Tesamorelin 20 mg
Tesamorelin 20 mg is a synthetic peptide widely used in advanced laboratory research focused on endocrine signaling and metabolic processes. As an analogue of growth hormone-releasing hormone (GHRH), it supports studies involving hormone regulation, peptide-receptor interactions, and biochemical pathway analysis. Because of its defined structure and stability, Tesamorelin remains a valuable compound for controlled in-vitro experiments and analytical workflows.
CAS Number: 218949-48-5
Molecular Formula: C₂₂₁H₃₆₆N₇₂O₆₇S
Molecular Weight: ~5135.9 g/mol
Content: 20 mg (lyophilised)
Solubility: Tesamorelin 20 mg in 3 mL is a high‑concentration solution and may form a gel‑like mass during reconstitution. To minimise this risk, depressurise the vial first and add diluent very slowly against the vial wall. If a gel forms, it can often be dispersed by placing the vial in warm water at ~30 °C (never exceed 40 °C) and allowing gentle agitation for 1–2 hours until fully dissolved.
Key Features
Purity: ≥98% (HPLC-verified)
Form: Sterile, freeze-dried (lyophilised) powder
Documentation: Certificate of Analysis (COA) provided for each batch
Origin: UK-stocked for fast, tracked Royal Mail delivery
Storage: –20°C in a temperature-controlled facility until dispatch

Storage & Handling
Proper storage & handling are essential to maintain product integrity and
support consistent research outcomes.
1. Storage condition
Products should be stored according to be handling guidance provided with each batch.
- Store in a cool, stable environment
- Avoid prolonged exposure to heat or direct light
- Minimize unnecessary handling
- Keeping sealed when not in use
Proper storage practices help preserve product integrity and consistency.
2. Handling Guidance
Apexion produce and presented in a pre-measured format designed to reduce unnecessary handling variability.
- Avoid repeated environmental exposure
- Handle carefully during use and storage
- Follow batch-specific guidance where provided
- Inspect packing integrity before use
Careful handling supports product consistency and minimizes risk of contamination.
3. Format & Stability
Questions regarding stability in pens versus vials are common.
Stability is influenced by multiple factors including formulation, storage conditions, temperature fluctuation, and handling practices – not container format alone.
Follow all storage instructions for best results.
4. Packaging & Verification
Each product includes:
- Batch identification
- QR verification support
- Traceable packaging
- Documentation status visibility
Products should only be used if packaging integrity is intact.
Batch specific handling guidance may very depending on product formulation and documentation status.
Always refer to the information provided woth your specific batch.
Format & Stability
Questions about peptide stability in pens vs vials are common.
Stability depends on formulation, handling, and storage – not the container alone.
Our Commitment
Apexion products are formulated, filled, and packaged under controlled conditions to support stability & consistency. Proper storage and handling are essential to preserve integrity.
Understanding Stability
Stability is influenced by multiple factors, including:
- Peptide formukation and Purity
- Storage temperature and environmental condition
- Light exposure
- Handling frequency and duration
- Seal integrity and air exposure
Because of these factors, following recommended storage and handling practices is key to maintaining product integrity regardless of format.
