Looking for a working SLATE Research coupon code? Use Lena at checkout for 20% off your entire order — sitewide, no minimum purchase. We tested this SLATE Research discount code on April 18, 2026, and it applied without issues across their full catalog including BPC-157, GHK-Cu, and GLP-3 Retatrutide.
A 20% sitewide code is unusually generous for a peptide supplier. Most competitors cap their codes at 10-15%, so this is one of the stronger deals we have tracked across peptide vendors in 2026. Below, we break down SLATE Research’s full product line, what each item costs after the discount, and how the pricing compares to other suppliers.

SLATE Research Products and Pricing After Coupon
SLATE Research carries a focused catalog of popular research peptides. Here is what each product costs at sale price and after applying the Lena coupon code for an additional 20% off:
| Product | Original Price | Current Sale Price | After Lena (20% extra off) | Total Savings |
|---|---|---|---|---|
| GHK-Cu | From $50.72 | From $35.00 | From ~$28.00 | ~45% off |
| BPC-157 | From $55.07 | From $38.00 | From ~$30.40 | ~45% off |
| CJC-1295 + Ipamorelin 5+5mg | $85.00 | $56.00 | ~$44.80 | ~47% off |
| GLP-3 Retatrutide | From $92.00 | From $69.00 | From ~$55.20 | ~40% off |
The CJC-1295 + Ipamorelin blend at $44.80 after coupon stands out. This combination peptide typically costs $70-$100 from other suppliers without any discount. BPC-157 starting at $30.40 is also competitive — most vendors price comparable vials between $35 and $55 for similar quantities.
What Is SLATE Research?
SLATE Research is a peptide supplier focused on providing research-grade compounds for laboratory and scientific use. The brand positions itself around four pillars: product purity, third-party testing, quality-controlled manufacturing, and fast shipping.
Every product ships with a Certificate of Analysis (COA) verifying the identity and purity of each compound. SLATE Research states that all peptides undergo independent third-party testing and meet a purity threshold of 99% or higher. This level of testing transparency is an important differentiator in the research peptide market, where not all vendors provide batch-specific documentation.
Their catalog focuses on widely-studied research compounds. BPC-157 is one of the most researched peptides in tissue repair studies. GHK-Cu has been extensively studied for its potential role in wound healing and collagen synthesis. GLP-3 Retatrutide is a newer compound attracting significant research interest. The CJC-1295 + Ipamorelin blend combines two growth-hormone-related peptides commonly used together in research protocols.
All SLATE Research products are sold strictly for research, laboratory, and educational purposes. They are not intended for human consumption.
How SLATE Research Compares to Other Peptide Suppliers
To help researchers evaluate SLATE Research against alternatives, here is a comparison with two other vendors we have reviewed on AllStealDeals:
| Feature | SLATE Research | Qureshi Labs | Ameano Peptides |
|---|---|---|---|
| 3rd-Party COAs | Yes (≥99% purity) | Yes | Yes |
| BPC-157 (starting) | ~$30.40 after coupon | Varies | ~$27 after coupon |

SLATE Research’s 20% coupon code gives it a clear pricing edge over most competitors offering only 10% discounts. On GHK-Cu specifically, the $28.00 post-coupon price is among the lowest we have tracked. For a broader pricing comparison across 9 vendors and 20+ peptides, see our peptide price comparison guide.
SLATE Research Shipping and Quality Assurance
SLATE Research prioritizes shipping speed and package integrity. Each order is inspected before dispatch, and packaging is designed to protect temperature-sensitive peptide compounds during transit.
On the quality side, three elements are worth noting. First, all products include a Certificate of Analysis (COA) for the specific batch shipped, not a generic document. Second, manufacturing takes place in quality-controlled laboratory environments. Third, independent third-party testing verifies purity at 99% or higher for every batch. These quality steps align with what researchers should expect from a credible peptide supplier.
SLATE Research also offers direct support for product selection and technical questions — a practical benefit for researchers working with compounds they have not previously sourced from this vendor.
More Ways to Save at SLATE Research
Stack the coupon with existing sales. Several SLATE Research products are already discounted 25-34% before any code is applied. The Lena code takes an additional 20% off the sale price, pushing total savings above 40% on most items.
Order combination peptides. The CJC-1295 + Ipamorelin blend at $44.80 after coupon costs less than buying each compound separately from most vendors. Blends reduce both per-unit cost and shipping fees.
