Enquire This Compound

Clenbuterol Hydrochloride is the hydrochloride salt of clenbuterol, identified by CAS Number 21898-19-1. It has the molecular formula C12H19Cl3N2O and a molecular weight of approximately 313.65 g/mol. The compound belongs to the beta-adrenergic agonist category and has bronchodilator activity through its interaction with beta-2 adrenergic receptors.

Nova Techsciences associates Clenbuterol Hydrochloride with its SPIROCLEN oral tablet range. The current compound page lists the active ingredient, CAS number and tablet presentation. Website information should remain consistent with the finished packaging, batch records, structured data and Certificate of Analysis.

Compound Overview

  • Compound name: Clenbuterol Hydrochloride
  • CAS Number: 21898-19-1
  • Molecular formula: C12H19Cl3N2O
  • Molecular weight: Approximately 313.65 g/mol
  • Compound class: Beta-adrenergic agonist
  • Associated range: SPIROCLEN
  • Brand: Nova Techsciences

Clenbuterol Hydrochloride should be distinguished from clenbuterol base, which has a different CAS identifier. Using the correct salt name and chemical number helps prevent inconsistencies across labels, laboratory reports and technical documentation.

Scientific and Regulatory Context

Clenbuterol stimulates beta-2 adrenergic receptors in smooth muscle. This explains its historical investigation and authorised use as a bronchodilator in certain countries. However, its regulatory status is not uniform across Europe. EMA records show that clenbuterol-containing human medicines have held national authorisations in only certain EU member states, so therapeutic claims must be checked against the current authorisation in each intended market.

For the United Kingdom, Netherlands and other European markets, Nova Techsciences should clearly disclose the compound’s marketing-authorisation status, legal supply category, responsible organisation and adverse-event reporting process.

Quality Control and Traceability

A reliable Clenbuterol Hydrochloride compound profile should be supported by documented analytical controls. Appropriate records may include raw-material identification, active-compound assay, impurity analysis, reference-standard comparison, tablet content uniformity, dissolution testing, stability assessment and packaging-integrity verification.

Every manufactured batch should carry a unique number linked to its production history and laboratory-release results. Claims concerning pharmaceutical quality, purity or manufacturing standards should only be published when supported by current, verifiable documentation.

Important Safety Information

Clenbuterol can affect the cardiovascular and nervous systems. Reported concerns include palpitations, increased heart rate, tremor and nervousness. People with cardiovascular disease, abnormal heart rhythm, hypertension or hyperthyroidism may face additional risks.

Clenbuterol Hydrochloride should not be presented for weight loss, physique enhancement, athletic performance or unsupervised use. It is classified as a prohibited anabolic agent under the 2026 World Anti-Doping Agency Prohibited List and is prohibited both in and out of competition.

Stanozolol USP

Stanozolol USP is an anabolic-androgenic steroid identified by CAS Number 10418-03-8. Nova Techsciences associates it with the lower-strength STANOVA tablet presentation. Its documentation should independently address liver, cardiovascular, hormonal and reproductive risks.

Stanozolol STANOVA-50

STANOVA-50 contains the same Stanozolol active compound but in a different product strength. It retains CAS Number 10418-03-8, while its packaging, strength, batch details and safety warnings should be clearly distinguished from the lower-strength presentation.

Clomiphene Citrate

Clomiphene Citrate is a selective oestrogen receptor modulator identified by CAS Number 50-41-9. It is associated with medically supervised treatment of ovulatory dysfunction and requires separate contraindication, pregnancy, visual-effect and ovarian-response information.

Testosterone Propionate

Testosterone Propionate is an esterified testosterone compound identified by CAS Number 57-85-2. It is chemically and pharmacologically different from Clenbuterol Hydrochloride and requires independent information covering authorised status, contraindications, sterility controls and hormonal monitoring.

Testosterone Blend

A Testosterone Blend combines more than one testosterone component. The individual esters and strengths should be identified separately rather than relying only on CAS Number 58-22-0, which identifies the parent testosterone compound.

Clenbuterol Hydrochloride should ultimately be presented through accurate chemical identification, transparent batch documentation, balanced safety information and clearly verified regulatory status.
