Sourcing Follistatin-344 in Bulk: An EU Wholesale & White-Label Guide for Resellers

> For research-industry resellers and distributors. Follistatin-344 is a laboratory research reagent, sold for Research Use Only (RUO) — not for human or animal consumption, and not a medicine or supplement. This article is about sourcing and logistics, not usage.

If you distribute research peptides, Follistatin-344 is one of those references where your supply chain matters as much as the molecule. It's a recombinant follistatin isoform studied in myostatin and TGF-β signaling models, and demand from research buyers is steady. The question for a reseller isn't *what it does* — it's how to source it cleanly, at a per-vial cost that leaves margin, without a customs headache. Here's how to think about it.

Buy from stock that's already inside the EU

The single biggest variable in research-peptide sourcing is where the inventory physically sits. Peptworks holds Follistatin-344 in stock inside the EU, so orders move as intra-community shipments: no customs clearance, no import broker, no seized-parcel risk, and typically 3-5 business days to your door. For a reseller, that predictability is the difference between a catalog you can promise on and one you can only hope on.

Bulk unbranded vs. white-label

There are two ways to buy, and they serve different reseller models:

• Bulk unbranded vials — plain vials you slot into your own workflow. Fastest path if you already have your own labeling or you resell to labs that don't need branding.
• White-label — vials labelled with *your* brand and boxed, so the product arrives shelf-ready under your name. A one-time label setup fee of €180 applies under 100 units and is waived from 100 units up.

Either way, the box carries a Peptworks label with a unique QR code that resolves to the exact batch's Certificate of Analysis, independently verifiable through Peptworks. That traceability is a selling point you can pass straight to your own customers.

The per-vial math

Follistatin-344 ships as a 1 mg lyophilized vial. Pricing is public and per-vial, with combined-volume discounts applied to the whole order:

| Combined units | Price / vial | Discount |

|---|---|---|

| 100 | €45.00 | base |

| 300 | €36.90 | -18% |

| 500 | €33.75 | -25% |

| 1000 | €30.60 | -32% |

One detail worth planning around: it's a single tier based on your combined total units, not stacked discounts. Because the discount looks at combined volume across your whole order, the smart move is to consolidate references into one purchase to cross a threshold — a mix of peptides that totals 500 units all price at the -25% tier. The minimum order is 10 units (one box), and vials ship in boxes of 10.

Quality and paperwork your customers will ask about

Every batch is backed by an independent Certificate of Analysis covering ≥98% HPLC purity and heavy metals. That per-batch CoA, reachable by QR and verifiable a petición, is exactly the documentation a research buyer expects — and having it ready shortens your own sales cycle.

Payment is by USDC bank transfer / invoice (no card on site), which suits how most B2B buyers reconcile purchasing. And the Peptworks storefront runs in 10 languages (ES, EN, DE, FR, PT, IT, NL, PL, CS, EL), so a distributor serving multiple EU markets can point customers to a page they can actually read.

Bottom line

For a reseller, Follistatin-344 is a straightforward add to a research catalog *if* the sourcing is right: EU stock for no-customs delivery, transparent per-vial volume pricing, per-batch CoA with QR verification, and a white-label path when you want it under your own brand. Start at the 10-unit minimum to sample the batch, then consolidate to a volume tier once it's moving.

*Research Use Only. Not for human or animal consumption. Not a medicine, supplement, cosmetic or medical device. B2B only.*
