The Finishing Compound for a Stage-Ready Look
Masteron (Drostanolone Propionate) is a DHT-derived anabolic steroid prized not for sheer size gains, but for its ability to harden, define, and sharpen a physique. Originally developed for medical use, Masteron has become a staple among competitive athletes preparing for contests, photo shoots, or any phase where presentation is everything.
Unlike heavy bulking compounds, Masteron delivers moderate anabolic activity with low androgenic side effects, making it the ideal choice for athletes who want a dry, chiseled look without water retention.
(Cycles & Uses):
When to Use Masteron
Masteron is best deployed during cutting and pre-contest phases. While it is not a primary muscle-building agent, its aesthetic enhancement properties make it invaluable in the final weeks of a cycle. Athletes often introduce Masteron 8–10 weeks out, or specifically in the last 2–4 weeks before stepping on stage or in front of a camera.
Its synergy with compounds like Testosterone Propionate, Trenbolone Acetate, and Anavar makes it an excellent addition to a finishing stack — helping athletes achieve a hard, vascular, granite-like appearance under the lights.
(Dosages & Administration):
Administration (Educational Use Only)
-
Typical performance range: 200–400mg per week
-
Most commonly introduced during the final 8–10 weeks of a cycle
-
Lower doses (~200mg/week) are favored for pre-contest prep to enhance definition and hardness
-
Higher doses (up to 400mg/week) are reserved for experienced users, though Masteron is not designed for mass gain
Masteron’s role is specialized, not foundational — its true power lies in refining and hardening a physique, not building it from scratch.

We have put together some commonly asked questions
Everything You Need to Know Before You Start
How does Immortal’s protocol system actually work?
Our protocol is precision engineered to restore optimal hormone balance. After your online assessment, our licensed physicians review your health profile and prescribe a tailored treatment. Your personalized meds are discreetly delivered, with ongoing support and adjustments based on your progress.
What’s included in the pricing — and what am I really paying for?
You’re paying for a complete medical-grade system: no doctor prescription needed, premium pharmaceutical compounds, lab-tested formulation, discreet delivery, and 24/7 patient support. No hidden fees — just results-driven wellness in every dose.
What’s the best way to set fitness or hormone goals before starting?
Start by identifying what you want to change energy, muscle mass, fat loss, focus, libido. Our onboarding flow guides you through a detailed goal setting process, and your assigned physician tailors treatment to get you there faster, safer, and smarter.
Is shipping discreet? Will anyone know what’s in the box?
Yes. Every package is shipped in discreet, unmarked boxes with no mention of what’s inside. Your treatment and privacy are our priority always protected, always confidential.
How fast can I expect results from testosterone therapy?
Most users report noticeable results within 2–4 weeks including sharper focus, improved drive, leaner muscle tone, and better recovery. Full benefits compound over 8–12 weeks with consistency.
What if I miss a dose, will it affect my cycle?
Missing one dose won’t drastically affect your progress. Just resume your regular schedule but consistency is key for optimal hormone balance. If you miss multiple doses, reach out to your care team and they’ll guide your next steps.
