Prices for Retatrutide Starter Kit start at £57.99 for the 10mg kit, and all of it is already in British stock at diluents.co.uk rather than sourced to order. It is offered as kit. Order on a weekday before 2pm and the parcel leaves that day, tracked, in a box that gives no clue to its contents.

Because the parcel never leaves the country, nothing has to clear customs, no import charge falls due and nothing is held at a border. Each batch tests at ≥99% by HPLC, and a certificate of analysis for the stock you receive is available on request.

Tracked delivery costs £4.95, or nothing above £75. The ordering steps, one by one.

What is Retatrutide Starter Kit?

Retatrutide Starter Kit is a starter kit made up of Retatrutide 10mg and Bacteriostatic Water 10ml, plus 10 × insulin syringe, 1ml 30g and 10 × alcohol swab. It comes as one main item, boxed with its consumables. The main item is exactly what its own page sells, with nothing altered. The kit's purpose is a first order placed in one checkout rather than three.

What does the box contain?

Every item, at its individual price
ItemPrice alone
Retatrutide 10mg £44.99
Bacteriostatic Water 10ml £5.49
10 × insulin syringe, 1ml 30G£1.00
10 × alcohol swab£0.40

What arrives in the parcel?

Inside the parcel: one main item, boxed with its consumables. Everything in the contents table comes in one box, and the main item is identical to the one sold by itself.

Stacks, blends and kits do not arrive alike: how each one arrives.

Does the set cost less than buying its parts?

Each component at its individual price
ItemPrice on its own
Retatrutide 10mg £44.99
Bacteriostatic Water 10ml £5.49
10 × insulin syringe, 1ml 30G£1.00
10 × alcohol swab£0.40
Total if bought separately£51.88
Retatrutide Starter Kit£57.99

Buying the pieces separately would come to £6.11 less than the box. For that difference you place one order instead of three and get consumables in a sensible quantity, not a hundred-pack of each.

Every item in the table has its own product page, linked above. If you need only part of the set, those pieces can be bought individually.

Has research looked at this combination?

No published work examines Retatrutide Starter Kit as a combination. What evidence exists is for each component individually, and every one of them links to its own page.

Buying Retatrutide Starter Kit in the UK: where and how

How does ordering work?

Choose a strength, add it to the basket and go through checkout; no account is needed. An order confirmation comes through at once, and since the site never takes a card, the payment details arrive separately by email.

What difference does UK stock make?

Your Retatrutide Starter Kit is sent from a warehouse in Britain, so it skips customs, attracts no import charge and loses no days travelling from overseas. A courier collects it the same afternoon if the order is in before 2pm on a working day; the parcel then travels tracked in a plain outer box.

What do you receive?

Purity≥99%, measured by HPLC
LabellingCompound name, strength, format, purity and a research-use statement
Certificate of analysisAvailable on request for the stock you receive
DeliveryUK addresses only, tracked. £4.95, or free over £75
ReturnsWithin 14 days for sealed, unopened items, see the terms

Retatrutide Starter Kit storage

Vial, still sealedKeep it dark, dry and cool; the freezer suits long-term storage best.
After mixingRefrigerate it upright and shaded. A mixed solution should never be frozen.

What is its shelf life?

Typical keeping times for lyophilised peptides in general
ConditionTypical life
Unopened, in a −20 °C freezerYears. No other condition preserves a lyophilised peptide as well
Unopened, in a fridge at 2–8 °CMonths
Unopened, at room temperatureWeeks. It copes with the time in transit but should not be kept like this
Mixed, in the fridgeWeeks rather than months. With bacteriostatic water added, the usual working figure is four weeks, and making that possible is the job of its preservative
Mixed, then frozenNot recommended. Peptides are torn by ice crystals, and each freeze–thaw cycle compounds the damage

These are the standard figures for lyophilised peptides in general; no stability study on a single batch produced them. Time is gained by keeping it cold and dry, and lost to damp, warmth, light and rough handling. A certificate of analysis is available on request.

Here it is supplied strictly as an unlicensed compound for laboratory research use only. No UK marketing authorisation covers Retatrutide Starter Kit and it is not a licensed medicine, nor is it intended for human or veterinary use, or for food.

Compounds of this kind are not controlled drugs, and they can lawfully be sold as laboratory material; it is selling or marketing them for use by people that the law does not allow. That boundary is why this site carries no dose, protocol, route, frequency or medical claim, and why an emailed request for one is declined as well.

Some molecules in this range are also present in a licensed medicine marketed under a brand name. Its authorisation covers only the finished product for which it was granted, not the molecule in any other setting. Read the full terms.

Research use only. Diluent is not a pharmacy, and none of its compounds is a licensed medicine: everything is sold for laboratory research, with no dosage, protocol or administration guidance given. Not intended for human or veterinary use, or for use in food.
