Anavar (oxandrolone) and testosterone cypionate are popular compounds in
bodybuilding due to their ability to increase lean muscle mass, improve strength, and aid recovery while keeping water retention minimal. When combined with Master‑on (drostanolone propionate), which is known for its powerful cutting properties, the resulting stack can provide both anabolic and androgenic benefits while helping athletes achieve a hard, defined look without excessive bulk.
The first step in constructing a successful Master‑On cycle is to determine your overall goal: bulking, cutting, or maintenance. For most users looking for a clean physique with enhanced muscle definition, a 12‑week stack that begins with a moderate dose of testosterone cypionate and incorporates Anavar early on, followed by Master‑On toward the end of the cycle, works best. The cycle is typically divided into three phases: an anabolic phase (weeks 1–6), a cutting phase (weeks 7–9), and a post‑cycle recovery phase (weeks 10–12).
Anavar dosage for a beginner is usually 20–30 mg per day. For more experienced users, the dose can rise to 40–50 mg daily, but this should be spread over two or three injections each week to avoid liver strain. Testosterone cypionate is injected once every seven days; standard beginner dosages range from 200 to 400 mg per week, whereas seasoned athletes may push up to 600–800 mg weekly for maximum anabolic effect. In a 12‑week Master‑On stack, the recommended testosterone cypionate dosage starts at 300 mg per week during the first six weeks, then increases to 500 mg per week from weeks seven through nine. The final three weeks are dedicated to post‑cycle therapy (PCT) with selective estrogen receptor modulators such as tamoxifen or clomiphene, and a low dose of testosterone is maintained to support hormone balance.
Master‑On itself is injected twice weekly for the entire 12‑week cycle at a dosage between 200 and 300 mg per week. The first phase (weeks 1–6) uses a lower dose of 150 mg per week to allow the body to acclimate, while weeks seven through nine see an increase to 250 mg per week. This progressive approach helps minimize androgenic side effects such as acne or hair loss. At the end of the cycle, the dosage is tapered off gradually over two weeks to avoid sudden hormonal withdrawal.
Master‑On cycles vary in length and composition depending on user preference. A common 8‑week cycle involves 150 mg per week for the first four weeks followed by 200 mg per week for the next four weeks. Some users prefer a longer, 16‑week stack that incorporates additional compounds such as trenbolone or stanozolol for maximum muscle gain before shifting to a cutting regimen with Master‑On and Anavar. However, extended use of Master‑On can increase the risk of liver toxicity and androgenic side effects, so it is generally recommended to keep the total exposure under 12–16 weeks.
When constructing a masteron cycle with test cypionate and anavar, start by mapping out each week’s injections:
Weeks 1–6: Testosterone cypionate 300 mg per week, Anavar 20–30 mg daily, Master‑On 150 mg per week.
Weeks 7–9: Testosterone cypionate increases to 500 mg per week, Anavar remains at 20–30 mg daily, Master‑On increases to 200 mg per week.
Weeks 10–12: No new injections; begin PCT and reduce testosterone cypionate gradually. If desired, a low dose of anavar (5–10 mg) can be used in the final two weeks to maintain anabolic support during recovery.
It is crucial to track your body’s response closely. Monitor liver function tests every four weeks when using anavar, as it is hepatotoxic at higher doses. Watch for estrogenic symptoms such as gynecomastia or water retention; if these arise, a mild aromatase inhibitor can be introduced, though test cypionate itself has low aromatase activity.
After the cycle, a robust PCT protocol is essential. A common regimen uses tamoxifen 40 mg per day for four weeks combined with clomiphene 50 mg daily for two weeks, followed by a tapering period of testosterone replacement at 200–300 mg weekly to maintain natural production until endogenous levels recover.
Master‑On cycles are especially effective when paired with an aggressive diet and training program. For bulking phases, high protein intake (1.5–2 g per kilogram of body weight) coupled with caloric surplus supports muscle growth. During cutting stages, a slight deficit (300–500 kcal below maintenance) combined with increased cardio helps preserve lean mass while promoting fat loss.
In summary, the ideal anavar and test cypionate Master‑On cycle balances anabolic support from testosterone, lean muscle preservation from anavar, and cutting power from masteron. By carefully titrating dosages across a 12‑week schedule, monitoring side effects, and employing a structured PCT, users can achieve significant gains in muscle definition with minimal risk of adverse outcomes.
