Sold as 10-vial kits · minimum order
We don't sell single vials. Every order is a sealed 10-vial research kit — it's how serious labs and long-protocol researchers actually buy, and it's how we keep quality and price honest.
- ✓ Lower €/mg — batching 10 vials cuts our fill cost, and we pass it to you (per-vial price is 40–60% lower than typical single-vial pricing).
- ✓ One batch, one COA — all 10 vials come from the same HPLC-verified lot, so your data stays consistent across a full study.
- ✓ Real supply for real protocols — a 10-vial kit covers ~30–90 days of research depending on dose, so you're not re-ordering mid-study.
- ✓ One shipment, one customs pass — fewer parcels = lower risk, lower shipping cost per vial, faster to your bench.

What is Tirzepatide?
Tirzepatide is a 39-amino-acid synthetic peptide engineered as a balanced dual agonist of the GIP and GLP-1 receptors. Its C20 fatty diacid moiety enables albumin binding and supports an extended half-life suitable for chronic-exposure research.
Mechanism of action
Co-activation of GIP and GLP-1 receptors for incretin pathway studies.
Primary research areas
Energy expenditure, lipid metabolism, insulin sensitivity.
Research notes
- Comparative studies frequently benchmark tirzepatide against semaglutide for incretin pathway crosstalk.
- Used in lipidomic and mitochondrial biogenesis research panels.
Tirzepatide: expanded research context
Tirzepatide is a dual GLP-1/GIP receptor agonist approved for type-2 diabetes (Mounjaro) and chronic weight management (Zepbound). Its GIP arm is thought to potentiate GLP-1 driven satiety and improve tolerability at higher exposures, which is reflected in the class-leading HbA1c and weight endpoints seen across the SURPASS and SURMOUNT programmes.
Half-life is approximately five days, supporting weekly dosing. Beyond metabolic endpoints, tirzepatide has been evaluated for heart-failure with preserved ejection fraction (SUMMIT), obstructive sleep apnoea (SURMOUNT-OSA) and MASH — a broader cardiometabolic remodelling profile than earlier GLP-1 mono-agonists.

SURPASS-2: tirzepatide vs semaglutide 1 mg in T2D
New England Journal of Medicine · 2021
Tirzepatide 5/10/15 mg produced greater HbA1c and weight reductions than semaglutide 1 mg at 40 weeks in adults with T2D.
SURMOUNT-1: tirzepatide in obesity
New England Journal of Medicine · 2022
72-week trial in adults with obesity without diabetes — mean weight reductions up to ~22.5% at the highest dose, sustained across follow-up.
SURMOUNT-OSA: tirzepatide in obstructive sleep apnoea
New England Journal of Medicine · 2024
Tirzepatide reduced apnoea-hypopnoea index and improved cardiometabolic markers in adults with obesity and moderate-to-severe OSA.
SUMMIT: tirzepatide in HFpEF with obesity
New England Journal of Medicine · 2024
Tirzepatide reduced a composite of cardiovascular death and worsening HF events and improved KCCQ symptom scores in HFpEF with obesity.

Customer reviews
What researchers say about Tirzepatide
- Verified
COA matched batch number exactly
Ordered three batches of BPC-157 over four months. Each shipment arrived cold-packed with a COA and the batch numbers cross-checked against the public testing database. Purity reported between 98.7% and 99.2% — consistent with what we measured in-house by HPLC.
Dr. M. AnderssonStockholm, Sweden - Verified
Fast UK delivery, clean reconstitution
Discreet packaging, arrived in 48 hours to London. Lyophilised cake was firm, dissolved completely in bac water with no cloudiness. Dose math in IU on the calculator made repeat dosing trivial.
J. WhitmoreLondon, UK - Verified
Best documentation I've seen from a supplier
We compared three suppliers as part of a sourcing audit. Regena was the only one with chromatograms, retention times and lab-named COAs published per batch. That's the standard the rest of the industry should meet.
Prof. L. RomanoMilan, Italy - Verified
Good product, customs took an extra day
Product itself is excellent — clean reconstitution, COA available. Customs added 24 hours which is outside Regena's control. Support replied within an hour when I asked for an update.
K. PetersenCopenhagen, Denmark - Verified
Independent lab agreed with stated purity
We sent a sub-sample to an independent lab. Their result was within 0.4% of the published Regena COA. That's a level of transparency you almost never see in research-peptide sourcing.
Dr. S. PatelBirmingham, UK - Verified
Cold chain held the whole way
Temperature indicator strip in the package stayed in the green. Vials still chilled on arrival despite a 3-day route. Whoever packs these boxes knows what they're doing.
