Helios 5.8 mg is an oil-based injectable blend of Clenbuterol (30 mcg) and Yohimbine (5.6 mg) manufactured by Dragon Pharma and dosed at 5.8 mg/mL in a 10 mL vial.
Helios 5.8 mg is a specialized injectable formulation combining two compounds that act on the adrenergic system through different mechanisms. Clenbuterol is a beta-2 adrenergic agonist that provides bronchodilating properties and is indicated for the management of horses affected with airway obstruction. Yohimbine is an alpha-2 adrenergic antagonist that has veterinary applications for reversing xylazine sedation in dogs and deer. In non-medical bodybuilding contexts, this combination is commonly referenced for its potential effects on localized fat reduction.
Clenbuterol is approved by the FDA for oral use in horses only, under the brand name VENTIPULMIN, and federal law restricts it to use by or on the order of a licensed veterinarian. Yohimbine is similarly regulated for veterinary use, with approved applications including reversal of xylazine sedation in dogs and deer. Neither compound is approved for human use in this combination or for bodybuilding purposes. The injectable Helios formulation originated in bodybuilding circles as a method for targeted administration into areas of stubborn adipose tissue.
The rationale for combining these compounds relates to their complementary effects on fat cell metabolism. Clenbuterol directly stimulates fat cells and accelerates the breakdown of triglycerides into free fatty acids. Yohimbine blocks alpha-2 receptors, which allows for increased release of norepinephrine, further promoting lipolysis. This combination of beta-stimulating and alpha-blocking properties is cited in bodybuilding literature as an approach for localized fat reduction, though such use is not supported by regulatory approval or rigorous clinical evidence.
Helios 5.8 mg uses MCT oil as its carrier, providing an oil base for the Clenbuterol and Yohimbine formulation. The 5.8 mg/mL concentration delivers both active compounds in a single injectable preparation.
Helios combines two compounds with distinct mechanisms of action on the adrenergic system. Clenbuterol is a beta-2 adrenergic agonist with bronchodilating and thermogenic properties, while Yohimbine is an alpha-2 adrenergic antagonist traditionally used for its effects on sympathetic nervous system activity.
Clenbuterol (4-amino-alpha-[(tert-butylamino) methyl]-3, 5-dichlorobenzyl alcohol hydrochloride) is a beta-2 adrenergic agonist that provides bronchodilating properties with minimal effect on the cardiovascular system at therapeutic doses. In horses, it is indicated for the management of airway obstruction such as occurs in chronic obstructive pulmonary disease.
Yohimbine is classified as an alpha-2 adrenergic antagonist. It is used in veterinary medicine to reverse the effects of xylazine sedation in dogs and deer. Its mechanism of action involves blocking alpha-2 receptors, which are involved in the regulation of norepinephrine release.
The combination of these two compounds in an injectable formulation is not an approved medical or veterinary product. It is a preparation that originated in bodybuilding communities for potential localized fat reduction applications.
In non-medical bodybuilding contexts, Helios is commonly referenced as being administered via subcutaneous injection directly into areas of stubborn fat accumulation. A typical protocol references starting with 0.5 mL per day and gradually increasing to a maximum of around 2 mL per day, with injection sites including the abdominal area, love handles, and thighs. The product is typically used in cycles of up to 4 weeks due to concerns about beta-2 receptor downregulation.
Dragon Pharma offers several products relevant to fat loss and body composition goals. The standalone Clenbuterol provides a single-compound option for those seeking beta-2 agonist effects without the alpha-2 antagonist component. For broader cutting cycles, Dragon Pharma offers Cut Long 300 and Cut Mix 150.
The unique aspect of Helios is its combination of two adrenergic compounds in an injectable form, which is not replicated by any other single Dragon Pharma product. For users interested in other aspects of body composition, the T3 thyroid hormone product is also available.

Laboratory results apply to the specific tested sample represented in each published report and should not be interpreted as a measurement of every vial or production batch.
The information below is provided for educational reference only. Clenbuterol and Yohimbine are veterinary prescription medications; medical use in humans requires appropriate diagnosis, clinical supervision and ongoing monitoring. Non-medical use falls outside approved indications.
In veterinary practice, Clenbuterol (as VENTIPULMIN Syrup) is administered orally to horses at an initial dose of 0.8 mcg/kg twice daily, with stepwise increases up to 3.2 mcg/kg twice daily based on response. Yohimbine is administered intravenously to dogs at 0.11 mg/kg for reversal of xylazine sedation. In non-medical bodybuilding contexts, Helios is commonly referenced as being administered at 0.5 mL per day initially, gradually increasing to a maximum of approximately 2 mL per day, with use limited to cycles of up to 4 weeks.
| Use Case | Common Reference Range | Administration Frequency |
|---|---|---|
| Veterinary (Clenbuterol, horses) | 0.8–3.2 mcg/kg | Twice daily |
| Veterinary (Yohimbine, dogs) | 0.11 mg/kg | Single IV dose |
| Bodybuilding (non-medical) | 0.5–2 mL / day | 1–2 injections daily |
In non-medical bodybuilding contexts, Helios is typically used as a standalone product for localized fat reduction during cutting phases. It is sometimes referenced alongside other fat-loss agents such as T3 or Clenbuterol, though combining multiple adrenergic stimulants increases the risk of cardiovascular side effects.
The product is typically cycled for no more than 4 weeks due to concerns about beta-2 receptor downregulation, which can reduce effectiveness with prolonged use. A washout period is commonly referenced before repeating a cycle.
The combination of Clenbuterol and Yohimbine can produce significant stimulant effects. Common side effects referenced in bodybuilding contexts include increased heart rate, tremors, nervousness, restlessness, excessive sweating, and loss of appetite. Yohimbine is also known to cause anxiety and flu-like symptoms in some users.
Because both compounds affect the cardiovascular system, blood pressure and heart rate monitoring is important. Individuals with pre-existing cardiovascular conditions should avoid this product entirely.
Helios is not a hormonal compound and does not suppress endogenous testosterone production. Therefore, post-cycle therapy is not typically required after use. However, the product may be used as part of a broader cutting cycle that includes anabolic steroids, in which case PCT protocols would be determined by the other compounds used.
For those using Helios alongside suppressive compounds, agents such as Clomid or Nolvadex may be referenced for recovery.
Dosing strategies and support protocols should be adjusted based on experience level and individual tolerance. The information above is for educational reference and does not constitute medical advice.
Clenbuterol and Yohimbine are veterinary prescription medications that are not approved for human use in this combination. Both compounds can produce significant cardiovascular and neurological effects.
Clenbuterol is approved by the FDA only for oral use in horses under the brand name VENTIPULMIN, and federal law restricts it to use by or on the order of a licensed veterinarian. The label explicitly states "Not for use in humans" and warns that ingestion may cause undesirable reactions including elevated pulse rate, blood pressure changes, and ECG changes.
Yohimbine is approved for veterinary use in dogs and deer for specific indications, with federal law similarly restricting it to veterinary use. Non-medical use of either compound in humans falls outside approved indications and may carry significant health risks.
Helios is not an approved human medication. Use for bodybuilding or fat reduction purposes falls outside approved veterinary indications and may increase the risk of serious cardiovascular and neurological adverse effects.
Clenbuterol, like other beta-adrenergic agonists, can produce significant cardiovascular effects including elevated pulse rate, blood pressure changes, and ECG changes. In horses, adverse reactions during treatment include mild sweating, muscle tremor, restlessness, urticaria, and tachycardia, with ataxia observed in 1.3% of horses in clinical studies.
Yohimbine is known to cause anxiety, tremors, and increased heart rate. The combination of these two compounds may amplify stimulant effects on the cardiovascular and central nervous systems.
In non-medical bodybuilding contexts, side effects commonly referenced include loss of appetite, dizziness, nervousness, irregular heartbeat, nausea, excessive sweating, and diarrhea.
Both Clenbuterol and Yohimbine affect the cardiovascular system. Individuals with existing heart conditions, hypertension, or a history of cardiac arrhythmias should avoid these compounds. The VENTIPULMIN label states that it should not be used in horses suspected of having cardiovascular impairment due to the risk of tachycardia.
Yohimbine may interact with medications affecting the sympathetic nervous system. Anyone considering use of this product should consult a qualified healthcare professional regarding potential contraindications.
If this product is used in any context, monitoring of heart rate and blood pressure is important given the cardiovascular effects of both compounds. Body temperature and signs of excessive stimulation should also be monitored.
