Strate Labs Review: Janoshik COAs Meet a Federal Cease and Desist

Strate Labs is one of the more polarizing vendors in the research peptide space. On one hand, they publish third-party Janoshik COAs with purity numbers above 99%. On the other, the U.S. International Trade Commission issued a Cease and Desist Order against them in April 2025 for tirzepatide false designation of origin. That combination of legitimate lab verification and federal enforcement action makes this a vendor that requires careful evaluation.

We scored every vendor in our directory using the same five-signal methodology. Our Strate Labs review lands at a Grade B (3.5 out of 5). That grade reflects real lab verification paired with serious legal and transparency gaps that cap the score. The vendor now operates from stratelabs.is after migrating from the original .com domain the same month the ITC order dropped.

Here is what we found.

Full scoring criteria are documented in our methodology. The editorial cap on this review stems from the ITC enforcement action detailed below.

Strate Labs uses Janoshik Analytical, a Prague-based testing lab, for third-party purity analysis. Janoshik runs HPLC with UV detection as the primary method, supplemented by LC-MS/MS for identity confirmation and GC-MS for contamination screening. This is the same lab used by several other vendors in our directory, including some higher-graded ones.

The published numbers are solid. BPC-157 (Batch 241, July 2024) tested at 99.244% purity with 5.18mg average mass against a 5mg label. Semaglutide (same batch) hit 99.152% at 6.12mg average mass on a 4mg label. Retatrutide tested at 99.43% with 11.15mg on a 10mg label. All three show slight overages, which is favorable for researchers getting more compound per vial than the label promises.

The problem is coverage. Strate Labs lists 55+ peptide SKUs, but only two products appear on the dedicated lab-results page. Individual product pages may link to COAs, but a centralized batch history across the full catalog does not exist. For a vendor selling this many compounds, that gap is significant. We want to see batch-level results for the majority of active SKUs, not just a handful of flagship products.

Their FAQ page lists an expansive testing menu: NMR, FTIR, HPLC, LC-MS, GC-MS, TLC, ICP-MS, gravimetry, UV-Vis, titration, melting point, and organoleptics. The lab-results page only shows Janoshik HPLC data for two products. The gap between claimed testing breadth and published evidence is wide.

Janoshik is widely used in this market but carries limitations worth understanding. The lab is not ISO 17025 accredited, which means results cannot be submitted to regulatory bodies like the FDA. Raw chromatographic data sits behind a paywall on Janoshik’s platform, limiting independent verification. Janoshik also experienced a data breach in February 2026 that exposed customer shipping information for vendors using their services.

None of this invalidates the purity numbers, but it contextualizes them. A named lab is not the same as an accredited lab.

This is the section that sets Strate Labs apart from most vendors we review. Federal enforcement actions against research peptide vendors are uncommon enough that they warrant a full breakdown.

In November 2023, Eli Lilly filed a complaint with the U.S. International Trade Commission alleging that several vendors, including Strate Labs, were selling tirzepatide products under false designation of origin. Tirzepatide is the active compound in Lilly’s Mounjaro brand, and Lilly holds the patents.

Strate Labs did not mount a defense. The ITC found them in default on May 15, 2024. An Administrative Law Judge granted Lilly’s motion for summary determination on the false designation claim in December 2024. The Commission voted not to review that decision in January 2025. Lilly withdrew its remaining claims the same month, but the enforcement action proceeded.

The ITC issued both a Cease and Desist Order and a Limited Exclusion Order against Strate Labs in April 2025. The CDO prohibits importing or selling tirzepatide products. The LEO blocks tirzepatide shipments at U.S. Customs. Tirzepatide has since been removed from the Strate Labs catalog.

Semaglutide and retatrutide remain available as of March 2026. Semaglutide faces its own evolving regulatory landscape, and retatrutide sits in a similar GLP-1 agonist class. The broader enforcement climate makes long-term availability of these compounds uncertain for any vendor.

The timing of the domain migration stands out. Strate Labs registered stratelabs.is on April 1, 2025, the same month the CDO dropped. The original .com domain now redirects to the .is (Iceland TLD) site. Whether this was a direct response to enforcement or coincidental timing, the optics are poor. Vendors that change domains under enforcement pressure create a pattern that undercuts trust, regardless of the operational reason.

This investigation is documented in the Federal Register (Investigation No. 337-TA-1377). It does not mean every product Strate Labs sells is compromised. But it does mean this vendor faced federal enforcement action, chose not to defend itself, and changed domains immediately after. That pattern warrants a scoring cap in our methodology.

Strate Labs carries a broader catalog than most pure peptide vendors. The 88-product lineup spans injectable peptides, SARMs, capsules, liquids, ancillaries, topicals, and spray kits. Unique offerings include the Rhino Rub, a topical BPC-157/TB-500 blend marketed for joint application, and pre-made peptide blends that reduce ordering complexity for common stacks.

Here is how key peptides are priced:

Bulk tiered discounts apply to several products. Retatrutide drops 10% at 4-6 units and up to 30% at 31+ units. A 10-pack runs $1,100 ($110 per vial). BPC-157 scales from $34.95 for a single 5mg vial up to $499.95 for bulk quantities.

The breadth cuts both ways. Researchers focused strictly on peptides may prefer a vendor that specializes rather than one selling SARMs and capsules alongside injectables. A mixed catalog can signal a business optimized for revenue breadth over peptide-specific expertise. For those who want one supplier across multiple compound categories, the selection is extensive.

Strate Labs fulfills US orders from warehouses in Texas and Delaware, shipping from whichever facility is closer to the destination. Orders over $100 qualify for free USPS First Class delivery (2-8 business days). Shipping insurance is required on all orders.

Packaging is nondescript with no markings indicating contents. Product labels can be removed on request at checkout. APO, FPO, and DPO military addresses are accepted. The FAQ confirms acceptance of AA (Americas), AE (Europe), and AP (Pacific) designations for military personnel stationed overseas.

The return policy is where things tighten. All sales are final with no standard refunds or exchanges. The only exception is a replacement for items damaged during transit, and you need to provide proof of damage.

Order cancellations are accepted within a one-hour window after placement. After that window or after shipment, no cancellation is possible. One hour is unusually tight. Most vendors in this space offer at least 24 hours or until the order enters fulfillment. Combined with the all-sales-final stance, this puts the full risk on the buyer from almost the moment of purchase.

Canadian orders route through stratelabs.ca, with Interac e-Transfer as the only payment method. Peptide Protocol Wiki scored Strate Labs 3.0 out of 10 on payment flexibility, the lowest sub-score in their evaluation.

Strate Labs BV operates from Spoorstraat 11b, Doetinchem, Gelderland 7003 DX, Netherlands. The US entity is registered at 8 The Green #6999, Dover, DE. That is a registered agent address used by thousands of companies, not an operational facility.

Three team members appear on the About Us page: Allan Reyes (Head of Product Development), Samantha Wood (Laboratory Technician), and Mark Anthony (Quality Control Manager). No credentials, professional backgrounds, or LinkedIn profiles accompany these names. The actual owner or founder of Strate Labs is not disclosed anywhere on the site. For a company handling research compounds, anonymous ownership is a meaningful transparency gap.

The company claims “10+ years” of operation. The BBB file was opened in January 2023, and the .is domain was registered in April 2025. Neither data point supports a decade of operation under this brand. The claim appears on marketing materials but cannot be independently verified from any public record we found.

The BBB rates Strate Labs a C, specifically for failing to respond to one complaint. The business is not BBB Accredited. ScamAdviser gives the .is domain a 64 out of 100 trust score, flagging the recent registration and low traffic. The SSL certificate is domain-validated only, confirming domain ownership but not business identity.

Running multiple domains (.is for US, .ca for Canada, .com redirecting) is not inherently suspicious. But combined with undisclosed ownership, an unverifiable longevity claim, and a federal enforcement action, the transparency picture is weak. Vendors like Skye Peptides and Simple Peptides in our directory offer significantly more ownership clarity for researchers who prioritize knowing who is behind their supplier.

Independent review data for Strate Labs is thin. Peptide Protocol Wiki rates the vendor 5.3 out of 10 overall, with community reputation scoring just 4.0 out of 10, the lowest category in their evaluation. Knoji shows 2.6 stars from 64 reviews. A separate aggregator reported 3.8 out of 5 from the same review pool, suggesting different weighting methodologies.

There is no Trustpilot page for the peptide business. A “Strats Labs” result on Trustpilot belongs to an unrelated company, which creates confusion for researchers trying to find independent reviews. Peptides.SO lists Strate Labs as unverified with zero reviews as of March 2026.

Community reports suggest fast shipping and professional packaging. One aggregated review described Strate Labs as having “the most professional and speediest ordering and packaging” compared to other sources, with the reviewer noting that product efficacy matched expectations.

The TikTok presence is heavy, but context matters. Strate Labs runs a 15% commission ambassador program that requires an Instagram handle to apply. Top performers receive higher commission tiers and free product. Most TikTok testimonials we reviewed were linked to affiliate discount codes. That does not make the reported experiences false, but the financial incentive is baked in. When the majority of visible testimonials come from affiliates earning 15% per sale, the signal-to-noise ratio drops.

Independent, non-affiliated reviews on established platforms like Trustpilot or the BBB are largely absent. For a vendor that claims over a decade of operation, that gap is notable.

Grade B. 3.5 out of 5.

The Janoshik COAs are real, publicly linked, and show purity numbers above 99% on the products tested. The batch overages are a net positive. US fulfillment from two domestic warehouses means fast shipping. The catalog is among the broadest in the space.

But the ITC Cease and Desist Order is a federal enforcement action on the public record. Strate Labs chose not to defend the case, hopped domains the same month the CDO dropped, and has not publicly addressed the investigation. Ownership remains opaque. COA coverage across the catalog is thin relative to the number of SKUs. The return policy gives buyers almost no recourse.

Strate Labs can work for researchers who verify individual batch COAs before ordering, accept the no-refund terms, and understand the legal history. For those who want vendors with cleaner records and stronger transparency, our vendor directory has alternatives worth considering.

Is Strate Labs legit?

Partially. They publish real third-party COAs via Janoshik Analytical with purity numbers above 99%. They operate US fulfillment warehouses and have years of market presence. However, the ITC issued a Cease and Desist Order against them in April 2025 for tirzepatide false designation of origin. They also carry a BBB C rating for ignoring a complaint and disclose no ownership information. We rate them Grade B (3.5/5).

What happened with the Strate Labs ITC investigation?

Eli Lilly filed a complaint in November 2023 alleging false designation of origin for tirzepatide (Investigation No. 337-TA-1377). Strate Labs did not defend itself and the ITC found them in default in May 2024. The Commission issued a Cease and Desist Order and Limited Exclusion Order in April 2025, prohibiting importation and sale of tirzepatide products. Tirzepatide has been removed from the Strate Labs catalog.

Why did Strate Labs change from .com to .is?

Strate Labs registered the .is domain on April 1, 2025, the same month the ITC CDO was issued. The original .com domain now redirects to stratelabs.is. The company has not publicly explained the migration. A separate .ca domain serves Canadian customers with Interac e-Transfer payments.

Does Strate Labs still sell tirzepatide?

No. Tirzepatide was removed following the ITC Cease and Desist Order in April 2025. Other GLP-1 peptides, including semaglutide and retatrutide, remain available as of March 2026. The broader GLP-1 enforcement climate makes the long-term availability of these compounds uncertain.

What is Strate Labs’ return policy?

All sales are final with no standard refunds or exchanges. The only exception is a replacement for transit-damaged items, which requires proof of damage. Orders can be cancelled within one hour of placement. After that window or after shipment, no cancellation is possible. This is tighter than most vendors in the space.
