Retatrutide for three months costs £229.00 on the four-month vial pack, £57.25 a month, about as much as I've ever paid, the cheapest route so far. Pens work out higher, from £149.00 for a single two-month pen upward. I chose vials to keep the monthly figure predictable and the parcel simple. What still is not fixed until you decide is which package actually suits a first order, and that took longer to work out than the injections themselves.
I order from EuroPepLabs and have done since my first vial. The batch certificate is in the box and online under the batch number, which is the first thing I check.
My retatrutide cost per month has ranged from £45.75 on the largest vial package to £74.50 for a single pen bought alone. A single 10mg vial is £59.95, and a starter kit with bacteriostatic water, syringes and a dosing card is £69.95, which felt like the smallest possible way to begin before committing further.
Two vials for £119.00 bring the monthly rate to £59.50, four vials for £229.00 drop it to £57.25, and six vials with the free injection kit, discounted from £359.70 to £299.00, work out at £49.83 a month. Twelve vials at £549.00 gave me the lowest monthly rate, £45.75.
The pen side runs differently. A single 40mg pen is £149.00 for about two months, which is £74.50 a month alone. Two pens for £249.00 bring that to £62.25, three pens with the free injection kit at £329.00 come to £54.83, and six pens at £499.00 land at £41.58 a month, the cheapest rate I found across either format. I paid by bank transfer at checkout each time, the only method the shop offers, and it worked without any fuss on every order I placed.
Retatrutide is not licensed by the MHRA, no GP can prescribe it, sold as a research peptide, so the monthly cost comes with no insurance to offset it. Every pound of my three-month spend was mine to plan for, which made the per-month figure matter more than it might with a prescribed medicine.
On the twelve-vial package that meant £45.75 a month, and on the four-month vial pack it was £57.25 a month, the package I actually used for my own first quarter. Neither figure includes anything extra, since delivery is always free and nothing is owed at the door.
The pen route sat higher, at £74.50 a month for a single pen or £62.25 a month across the four-month pen pack. Paying by bank transfer at checkout was the only option either way, and free delivery meant nothing extra landed at the door. Working out these numbers before ordering saved me from assuming a licensed price applied to something the shop is upfront about not being, since there is no NHS or insurance route to soften any of it.

The parcel that covered my first three months held vials from batch APL-R-2608-72, printed at 99.31% purity on the paperwork inside. The number on the label matched the number on the vial itself, which was the first thing I checked before mixing anything.
Delivery arrived the next working day, cold-packed, with tracking sent by email so I knew roughly when to expect the courier at the door. Inside the six-vial box was the free injection kit worth £29.95 that comes with the six and twelve-month protocols: bacteriostatic water, 31G insulin syringes and alcohol swabs, along with a dosing and titration card printed in English. Customs was pre-arranged, so nothing was owed at the door and no charge appeared after the parcel was signed for. Delivery itself is always free, whatever the package chosen. I never opened more than one vial at a time, which meant the 30-day returns policy on unopened products stayed available for the rest of the box if my plans had changed partway through. Both batch numbers, vials at APL-R-2608-72 and pens at APL-RP4-2608-42, sit online under their own purity figures for anyone checking twice.
The smallest way in is a single 10mg vial at £59.95, while the most travel-friendly choice is the pre-filled pen that needs no mixing. For anyone working to a tight monthly budget, the twelve-vial package at £549.00 brings the rate down to £45.75 a month, the lowest figure on the whole page. Per milligram the vial route is cheaper throughout, but the pen's £149.00 single unit means no water, no mixing and nothing to measure out before a flight.
I travelled twice during my first three months and reached for the pen both times, simply because attaching a needle and dialling a dose is quicker than mixing a vial in a hotel bathroom. For anyone new to injecting anything, the pen is the easier format to learn on, even though it costs more per month than the equivalent vial package. Either format ships with a dosing and titration card in English, and both carry their own batch number and purity figure on the label, so checking the parcel against the paperwork takes the same two minutes whichever one arrives at the door.
Week seven was the flattest stretch in my log, three weeks with barely any change despite the money already spent by that point. That was the point where the cost felt hardest to justify, because a monthly figure only feels reasonable when something is visibly happening alongside it.
It passed on its own by week nine, and looking back at the log now, slow weeks sat between faster ones the whole way through rather than forming any pattern I could have predicted in advance.
The hardest part of starting was not the spend at all, it was the wait for the first parcel and then working up to mixing the first vial without overthinking it. Once the routine settled, the monthly figure stopped feeling like a decision I had to make again and again and became closer to a fixed household cost, the same way a phone contract does. Whether the spend is reasonable depends entirely on what someone is comparing it against, and I stopped comparing it to anything once the plateau passed and the log started moving again week by week.
Next time I would commit straight to the twelve-vial package instead of testing with a shorter pack first, since the £45.75 monthly rate only shows up once you commit to the full year. My own log shows no clear reason to break the routine into a cycle, and I have kept mine running without gaps rather than stopping and starting, though that is only what worked for my own weeks, not a rule for anyone else. I take mine at roughly the same point in the day rather than strictly fasted, and nothing in my log points to that mattering much either way.
What I would change is ordering the injection kit alongside the very first vial instead of buying it separately, since it comes free with the six and twelve-month protocols anyway. I would also check the batch number against the paperwork the moment the parcel arrives rather than a few days later, just to close that loop early. The three-month figure itself has not moved much since my first order, but which package I chose to reach it has changed completely over that time.
Is retatrutide sold as a peptide in the UK?
Yes, it is sold as a research peptide rather than a licensed medicine, supplied as a vial of powder to mix or as a ready-to-use pen. No GP prescription is needed to place an order.
Should retatrutide be cycled or run continuously?
There is no fixed rule in my own log either way. I have kept mine running without planned breaks, though that reflects my own routine rather than an instruction that applies to everyone else.
Should retatrutide be taken fasted or after food?
My log shows no obvious difference between the two, so I take mine at a consistent point in the day rather than strictly fasted. The consistency mattered more to me than the exact timing.
When does retatrutide peak after each dose?
I have not measured this myself, since that needs laboratory testing rather than a personal log. The dosing and titration card in the box is what I check instead of guessing at timings.
Where does retatrutide ship from before delivery?
Every order ships from the EU, cold-packed, with tracking sent by email and delivery arriving the next working day. Customs is pre-arranged, so nothing has ever been owed at the door across my orders.

This is experience and research, not medical advice. In the UK retatrutide is not a licensed medicine: it has no MHRA licence and is sold as a research peptide, not for human use. Your GP can advise you, and the Yellow Card scheme takes reports of side effects.
