complete vendor PDFs match the corresponding official Kovera originals byte for byte. Every report names LabFirst Peptides as the client and prints Certified September 29, 2026. PeptidePrices completed the independent laboratory comparison on October 6, 2026. All 21 originals and all 21 pages are retained with specific laboratory links, report IDs and access codes. No issuer, client or nominal-strength conflict was found.
02
What the laboratory measured
Every report includes three test types: identity by LC-MS, purity by RP-HPLC and measured content. LC-MS compares the sample’s mass spectrum with the named compound; HPLC separates components and measures chromatographic purity. The measured-content result gives the amount in the tested vial. Purity spans 99.359–99.888%. Total measured content spans 88.3–144.4% of nominal label. The lowest proportion is GLP-3R 10 mg at 8.83 mg; BPC-157 10 mg measures 14.44 mg. Four blend reports give component quantities. The complete Kovera pages contain no endotoxin, microbial, sterility, metals or residual-solvent result.
03
Coverage for current strengths
The finite storefront contains 67 product pages and 126 size variants. After excluding two water sizes and five compounds outside the comparison index, the price catalog has 119 comparable single-vial strengths across 61 compounds; 59 are in stock. All 21 certificates cover exact current strengths and all 21 are in stock. The other 98 comparable strengths have no published matching certificate. Blend strength uses the stated total per vial. Catalog pages show size-level stock; the storefront’s older 74-product availability statement is not used for these counts. The filtered report library retains all 21 certificates.
04
Customer reviews and business history
The vendor-linked Google business profile shows 5.0/5 from six reviews on October 6, 2026. We read all six; comments describe delivery, packaging, waitlist updates and helpful service. They remain external customer accounts. The live Trustpilot profile shows zero reviews. A cached regional profile displaying one review and 3.7/5 is preserved as historical indexed evidence and supplies no current aggregate rating. The authoritative domain record dates registration to August 25, 2026. LabFirst publishes dispatch from 1403 N Tustin Ave, Santa Ana, California 92705. Its exact operating legal entity and founding date were not independently confirmed.
05
US shipping and payment
The shipping policy lists same-business-day dispatch for orders before noon Pacific, otherwise the next business day. USPS Ground is estimated at 2–5 business days, Priority at 1–3 and Express overnight to most addresses. Ground is free for orders over $150 after discounts and costs $15 below that threshold. Priority uses the USPS ZIP quote plus $5, with an $18 minimum. Checkout confirms United States shipping and Zelle, Cash App or Venmo payment. No credit-card option appears. Use PEPTIDEPRICES for 10% off merchandise.
06
Returns and quality remedies
The return policy makes orders final sale except specified remedies. Wrong products, damaged vials or lot mismatch reported with photos within 72 hours receive replacement or refund, including shipping. Cancellation is available until a tracking number is issued. An independent laboratory result showing wrong identity, purity below 99% or net content below 85% of label qualifies for a full vial refund, without a time limit or return requirement.
