Q: How should Retatrutide Synedica be stored at home?

Before opening: refrigerator 2–8 °C, bottom shelf (not the freezer!). After first use: up to 30 days in a 2–8 °C fridge OR up to 21 days at room temperature (no warmer than +25 °C) — your choice. Protect from direct sunlight. For transport, use a thermobag with a cold pack. If the pen was frozen or heated above +30 °C — discard (the molecule degrades). The expiry date is printed on the box (usually 24 months from manufacture).

Question 1

How much does Retatrutide Synedica 40 mg cost in Ukraine?

Accepted Answer

Price of Retatrutide 40 mg Synedica at DOZA — 15,500 UAH for a syringe pen with 200 units (enough for a full titration course 2 → 12 mg over 20–24 weeks). For comparison: ALLUVI 40 mg costs 18,000 UAH (16% more expensive). Thermobox 2–8 °C delivery is included: Kyiv — 1 day, all of Ukraine — 1–2 days. Payment: 50% prepayment (cold-chain guarantee), 50% on delivery.

Question 2

Synedica or ALLUVI — which should I choose?

Accepted Answer

Both brands contain the same molecule (LY3437943) at pharmaceutical purity. SYNEDICA (Germany) — 20 mg/mL × 2 mL, 200 units, 15,500 UAH. ALLUVI (Switzerland) — 40 mg/mL × 1 mL, 100 units, 18,000 UAH. For most clients we recommend SYNEDICA: a wider pen makes dosing smoother at the start (2 → 4 → 6 mg), and 200 units covers the full titration without needing extra pens. ALLUVI is chosen if Swiss manufacturing is important or there is a phenol allergy (ALLUVI uses a different preservative).

Question 3

How do I verify Retatrutide Synedica authenticity?

Accepted Answer

Four authenticity markers: (1) Synedica Laboratories hologram on the side of the box that shifts colour from green to purple; (2) QR code on the packaging → verify.synedica.com, enter the serial number and get manufacturer confirmation; (3) the serial number always starts with "S" (e.g. S-04-24-XXXX); (4) on receipt, the thermobox is cold (no warmer than +8 °C) with a temperature logger. DOZA sources Retatrutide Synedica directly from the official distributor in Warsaw; on request we send the CoA (Certificate of Analysis) of the specific batch.

Question 4

Is there an official Synedica website in Ukraine?

Accepted Answer

The official manufacturer site is synedica.com (Germany, not UA-zone). In Ukraine, Synedica has no direct online shop — only authorised distributors. DOZA is one of those distributors, working directly with the Berlin factory via an office in Warsaw. Warning: synedica-reta.com, synedica-ua.com, synedica.ua are NOT official Synedica Laboratories resources; as of end-2026 we have identified at least 3 fake landing pages using the brand logo without any physical warehouse. Buying on such sites = risk of counterfeit without cold-chain.

Question 5

What is the starting dose for Retatrutide Synedica 40 mg?

Accepted Answer

Standard protocol (TRIUMPH-1, phase II): start 2 mg once weekly subcutaneously × 4 weeks → 4 mg × 4 weeks → 6 mg × 4 weeks → 8 mg × 4 weeks → 12 mg (maintenance). Full titration 20–24 weeks. 40 mg in the Synedica pen is enough for the whole course for one person. The dose is increased by the DOZA physician individually after monitoring tolerance (nausea, diarrhoea) and weight change. Moving to 15 mg (the trial maximum) is only decided after 24 weeks on 12 mg.

Question 6

Where to buy Retatrutide Synedica in Kyiv and across Ukraine?

Accepted Answer

At DOZA — a specialised GLP-1 therapy clinic. Kyiv: courier delivery in a 2–8 °C thermobox, 1 day. Ukraine: Nova Poshta in a thermobox with a temperature logger, 1–2 days. Pickup in Kyiv — by prior arrangement. Place an order: product page → "Buy" or via Telegram bot @Doza_sofiia_bot (will suggest the starting dose, protocols and answer questions). Your physician will be notified, contact you to clarify your history and decide whether to start titration.

Question 7

How does Synedica differ from Retatrutide by Lilly?

Accepted Answer

Lilly (originator of LY3437943) has not yet released Retatrutide commercially — only phase III (TRIUMPH-4, completion 2027). Only peptide-grade analogues are available as research-grade pens from specialised manufacturers (Synedica, ALLUVI, Pen Peptide). The molecule is identical (LY3437943 = Retatrutide), purity is pharmaceutical-grade (>98% HPLC). When Lilly registers commercial Retatrutide in the EU (expected 2028), DOZA will be first to bring it to Ukraine. For now, Synedica is the closest to the future Lilly brand in quality and documentation.

Question 8

Can Retatrutide Synedica be combined with other GLP-1s?

Accepted Answer

No. Retatrutide is a triple GLP-1/GIP/glucagon agonist; combining with Ozempic/Wegovy (semaglutide) or Mounjaro (tirzepatide) would overdose GLP-1 receptors and cause severe side effects (24/7 nausea, pancreatitis risk). Switching: finish the previous drug, wait 7 days washout, start Retatrutide at 2 mg. If you are already on Mounjaro 15 mg — the DOZA physician will adjust the starting Retatrutide dose (you can start at 4 mg instead of 2 mg, as the body is adapted to triagonism).

Question 9

What are the side effects of Retatrutide Synedica?

Accepted Answer

Most common (TRIUMPH-1 phase II): nausea 44%, diarrhoea 34%, vomiting 18%, constipation 15% — mostly during the first 4–8 weeks of titration, decreasing with adaptation. Serious (<1%): pancreatitis, cholecystitis, increased heart rate. Contraindications: personal or family history of medullary thyroid carcinoma, MEN 2, prior pancreatitis, pregnancy/breastfeeding. In the DOZA supervision programme we monitor TSH (0, 3, 6 months), ALT/AST, ECG if palpitations are reported. If not tolerated — step the dose down by one.
