Promotions & offer terms

These terms cover every promotion on this site, alongside our Terms & Conditions. Where an offer states its own terms, those apply.

Halloween Treat Basket (1–31 October 2026)

• Every 2 qualifying single vials in one order earn one free treat vial, up to 5 treats per order (buy 10, get 5).
• Treats are chosen from BPC-157 10mg, GHK-Cu 50mg, GHK-Cu 100mg, KPV 10mg, Epithalon 10mg, Melanotan 2 10mg, Ipamorelin 10mg, AHK-Cu 100mg, PT-141 10mg, DSIP 10mg and Sermorelin 5mg, while in stock. They are added to your cart automatically and you can swap each one on the cart page.
• Research kits, kit subscriptions, diluent and bacteriostatic water don’t count toward treats and can’t be chosen as treats.
• Treats can’t be combined with partner or affiliate codes.
• Treats have no cash value and are removed if the vials that earned them are removed. Orders placed after 31 October 2026 don’t earn treats.

First-order free vial

The first-order free vial is paused. Orders placed from 1 October 2026 don’t receive it.

Research kits

• Sealed 10-vial boxes of one compound from one lot.
• Kit prices are permanent and derived from ten times the single-vial price, discounted — most kits by 40%. The exact saving is shown on each kit.
• Kit pricing is the discount: kits don’t combine with codes, gift tiers, member pricing or bulk quotes, and don’t count toward gift, bundle or diluent thresholds.
• Kits ship free at any order value and leave in 1–2 business days.

Bundle pricing

Two qualifying vials get 3% off; three or more get 7% off, across the whole cart. Free items, diluent and kits don’t count and aren’t discounted.

Pre-orders

• An out-of-stock size can be pre-ordered at the same price as in stock.
• A pre-order ships once the next lot passes testing. If it fails, you choose a full refund or the next passing lot.
• Bundle pricing applies to pre-orders too.
• You pay the price shown when you order; it isn’t repriced later.

Free diluent

Every order with a qualifying subtotal of $100 or more gets a free Molecula Diluent. Kits don’t count toward it.

Free shipping

Orders of $75 or more within the US ship free. The threshold uses listed prices before bundle discounts or codes; free items don’t count. Kits ship free at any value.

Kit Subscription

• 3 to 10 vials in any mix. Your rate is set by two ladders — vials in the kit and number of different compounds — and the lower of the two applies. Two sizes of one peptide count as one compound.

• Paying 3, 6 or 12 months ahead adds 2%, 4% or 6%. No total discount exceeds 36%.
• Nothing recurs automatically and no card is stored. Each shipment is an order you place, rebuilt in one click at the rate you hold.
• Your starting rate holds while the subscription runs. If the ladders improve, you get the better rate.
• Each reorder is priced at current catalogue prices. A compound no longer available is dropped and you are told, never substituted.
• Subscription pricing doesn’t combine with kit pricing, codes, gift tiers, member pricing or bulk quotes. Unsent prepaid shipments are refundable at the price paid.

Refer a friend

• Share your link from your account. When someone new places a first order of $50 or more through it, you get $15 store credit.
• You need at least one order of your own for your link to pay out.
• Credit is a code tied to your account email, valid 90 days, store credit only.
• Credit is withdrawn if the referred order is cancelled or refunded. Self-referrals, duplicate accounts and orders to the same address don’t qualify.

General

We may end or change any promotion at any time; orders already placed keep the terms they were placed under. Offers have no cash value, can’t be exchanged, transferred or applied to a completed order, and may be withheld where we identify abuse.
