How to Reconstitute and Store

Reconstitution Protocol

1. Remove vial from refrigeration and allow to reach room temperature (10-15 minutes)
2. Add bacteriostatic water or sterile water slowly down the inside wall of the vial
3. Use gentle swirling motion; avoid shaking or vigorous agitation
4. Typical concentration: 0.5-2 mg/mL depending on protocol requirements
5. Filter through 0.22μm sterile filter if aseptic conditions require it

Storage Guidelines

Unopened powder: Store at 2-8°C (refrigerated), stable for 24+ months
Reconstituted solution: Store at 2-8°C, use within 28 days
Long-term storage: Create aliquots and store at -20°C to minimize freeze-thaw cycles
Light protection: Use amber vials or foil wrapping to protect from degradation

Frequently Asked Questions

Where is the best place to buy semaglutide in the UK for research?

We supply research-grade semaglutide with verified >99% purity, third-party COA, and complete HPLC/mass spectrometry documentation to UK laboratories and research institutions. Every order includes batch-specific analytical data, cold-chain shipping, and dispatch within 24-48 hours. Our peptides are trusted by academic and biotech research teams who require reliable, traceable compounds for metabolic and endocrine studies.

How do I mix semaglutide after it arrives?

Let the vial reach room temperature first (about 10-15 minutes). Add bacteriostatic water or sterile water slowly down the side of the vial—don’t spray it directly onto the powder. Use 1-2ml of water depending on your desired concentration. Gently swirl (don’t shake) until the powder fully dissolves. This usually takes 1-2 minutes. Once mixed, store it in the fridge at 2-8°C and use within 28 days for best stability.

What’s the difference between semaglutide and Ozempic?

Semaglutide is the active pharmaceutical ingredient, while Ozempic is a prescription brand name medication containing semaglutide formulated for clinical diabetes management. Research-grade semaglutide is supplied exclusively for laboratory investigation and is not manufactured to the pharmaceutical standards required for human administration. Ozempic undergoes extensive clinical testing and regulatory approval for medical use under physician supervision, whereas research peptides are intended only for scientific study in controlled environments.

Can you freeze semaglutide after mixing it?

Yes, you can freeze reconstituted semaglutide for extended storage. After mixing, immediately divide it into single-use aliquots and freeze at -20°C or ideally -80°C. Frozen aliquots remain stable for several months. However, avoid repeated freeze-thaw cycles as this degrades the peptide. Thaw only what you need for each experiment. Many researchers prefer to reconstitute fresh peptide for critical studies to ensure maximum potency and consistency.

How long does semaglutide last in the fridge after reconstitution?

Once reconstituted and stored at 2-8°C (standard refrigerator temperature), semaglutide maintains stability for up to 28 days. The extended half-life of this GLP-1 analogue contributes to better solution stability compared to shorter-acting peptides. Always protect from light using amber vials or foil wrapping. For experiments beyond 28 days, create frozen aliquots immediately after reconstitution rather than keeping one vial in the fridge long-term.

Semaglutide 5mg price UK – what should I expect to pay?

Pricing for research-grade semaglutide varies based on purity level, supplier verification, and included documentation. High-quality 5mg peptides with >99% purity and full COA typically range from £59.00 from legitimate UK suppliers.

Is semaglutide legal to buy in the UK without prescription for research?

Research-grade semaglutide can be purchased for legitimate laboratory use and scientific investigation by qualified researchers or institutions without a prescription, as it’s classified as a research chemical. However, it must not be used for human consumption, self-administration, or any clinical purpose. Prescription medications containing semaglutide (Ozempic, Wegovy) do require medical authorization. Research peptides are supplied strictly for scientific study in appropriate laboratory facilities under institutional guidelines.

Semaglutide vs tirzepatide – which is better for metabolic research?

Semaglutide is a selective GLP-1 receptor agonist, while tirzepatide is a dual GLP-1/GIP receptor agonist, making them suitable for different research questions. Choose semaglutide when investigating pure GLP-1 pathway mechanisms, incretin hormone signalling, or glucose-dependent insulin secretion. Tirzepatide is ideal for studies examining synergistic effects of dual incretin activation or comparative receptor pharmacology. Many research teams use both peptides in parallel protocols to understand individual versus combined incretin effects on metabolic outcomes.

What’s the difference between semaglutide and Wegovy for research purposes?

Both contain the same active molecule (semaglutide), but Wegovy is a prescription medication specifically approved for weight management at higher therapeutic doses (up to 2.4mg weekly), while research-grade semaglutide is supplied for laboratory investigation only. Wegovy undergoes pharmaceutical manufacturing with strict clinical dosing protocols and safety monitoring for medical use. Research peptides allow scientists to study the compound’s mechanisms in controlled experimental settings at researcher-determined concentrations without the regulatory constraints of approved medications.

Where can I buy legitimate semaglutide with certificate of analysis in UK?

Legitimate suppliers provide batch-specific certificates of analysis (COA) from independent third-party laboratories, not just in-house testing. Look for HPLC chromatograms showing >99% purity, mass spectrometry results confirming molecular weight (4,113.64 g/mol), and endotoxin testing for cell culture applications. We include complete analytical documentation with every order, maintain cold-chain shipping standards, and provide technical support for research applications. All peptides are manufactured under GMP conditions for research use.

All shipments include cold-chain packaging with insulated boxes and gel ice packs to maintain peptide integrity during transit. We dispatch Monday through Friday, with orders placed before 2pm typically processed same-day for next-working-day arrival.

Can I use semaglutide in cell culture experiments?

Yes, this peptide is widely used in cell culture research examining metabolic pathways, GLP-1 receptor activation, and insulin secretion mechanisms. Typical working concentrations range from 10 nM to 1 μM depending on cell type and experimental objectives. Pancreatic beta-cell studies often use 10-100 nM, while adipocyte or hepatocyte cultures may require higher concentrations. Always reconstitute in sterile conditions and filter through 0.22μm filters before adding to cell cultures to maintain aseptic conditions.

What purity level should I look for when buying semaglutide peptide?

Research-grade peptides should demonstrate ≥98% purity minimum, though >99% is strongly preferred for metabolic and endocrine studies where precision is critical. Lower purity products may contain synthesis byproducts or degradation fragments that interfere with GLP-1 receptor binding assays, insulin secretion measurements, or other sensitive experimental endpoints. Always verify purity through HPLC chromatography and mass spectrometry analysis. Request batch-specific COA showing both purity percentage and analytical methods used before incorporating into research protocols.
