Our Methodology

Russia Peptide Guide is an independent comparison site for research peptide suppliers serving Russia. This page explains how we collect data, calculate scores, manage conflicts of interest, and keep information current.

Important: All products on this site are strictly for scientific research purposes — not for human consumption. We do not endorse, promote, or facilitate the purchase of any product for personal use. Our comparisons are solely for research procurement purposes.

Scoring Criteria

Each supplier receives an editorial score from 0 to 10 based on five equally weighted dimensions. Scores are determined by our research team using publicly verifiable evidence — COAs, Trustpilot reviews, supplier websites, and independent reports.

Testing Standards (20%)

Max: 10/10

Quality and comprehensiveness of Certificate of Analysis (COA) testing. Top scores require independent third-party blind testing across multiple labs covering HPLC, LC-MS, peptide content (CLND), endotoxins (LAL), bioburden (TAMC/TYMC), and heavy metals.

Purity (20%)

Max: 10/10

Stated HPLC purity percentage, verified against COA documentation. Suppliers claiming >99% without independent COA evidence receive lower scores. Scores are penalised if purity claims lack third-party verification.

Russia Shipping (20%)

Max: 10/10

Confirmed delivery to Russia, transit timelines, customs reliability, and documented track record of successful shipments. Highest scores for suppliers with either confirmed domestic production or international shipping to Russia with a reshipping policy.

Value (20%)

Max: 10/10

Price per milligram relative to testing quality. Suppliers offering verified high-quality products at competitive ruble or USD prices score highest. Unusually low prices without testing evidence are penalised.

Trust (20%)

Max: 10/10

Trustpilot score and review count, years of operation, history of public incidents, and community reputation. Serious unresolved incidents result in significant score penalties and a warning flag.

Warning Flags

A warning flag (⚠️) is applied to suppliers with serious unresolved issues that could materially harm Russian researchers. This includes:

Documented widespread delivery failures or non-delivery reports
Fraudulent or fabricated COA documentation
Regulatory actions resulting in product seizures
Customer data breaches without adequate notification

Data Sources

Supplier websites: Pricing, catalogue, sample COAs, shipping policies, and terms of service reviewed directly.

Trustpilot: Scores and review counts manually verified. Only verified reviews are considered.

COA documentation: Sample COAs reviewed to determine whether testing is in-house or third-party, whether labs are named, and whether batch traceability exists.

Community reports: Research communities (Reddit, forums, Discord servers) monitored for emerging delivery or quality issues specific to Russia.

Affiliate Disclosure and Independence

Russia Peptide Guide earns revenue through affiliate commissions when users click our links and make purchases. This is how we fund independent research. Our editorial rankings are determined independently of affiliate relationships:

Scores are calculated before affiliate status is considered
Suppliers without affiliate programs are ranked on their merits regardless of monetisation
All affiliate links use rel="nofollow sponsored" per FTC and Google requirements

We do not accept paid placements, sponsored reviews, or “guaranteed ranking” agreements from suppliers.

Update Schedule

Regular reviews

Supplier scores and data are reviewed quarterly, or immediately after significant events (new supplier launch, documented incident, regulatory change).

Urgent updates

We publish urgent updates within 48–72 hours of a significant event affecting availability or safety for Russian researchers.

New suppliers

New suppliers are considered for inclusion after a minimum of 6 months of operation and at least 30 verified Trustpilot reviews.

Warning flag removal

Warning flags are only removed once the underlying incident has been publicly resolved, verified, and corroborated by reports from affected customers.

About Russia Peptide Guide

Russia Peptide Guide was created to fill a specific gap: no independent peptide supplier comparison site focused on Russia existed. US- and EU-focused sites routinely recommended suppliers without Russia-specific data — confirmed shipping, ruble pricing, or domestic supplier options for Russian labs.

The site is operated by an independent editorial team. We are not affiliated with any individual supplier. All opinions are our own, based on publicly verifiable evidence.
