Crush Research Supply Company is a US-based research peptide vendor founded by veteran Rory (Peptok) in 2025. Based in Canoga Park, California, the company holds a 4.9/5 rating from 36 independent reviews and a 9.59/10 score on PeptideBenchmark. It’s one of the more documented mid-tier domestic suppliers available.
Every batch undergoes HPLC purity analysis, endotoxin screening, and third-party lab verification before sale. The catalog covers approximately 11 peptides. GLP-1 compounds like Tirzepatide and CJC1295/Ipamorelin are among the most-stocked. Pricing sits at roughly $35 (USD) per vial in 10-Pack bundles, with free shipping on orders over $200 (USD).
This review covers testing practices, catalog depth, pricing, shipping, complaints, and comparisons to Elite Biogenix and Peptide Partners. One detail shapes every recommendation: Crush Research changed ownership on August 31, 2026, and the track record under the new operator is not yet established.
What Is Crush Research Supply Company?
Crush Research Supply Company is a US-based research peptide supplier founded by veteran Rory (known online as Peptok), built on transparency, fast shipping, and competitive pricing. Here’s the thing: the company launched after Rory spent years publicly calling out overpriced, poorly tested peptides. That frustration turned into a real business.
Rory started Crush Research to prove a better standard was possible. Every question and email gets answered personally. The company doesn’t aim to be the largest peptide vendor, but transparency and price-to-quality ratio are its core identity.
Crush Research also operates a skincare line called Beauty Crush, which uses biomimetic peptides including Palmitoyl Tripeptide-1, Palmitoyl Tripeptide-5, and Palmitoyl Tetrapeptide-7. The skincare side targets visible signs of aging through collagen and extracellular-matrix support.
Crush Research at a Glance:
| Detail | Info |
|---|---|
| Founded | 2025 |
| Location | Canoga Park, California, USA |
| Ownership | Veteran-founded; sold to new owner August 31, 2026 |
| Community Rating | 4.9/5 (36 reviews, Peptide Critic) |
| Benchmark Score | 9.59/10 (PeptideBenchmark) |
Who Founded Crush Research?
Rory, the co-owner, built Crush Research after establishing a social media following as Peptok, where he publicly criticized overpriced peptides and poor testing standards in the research market. His founding premise was simple: the industry needed a vendor willing to prioritize testing and price over profit margin.
The company launched in 2025 and is based in Canoga Park, California, USA. From day one, Rory handled customer support personally. That direct approach became one of the brand’s most recognized strengths in its short time operating.
Is Crush Research Veteran Owned?
Yes. Crush Research Supply Company was founded by a veteran and markets itself as veteran-owned, with that designation prominently displayed on its homepage. The veteran identity is part of the brand’s integrity pitch, not just a marketing label.
Here’s what you need to know: Crush Research was sold to a new owner on August 31, 2026. The veteran-owned origin story applies to the original founder, not the current operator. Researchers considering this brand should factor in that ownership change when evaluating trust signals.
What Peptides Does Crush Research Sell?
Crush Research sells approximately 11 research peptides focused on GLP-1 compounds and tissue repair, positioned as a domestic US alternative to international suppliers. The catalog is smaller than marketplace platforms, but it covers the most-searched peptide categories for researchers.
In fact, documented products include CJC1295/Ipamorelin kits, Cagrilintide, and Tirzepatide. Multi-vial packs are available. 10-Pack bundles are priced at $350.10 (USD), down from $389.00. The per-vial cost drops to approximately $35 (USD).
The good news? The core GLP-1 lineup is well-covered. But regenerative compounds like GHK-Cu aren’t part of the current catalog. Researchers needing a broader range may need to supplement orders with a secondary supplier.
Catalog Gaps to Know:
- GHK-Cu (regenerative copper peptide) not available
- Approximately 11 peptides vs dozens on marketplace platforms
- Stock availability inconsistent with regular ‘low stock’ notices
- No GHK-Cu despite active researcher demand in 2026
How Many Peptides Are in the Crush Research Catalog?
Crush Research carries approximately 11 peptides, a focused catalog that prioritizes depth of testing over breadth of selection. Stock availability is inconsistent. That matters. Regular ‘low stock’ notices appear on the site, so plan purchases in advance.
10-Pack bundles are offered at $350.10 (USD), down from $389.00. At roughly $35 (USD) per vial, bulk orders bring the per-unit cost in line with competitive mid-tier US vendors.
Does Crush Research Sell GLP-1 Peptides?
Yes. Crush Research carries GLP-1 peptides including CJC1295/Ipamorelin and Tirzepatide, two of the most-researched compounds in the current peptide market. These are among the most consistently stocked items in the catalog.
All products are sold strictly for research purposes only. The company’s FDA disclaimer makes clear that none of these products are intended to diagnose, treat, cure, or prevent any disease.
How Does Crush Research Test Its Peptides?
Crush Research subjects every batch to HPLC purity analysis, independent third-party lab testing, and endotoxin screening before listing the product for sale. To put it simply: the published testing index as of September 30 contains 194 listed results, with 167 complete certificate PDFs available publicly.
The 99.5%+ purity standard is verified by independent labs, not self-reported. Batch-level Certificates of Analysis are published on the Testing Results page. Researchers can inspect results before purchasing. That’s a level of transparency most mid-tier vendors skip.
Bottom line: 144 of 167 complete certificate PDFs check out at the issuing laboratory under the Crush Research name and exact lot number. Most certificates come from ILS Laboratories, with additional results from Freedom Diagnostics and Vanguard Laboratory.
Testing Process Steps:
- Batch received and assigned a unique lot number
- Sample submitted to independent third-party laboratory
- HPLC purity analysis run to confirm 99.5%+ purity
- Endotoxin screening completed to meet research safety thresholds
- Certificate of Analysis issued by lab and published on the Testing Results page
- Product listed for sale only after all tests pass
Does Crush Research Use Third-Party Lab Testing?
Yes. Crush Research uses a network of independent labs including ILS Laboratories, Freedom Diagnostics, Vanguard Laboratory, and BTLabs for all batch-level testing. Here’s what makes this stand out: researchers can leave the Crush Research website and inspect certificates directly on the ILS Laboratories domain without creating an account.
144 of 167 complete certificate PDFs were verified at their issuing lab under the Crush Research name and exact lot number. For 22 additional preview sets where Crush doesn’t host the complete PDF, ILS Laboratories provides the full certificate independently.
Testing Partners:
- ILS Laboratories (primary; most certificates hosted here)
- Freedom Diagnostics
- Vanguard Laboratory
- BTLabs (certificates include Crush Research name and lot number)
What Is a Certificate of Analysis (COA)?
A Certificate of Analysis is a batch-specific document from an independent laboratory confirming the purity, mass, and endotoxin levels of a specific peptide lot before it is sold. Crush Research publishes one for every single batch. The company stands among the more transparent vendors in the domestic US market.
COAs are available on the Crush Research Testing Results page without any login requirement. And it gets better: readers can verify the same document on the external lab’s own website. The two-source verification trail is something most peptide vendors don’t provide.
What Do Crush Research Reviews Say?
Crush Research holds a 4.9/5 community rating from 36 reviews on Peptide Critic and 28 reviews on Trustpilot, with consistent praise for quality, pricing, and customer service. PeptideBenchmark ranks the company at 9.59 out of 10, calling it ‘one of the strongest curated cases on the site.’
Here’s what that means in practice: only 1 of 36 buyer reviews (3%) rates Crush Research at 3 stars or lower. The remaining 97% are positive. Common themes include fast shipping, high-purity testing, and responsive personal service from the founding team.
Pay attention to this: the review record applies to the previous ownership only. Crush Research was sold on August 31, 2026. Peptide Critic has flagged the brand as ‘effectively unreviewed’ under the new operator until an independent post-sale track record is established.
Review Sources:
| Platform | Rating | Reviews |
|---|---|---|
| Peptide Critic | 4.9/5 | 36 |
| Trustpilot | Not specified | 28 |
| PeptideBenchmark | 9.59/10 | Curated score |
What Are the Positive Crush Research Reviews?
Verified buyers consistently cite ‘tested high-quality peptides with excellent pricing’ as the defining strength, with multiple reviewers independently naming it the most trustworthy domestic US supplier recommended by a top peptide expert. One reviewer placed 4-5 orders and confirmed 1-2 day shipping every single time.
Customer service is a recurring theme. The founder personally resolved a flash sale order glitch for one customer, honoring the sale price after a system error. Questions and emails receive personal responses within hours, not days. That’s rare at this price point.
Are There Any Complaints About Crush Research?
Yes. Crush Research has a small but documented complaint record, with the most notable issue being a Visa credit card payment processed through an international merchant and charged in Mexican pesos in August 2026. The buyer had no advance notice of the currency conversion.
One researcher reported running a CJC1295/Ipamorelin kit for 11 weeks at 300mcg each with no change in IGF-1 bloodwork from the pre-cycle baseline. This represents 1 of 36 reviews and falls within the 3% negative rate. That said, it’s worth noting.
Here’s the part most people miss: the ownership change on August 31, 2026 is the most significant unresolved concern. Peptide Critic has flagged all previous ratings as applying to the prior operator only, recommending buyers wait for new post-sale reviews before forming conclusions.
How Fast Does Crush Research Ship?
Crush Research ships orders same or next business day from its US facility in Canoga Park, California, giving it a significant speed advantage over international peptide suppliers. Multiple verified buyers confirm arrival within 1-2 days of dispatch. That’s not a marketing claim; that’s a recurring pattern across independent reviews.
Real-time tracking is available on all orders. The domestic fulfillment model eliminates customs delays that affect international vendors. The main risk is stock availability, not shipping speed.
Does Crush Research Offer Free Shipping?
Yes. Crush Research offers free shipping on all orders over $200 (USD), a threshold reached with approximately 6 vials at the standard per-vial pricing. At $35 (USD) per vial in 10-Pack bundles, a single multi-vial order qualifies automatically.
US-based fulfillment means no international fees or customs delays. Inconsistent stock availability is the primary risk for domestic orders, not shipping cost or speed.
How Much Do Crush Research Peptides Cost?
Crush Research prices Tirzepatide 30mg at approximately $55 (USD) per vial, with 10-Pack bundles available at $350.10 (USD), bringing the per-vial cost down to approximately $35 (USD). Pricing sits above the cheapest marketplace options but well below premium US vendors like Elite Biogenix.
Discount codes are available. PEPTIDECRITIC unlocks 10% off at checkout. A birthday sale in August offered 10% off the entire store plus an extra 5% off every 5-Pack. The company describes its prices as ‘among the most competitive in the US research vendor market.’
Pricing Breakdown:
| Product | Price (Single) | Price (10-Pack) | Per Vial |
|---|---|---|---|
| Tirzepatide 30mg | ~$55 (USD) | $350.10 (USD) | ~$35 (USD) |
| Cagrilintide | Not specified | $350.10 (USD) | ~$35 (USD) |
| CJC1295/Ipamorelin kit | Not specified | Not specified | Not specified |
Is Crush Research the Cheapest Peptide Vendor?
No. Crush Research is not the cheapest peptide vendor, with Tirzepatide at $55 (USD) per vial sitting above some marketplace and direct-source options for the same compound. The pricing model prioritizes verified purity over minimum cost.
The value case rests on batch-level COAs and 99.5%+ purity alongside the pricing. Researchers who need the lowest per-vial cost may find better numbers on marketplace platforms, but without the same testing transparency.
Is Crush Research Legit?
Yes. Crush Research is a legitimate mid-tier research peptide vendor with batch-specific lab testing, domestic US shipping, competitive pricing, and one of the strongest public evidence trails in the independent vendor benchmarks. PeptideBenchmark rates it 9.59 out of 10.
The transparency model stands out. 194 public testing results, 167 complete certificate PDFs, and external lab verification accessible without a login. That level of documentation is rare among mid-tier domestic vendors. In fact, PeptideBenchmark calls it ‘one of the strongest curated cases on the site.’
But here’s the kicker: concerns are real. Zelle-only payment offers no buyer protection. The 11-peptide catalog is smaller than competing platforms. Low stock issues suggest capacity constraints. The new ownership as of August 31, 2026 creates a trust gap that hasn’t been resolved by post-sale reviews yet.
Pros:
- 99.5%+ purity standard with batch-level HPLC verification
- 194 public COA results, inspectable on external lab domains
- Same or next-day domestic US shipping from California
- 4.9/5 community rating across 36 verified buyer reviews
- Competitive pricing vs premium domestic vendors
Cons:
- Zelle-only payment offers no buyer protection
- Limited catalog of approximately 11 peptides
- Inconsistent stock availability with regular ‘low stock’ notices
- New ownership as of August 31, 2026 creates unresolved trust gap
Was Crush Research Sold to a New Owner?
Yes. Crush Research was sold to a new owner on August 31, 2026, with all ratings, testing history, and customer experiences from before that date applying exclusively to the prior operation. Peptide Critic officially considers the brand ‘effectively unreviewed’ under the new operator.
The original founder stated publicly that the company wouldn’t be passed to an untrustworthy person. One post-sale reviewer echoed this confidence, stating they planned to continue purchasing based on trust in the founder’s judgment. The track record under the new owner isn’t established yet.
Crush Research vs Competitors: How Does It Compare?
Crush Research occupies a middle-tier position in the domestic US peptide market, priced below Elite Biogenix but above the cheapest marketplace platforms, with testing standards stronger than most vendors at its price point. The comparison depends on which trade-offs matter most for a given research setup.
Against Elite Biogenix, Crush Research wins on price and loses on catalog depth. Elite offers more compounds at higher per-vial cost. Against Peptide Partners, Crush Research loses on payment flexibility and selection breadth. Peptide Partners accepts more payment methods and stocks a wider range.
And here’s what most comparisons skip: against international vendors, Crush Research wins on shipping speed (1-2 days domestic vs 1-2 weeks international) and testing transparency. International options often offer lower pricing but higher customs risk and less verifiable COA documentation.
Vendor Comparison:
| Vendor | Pricing | Catalog Size | Payment | Shipping |
|---|---|---|---|---|
| Crush Research | Mid-tier | ~11 peptides | Zelle only | 1-2 days (US) |
| Elite Biogenix | Premium | Wider | Multiple methods | US domestic |
| Peptide Partners | Competitive | Wide | Multiple methods | US domestic |
| International vendors | Lowest | Widest | Varies | 1-2 weeks |
Is Crush Research Worth It?
Crush Research is worth it for researchers who need fast domestic delivery, batch-verified purity documentation, and competitive pricing on a focused range of GLP-1 and tissue repair peptides. The testing model and public COA trail make it one of the more transparent mid-tier US vendors available.
Researchers needing wider compound selection, credit card payment protection, or certainty about post-sale quality should consider alternatives. Peptide Partners offers more flexibility on payments and selection. Elite Biogenix offers a longer-established track record at a premium price.
Short answer: if you need fast US shipping with verified purity docs and you’re comfortable with Zelle, Crush Research delivers. But the new ownership as of August 31, 2026 is still an unknown. Cautious buyers may prefer to wait for post-sale reviews to accumulate before placing a first order under the new operator.
