Product Overview
Sildabol 100 mg by British Dragon
Sildabol 100 mg is an oral sildenafil citrate tablet manufactured by British Dragon and dosed at 100 mg per tablet, supplied in packs of 20 or 100 tablets.
Sildenafil Citrate Oral
Sildabol 100 mg contains sildenafil citrate, a selective phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil was initially developed as a treatment for hypertension and angina pectoris, a type of chest pain caused by reduced blood flow to the heart . It works by inhibiting the PDE5 enzyme, which is responsible for the breakdown of cyclic GMP (cGMP). By blocking this breakdown, sildenafil increases cGMP levels, leading to smooth muscle relaxation and increased blood flow .
In clinical medicine, sildenafil is FDA-approved for the treatment of erectile dysfunction and pulmonary arterial hypertension. The recommended dosage for erectile dysfunction is typically 50 mg taken approximately 1 hour before sexual activity, with a maximum single dose of 100 mg and a maximum frequency of once daily . A lower starting dose of 25 mg is recommended for patients over 65 years, those with hepatic or severe renal impairment, and those taking strong CYP3A4 inhibitors .
In non-medical bodybuilding and fitness contexts, sildenafil is sometimes referenced as a pre-workout supplement, with users theorizing that increased blood flow and nitric oxide signaling could enhance muscle pumps, endurance, and recovery . However, clinical evidence for performance benefits in healthy individuals at sea level remains limited, and a 2025 review concluded there is no good evidence that these medications significantly improve athletic abilities in standard environments . Such use falls outside approved indications.
Key Properties of Sildabol 100 mg

- Works by inhibiting cGMP breakdown to increase blood flow
- 100 mg per tablet represents the maximum recommended single clinical dose
- Rapid absorption with peak concentrations reached within 30–120 minutes
- 20 or 100 tablet pack sizes support research protocols
Product Profile
Sildenafil Citrate Profile
Sildenafil citrate is a selective PDE5 inhibitor that enhances erectile function by increasing cGMP levels and blood flow to the corpus cavernosum .
PDE5 Inhibitor
Sildenafil is a specific inhibitor of phosphodiesterase type 5 (PDE5), an enzyme responsible for the breakdown of cyclic GMP (cGMP) to 5-GMP. Upon sexual stimulation, nitric oxide (NO) is released from nerve terminals and endothelial cells, stimulating the synthesis of cGMP in smooth muscle cells. Cyclic GMP causes smooth muscle relaxation and increased blood flow into the corpus cavernosum. By inhibiting PDE5, sildenafil enhances this process by increasing the amount of cGMP available, facilitating the generation and maintenance of erections .
Sildenafil is rapidly absorbed after oral administration, with a mean absolute bioavailability of 41% (range 25–63%). Maximum observed plasma concentrations are reached within 30 to 120 minutes (median 60 minutes) of oral dosing in the fasted state. When taken with a high-fat meal, the rate of absorption is reduced, with a mean delay in Tmax of 60 minutes and a mean reduction in Cmax of 29%. Sildenafil and its major metabolite both have terminal half-lives of approximately 4 hours .
In non-medical bodybuilding contexts, sildenafil's vasodilatory properties have led to its discussion as a potential pre-workout agent. A 2013 study in healthy men found that daily administration of 25 mg sildenafil over 7 days led to a significant increase in mixed muscle protein fractional synthetic rate and reduced fatigue . However, a 2025 review concluded that for healthy individuals, there is no good evidence that PDE5 inhibitors significantly improve athletic abilities in a standard, sea-level environment .
Clinical Status
FDA-Approved for ED and PAH — Not for Performance Use
Sildenafil is FDA-approved for erectile dysfunction and pulmonary arterial hypertension. The 100 mg strength represents the maximum recommended single clinical dose for ED . Non-medical use for performance enhancement falls outside approved indications.
Sildabol 100 mg vs Other British Dragon Preparations
British Dragon offers several ancillary compounds used in non-medical bodybuilding contexts. Taldabol contains tadalafil, another PDE5 inhibitor with a longer half-life of approximately 17.5 hours . While sildenafil is typically used on-demand for a sharp, time-locked window of effect, tadalafil is often referenced for daily use due to its longer duration .
Sildenafil's distinguishing characteristic among PDE5 inhibitors is its shorter half-life and rapid onset, making it suitable for on-demand use rather than chronic daily coverage .
Dosage & Usage
Sildabol 100 mg Dosage & Usage
The information below is provided for educational reference only. Sildenafil is a prescription medication; medical use requires appropriate diagnosis, clinical supervision, and ongoing monitoring. Non-medical use falls outside approved indications.
Typical Dosage Ranges
In clinical practice for erectile dysfunction, the recommended dose is 50 mg taken approximately 1 hour before sexual activity, with a maximum single dose of 100 mg and a maximum frequency of once daily . A lower starting dose of 25 mg is recommended for patients over 65 years, those with hepatic or severe renal impairment, and those taking strong CYP3A4 inhibitors . In non-medical bodybuilding contexts, sildenafil is sometimes referenced at 25 to 50 mg pre-workout, though such use falls outside approved indications.
| Use Case | Common Reference Range | Frequency |
|---|---|---|
| Clinical (ED, standard) | 50 mg | Once daily as needed, 1 hour before |
| Clinical (ED, maximum) | 100 mg | Once daily maximum |
| Clinical (special populations) | 25 mg | Once daily as needed |
| Non-medical (pre-workout, reported) | 25–50 mg | 30–60 minutes before exercise |
These non-medical ranges represent community-reported practices and are not derived from controlled clinical trials for performance enhancement. A 2013 study used 25 mg daily in healthy men and found increased muscle protein synthesis and reduced fatigue, but the study was small and the clinical significance for performance remains unclear .
Stacking & Cycle Considerations
In non-medical bodybuilding contexts, sildenafil is sometimes referenced alongside other compounds for its vasodilatory effects. The rationale discussed is that increased blood flow could enhance nutrient delivery and muscle pumps during training . However, sildenafil is contraindicated with nitrates and riociguat due to the risk of severe hypotension, and caution is advised when used with alpha-blockers or antihypertensive medications .
No loading phase or tapering is required with sildenafil. The compound does not affect the HPTA, is not hepatotoxic at therapeutic doses, and does not require post-cycle therapy.
Managing Side Effects
The most common adverse effects reported with sildenafil include headache, flushing, dyspepsia, nasal congestion, and visual disturbances such as blue-tinted vision . Visual effects are related to mild inhibition of PDE6 in the retina .
Serious but rare adverse effects include non-arteritic anterior ischemic optic neuropathy (NAION), sudden hearing loss, and priapism (prolonged erection lasting more than 4 hours) . If an erection persists longer than 4 hours, immediate medical attention should be sought to prevent penile tissue damage .
Important
Individual Response Varies
Sildenafil has approved dosing for specific medical indications. Any information about non-medical use is derived from user-reported practices and is not validated by controlled clinical research. This information does not constitute medical advice.
Safety & Information
Sildenafil Citrate Safety Information
Sildenafil is a prescription medication with known risks that require clinical oversight. It is contraindicated with nitrates and riociguat due to the risk of severe hypotension .
Important Safety Information
Sildenafil is contraindicated in patients using organic nitrates in any form, either regularly or intermittently, because of the greater risk of hypotension. It is also contraindicated with riociguat, a guanylate cyclase stimulator, as PDE5 inhibitors may potentiate its hypotensive effects .
Sildenafil has systemic vasodilatory properties that resulted in transient decreases in supine blood pressure in healthy volunteers (mean maximum decrease of 8.4/5.5 mmHg). Use with caution in patients with left ventricular outflow obstruction, severely impaired autonomic control of blood pressure, and those who have suffered a myocardial infarction, stroke, or life-threatening arrhythmia within the last 6 months .
Important
Non-Medical Use
Non-medical use of sildenafil falls outside approved indications. Product purity does not establish that non-medical use is safe or appropriate for an individual. Sildenafil is not recommended for those for whom sexual activity is inadvisable due to cardiovascular status .
Potential Adverse Effects
The most common adverse reactions reported in clinical trials include headache, flushing, dyspepsia, nasal congestion, and visual disturbances including blue-tinted vision . These visual effects are related to mild inhibition of PDE6 in the retina .
Serious but rare adverse effects include non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision; sudden decrease or loss of hearing, sometimes accompanied by tinnitus and dizziness; and priapism (painful erections greater than 6 hours in duration). In the event of an erection that persists longer than 4 hours, the patient should seek immediate medical assistance .
Conditions Requiring Medical Evaluation
Sildenafil is not appropriate for everyone. Contraindications include concomitant use of nitrates or riociguat, and known hypersensitivity to sildenafil . Caution is advised in patients with cardiovascular disease, left ventricular outflow obstruction, and those on antihypertensive therapy .
The evaluation of erectile dysfunction should include a determination of potential underlying causes and the identification of appropriate treatment following a complete medical assessment .
Monitoring During Therapy
Because sildenafil has no approved human use for performance enhancement, no standardized monitoring protocols exist for non-medical use. In clinical settings, monitoring of blood pressure may be considered when co-administering blood pressure-lowering drugs with sildenafil .
