Androgen-receptor agonism; phenylpropionate is a shorter ester than enanthate.
Composition / Profile
- Active compound: Testosterone Phenylpropionate
- Drug class: Injectable androgen / anabolic steroid (medium-short ester)
- Pack / dose (this listing): 10ml / 100mg
Format
- Oil-based (or aqueous, where noted) solution for intramuscular injection
- Pack / dose: 10ml / 100mg
Dosage & Usage Patterns
- Bodybuilding (commonly cited): Commonly cited: ~50–100 mg every 2–3 days when used in blends, or as part of a mixed-ester testosterone product; shorter ester requires more frequent injections than enanthate/cypionate.
- Clinical / general reference: Reported ranges are individual; shorter ester means more frequent injection.
- Half-life: ~1.5-2 days.
- Protocols vary by individual, compound stack, and bloodwork — figures above reflect community-reported patterns, not medical recommendations.
Effects
Reported benefits (commonly cited)
- Faster peak than long esters.
- Contributes to a staggered testosterone release in multi-ester blends.
- Androgenic/anabolic effects consistent with testosterone.
Reported side effects
- Acne.
- Water retention.
- Gynecomastia.
- Injection-site irritation.
- Testicular atrophy.
- Raised hematocrit.
Key Interactions
- Aromatizes to estradiol.
- Raises hematocrit.
Post-Cycle Considerations
- Faster clearance than long esters.
- Recovery timing adjusts accordingly.
Precautions
- More frequent injections.
- Sterile technique important.
Common Misconception
Myth: shorter esters ‘don’t suppress’ the axis.
Evidence: all exogenous testosterone suppresses the HPTA.
