Research Peptide RFQ Template 2026: The Document Procurement Teams Should Send

B2B Sourcing | 2026-07-09 | 11 min read

A field-tested RFQ template for research peptides, covering specification sheet, vendor qualification, COA scope, MOQ, lead time, payment terms, packaging, and the comparison matrix procurement teams should use to score quotes.

Why a generic RFQ is the most common procurement mistake

A research peptide RFQ that says "5mg tirzepatide, 98% purity, ship to Boston" forces every supplier to fill the gaps with their own assumptions. The result: three different quotes covering three different scopes, none directly comparable. The fix is a specification sheet detailed enough that interpretation is impossible.

The nine sections every peptide RFQ must contain

A reliable RFQ template has nine sections. Skipping any one of them guarantees downstream friction.

  • **Compound identification** — common name, sequence, CAS, salt form, target catalog SKU
  • **Quality specification** — purity threshold, identity method, endotoxin limit, residual solvent panel
  • **Documentation** — COA scope, chromatogram, mass spectrum, third-party counter-verification
  • **Packaging** — vial size, lyophilized vs. solution, septum cap, label customization
  • **Quantity** — vial count, total peptide mass, MOQ tolerance, forecast horizon
  • **Logistics** — destination country, transit duration, cold-chain band, customs documentation
  • **Lead time** — desired first delivery date, schedule for subsequent releases
  • **Commercial** — payment terms, currency, incoterms, dispute resolution
  • **Compliance** — research-use-only declaration, import permit, regulatory posture

Section 1 — Compound identification

A reliable compound specification includes:

  • International nonproprietary name (INN) or common name
  • Amino acid sequence in single-letter code
  • CAS number when available
  • Salt form (acetate, trifluoroacetate, free base, hydrochloride)
  • Counterion ratio if relevant
  • Reference to a target catalog SKU

Without a CAS or sequence identifier, the supplier is left to guess which form you mean. Tirzepatide, for example, has at least three commercial forms with different counterion profiles. The RFQ must specify which.

Section 2 — Quality specification

The quality section should leave no room for interpretation:

  • Purity threshold (e.g., ≥99% by HPLC at 220nm)
  • Identity method (mass spec expected mass error < 10 ppm)
  • Endotoxin limit (e.g., < 1.0 EU/mg for general research)
  • Microbial limits if relevant (e.g., < 100 CFU/g for cell culture)
  • Residual solvent panel against ICH Q3C limits
  • Visual description target (white to off-white lyophilized powder)

A supplier that cannot meet every line in this section should say so on the quote, not in a follow-up email.

Section 3 — Documentation

The documentation section defines what the COA must contain:

  • HPLC chromatogram with method parameters
  • Mass spectrum with observed vs. theoretical m/z
  • Endotoxin result with method (LAL or rFC)
  • Residual solvent panel
  • Lot number, batch size, and analyst sign-off
  • Storage condition and retest interval

If you need third-party counter-verification, declare it here. Adding it later means paying rush fees.

Section 4 — Packaging

Packaging specification should cover:

  • Vial size (typically 2mL, 5mL, or 10mL crimp-top)
  • Closure type (septum cap, screw cap, crimp seal)
  • Lyophilized vs. solution-phase
  • Label format (one-line, multi-line, custom)
  • Outer box and insert card if required
  • Security seal expectations

Section 5 — Quantity and forecast

Quantity specification should distinguish:

  • Pilot quantity (5-10 vials for qualification)
  • Initial production order
  • 6 or 12-month rolling forecast
  • Acceptable MOQ tolerance (typically +/- 10%)

A forecast commitment in the RFQ is the single highest-leverage negotiating tool. Without it, the supplier cannot offer the deepest tier discount.

Section 6 — Logistics

Logistics specification must include:

  • Destination country and city
  • Recipient entity and end-user laboratory
  • Preferred carrier or incoterm
  • Cold-chain band (ambient, 2-8°C, or -20°C)
  • Transit duration target and maximum
  • Customs documentation requirements

For international shipments, also declare whether the buyer is responsible for import clearance or whether the supplier should use DDP (delivered duty paid) terms.

Section 7 — Lead time

Lead time specification should distinguish:

  • Catalog SKU lead time (in-stock vs. made-to-order)
  • Custom synthesis lead time
  • Sample or pilot order lead time
  • Bulk production lead time
  • Maximum acceptable delay tolerance

Realistic lead time expectations for research peptides: 7-21 days for catalog SKUs, 25-45 days for custom synthesis. Anything shorter usually means a different supplier batched the order at the expense of the next researcher's lead time.

Section 8 — Commercial terms

Commercial terms to fix in the RFQ include:

  • Currency (USD, EUR, GBP, CNY)
  • Payment terms (T/T in advance, 30% deposit + 70% before shipment, Net 30 for accounts in good standing)
  • Incoterms (EXW, FOB, CIF, DDP)
  • Price validity period
  • Force majeure handling

Do not let the supplier default these. Each is a negotiable lever.

Section 9 — Compliance

Compliance specification is the one section most RFQs underweight. Cover:

  • Research-use-only declaration
  • Import permit (if destination country requires)
  • Regulatory posture for the destination market
  • COA retention obligation
  • Audit right (especially for institutional programs)

Scoring matrix: comparing the quotes you get back

Score every quote against the same matrix:

| Criterion | Weight | Score 1-5 | | --- | --- | --- | | Unit price at target quantity | 25% | | | COA scope and documentation depth | 25% | | | Lead time confidence | 15% | | | Cold-chain logistics record | 15% | | | Regulatory and import readiness | 10% | | | Account management responsiveness | 10% | | | Total weighted score | 100% | |

The score total gives you a defensible comparison when leadership asks why you chose supplier A over supplier B.

Common RFQ mistakes that hurt buyers

  • Specifying only purity and vial count
  • Accepting supplier-default packaging without testing
  • Treating "research-use-only" as a marketing line instead of a compliance deliverable
  • Negotiating price without committing to a forecast
  • Skipping the pilot order because the supplier is "well known"
  • Accepting a single COA line ("purity 99%") without chromatogram

How ZePeptide responds to RFQs

A ZePeptide RFQ response includes:

  • Per-SKU quote with tier pricing at the requested volume
  • Lead time confirmation by SKU
  • COA scope confirmation with chromatogram and mass spec included
  • Cold-chain band and packaging validation summary
  • Payment terms aligned to the buyer's commercial section
  • Regulatory posture confirmation for the destination country
  • Pilot order recommendation if the program is qualification-stage

We respond to RFQs within one business day. Use the section structure above to keep the first round of questions focused on price, scope, and lead time rather than clarification.
