It is the most requested peptide in our range.<\/p>\n<p>Choose 10, 20, 30 or 40 mg per pen. The dial lets you step up gradually without ever drawing from a vial.<\/p>\n<h2>Why a pen instead of a vial<\/h2>\n<p>A vial has to be reconstituted with bacteriostatic water, stored, and drawn up with a syringe each time. The Retatrutide pen skips all of that. The peptide comes already dissolved and sealed inside the cartridge; you set the dial and the pen measures it for you. It is quicker, tidier, easier to travel with, and there is no guesswork about how much is left \u2014 the window shows you.<\/p>\n<h2>What\u2019s in the box<\/h2>\n<ul>\n<li>One Retatrutide pen, in your chosen content (10 mg \/ 20 mg \/ 30 mg \/ 40 mg), pre-filled and sealed<\/li>\n<li>Snap-on cap<\/li>\n<li>A supply of pen needles<\/li>\n<li>Insulated pouch and gel packs (every order ships chilled)<\/li>\n<\/ul>\n<h2>Scan the pen for full instructions<\/h2>\n<p>Every pen has a QR code printed on it. Scan it with your phone and you get the complete step-by-step use guide for Retatrutide \u2014 attaching a needle, priming, setting the dial, storage \u2014 plus the pen calculator, which converts any dial setting into the amount dispensed. No leaflet to lose: the instructions are always on the pen. You can also open it here: <a href=\"\/th\/peptide-pen-instructions\/#retatrutide\">Retatrutide pen guide & calculator<\/a>.<\/p>\n<h2>Using the dial<\/h2>\n<p>Every click on the dial is a fixed step. The window shows the number you have selected; the calculator on the guide page turns that number into milligrams or micrograms for Retatrutide, so you always know what a setting means. Replace the needle after each use and put the cap back on.<\/p>\n<h2>Storage<\/h2>\n<p>Store the pen in the fridge at 2\u20138 \u00b0C, cap on, out of direct light. Do not freeze it. Once in use, keep it refrigerated between uses. Every pen is filled to order in Bangkok, so nothing sits on a shelf.<\/p>\n<h2>Shipped chilled, same-day in Bangkok<\/h2>\n<p>Pens are packed cold: every order goes out in an insulated pouch with gel packs, so the pen stays at fridge temperature from our fridge to your door. Order before <strong>3pm<\/strong> for same-day courier delivery across Bangkok; everywhere else in Thailand ships by tracked express and arrives in 1\u20133 days, chilled the whole way. Pay by cash on delivery in Bangkok, bank transfer, card link, or crypto.<\/p>\n<h2>Prefer a vial?<\/h2>\n<p>Retatrutide is also available as a lyophilised vial: <a href=\"https:\/\/bangkokpeptidecenter.com\/th\/product\/buy-retatrutide-bangkok\/\">Retatrutide 10mg vial<\/a>.<\/p>\n<h2>Questions<\/h2>\n<p>Message us on <a href=\"https:\/\/wa.me\/66661124978\" target=\"_blank\" rel=\"noopener\">WhatsApp<\/a> or LINE (@bkkpeptidecenter), seven days a week.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Retatrutide in a ready-to-use pen \u2014 10 mg \/ 20 mg \/ 30 mg \/ 40 mg pre-filled, sealed, nothing to mix or draw up.
