Why is Methandienone used only in the first 4 weeks?

Methandienone serves as a kickstart because the long esters require 3–4 weeks to reach steady state. The oral phase is limited to 4 weeks due to 17α-alkylation and the associated hepatic load.

Can I use this stack as a beginner?

No. Running three compounds simultaneously makes it difficult to identify the cause of any side effects. Beginners should start with a testosterone-only cycle.

How much mass is realistic?

With appropriate caloric intake (+300–500 kcal) and progressive training, 6–10 kg of total mass over 12 weeks is typical, with approximately 3–5 kg of lean mass retained after water loss.

Do I need an aromatase inhibitor?

Keep Anastrozole on hand and use it only if symptoms arise (water retention, sensitive nipples) at a low dose – prophylactic full blockade will blunt mass gains.

Due to the Decanoate half-life of 6–7 days, begin no earlier than 4 weeks after the last injection; starting sooner will render PCT ineffective.

Mass Protocol is a pre-configured mass-building stack combining Testosterone Enanthate 250 mg/ml, Nandrolone Decanoate 250 mg/ml and Methandienone 10 mg – three complementary anabolics in one bundle designed for a 12-week bulk phase.

Mechanism of Action in Combination

Testosterone Enanthate binds the androgen receptor and drives muscular protein synthesis via the mTOR signalling pathway. Nandrolone Decanoate increases collagen synthesis and nitrogen balance while exhibiting low DHT conversion – it reduces to dihydronandrolone rather than DHT. Methandienone accelerates glycogen storage and cell volumisation, delivering a noticeable kickstart while the long esters reach effective plasma levels.

Stack Logic

The half-lives are matched to work together: Enanthate (t½ approx. 4–5 days) and Decanoate (t½ 6–7 days) maintain stable plasma levels with two injections per week. Methandienone (t½ 3–6 hours) bridges the loading phase orally. This triple combination targets mass gain through three independent pathways: receptor activation, nitrogen retention and cell volume.

Bundle Contents

3× EnanTrex 250 – Testosterone Enanthate 250 mg/ml, 10 ml vial (Dragon Pharma)
2× Nandrolone Decanoate 250 mg/ml, 10 ml vial (Hilma Biocare)
1× Methandienone 10 mg, 100 tablets (Hilma Biocare)

Who This Stack Is For

Advanced athletes who have completed at least two solo cycles and are targeting 6–10 kg of total mass (including 3–5 kg of lean muscle) during a 12-week bulk phase. Not suitable for beginners – see warnings.

Usage

Complete a full baseline blood panel before Week 1 (full blood count, lipids, liver enzymes, testosterone).
Inject Testosterone Enanthate and Nandrolone Decanoate intramuscularly every Monday and Thursday.
Take Methandienone in Weeks 1–4 split across 2–3 doses with meals.
Log bodyweight, strength and blood pressure weekly.
Begin PCT no earlier than 4 weeks after the last injection (allow for Decanoate half-life clearance).
Plan a post-PCT rest period at least as long as the cycle duration.

Warnings

Contraindications

Do not use in cases of prostate or breast carcinoma, pregnancy, breastfeeding, under 18 years of age, or severe hepatic or renal impairment. The combination of three suppressive or hepatotoxic compounds is reserved exclusively for experienced users.

Side Effects

Commonly expected: water retention, elevated blood pressure, reduced HDL cholesterol, acne and, in predisposed individuals, androgenic hair loss. Methandienone is hepatotoxic (17α-alkylated); Nandrolone may affect libido via prolactin elevation. Gynaecomastia risk exists due to aromatisation of Testosterone and Methandienone.

Monitoring

Full blood count including haematocrit before the start and at Week 6; liver enzymes (ALT, AST, GGT) weekly to bi-weekly throughout the Methandienone phase. Measure blood pressure twice weekly. If haematocrit exceeds 52%, consider dose reduction.

PCT

Begin 4 weeks after the last injection to account for the Decanoate half-life: Tamoxifen 20 mg/day plus Clomiphene 50 mg/day for 4 weeks, optionally HCG 1,500 IU twice weekly during the first 2 PCT weeks. See our PCT Complete Protocol as a ready-made bundle.

Enantat 250 250mg/ml 10ml Vial by Dragon-Pharma

Dragon-Pharma Enantat 250 delivers Testosterone Enanthate at 250 mg/ml in a multi-dose 10 ml vial — a long-chain ester formulation purpose-built for infrequent injection schedules that still maintain stable serum testosterone across a full week. Among all commercially available testosterone esters, the enanthate chain occupies a deliberate middle ground: slower to peak than propionate, faster to clear than undecanoate, making it the default reference ester against which all others are benchmarked. Quality assurance at Dragon-Pharma is structured around GMP-certified fill-finish operations; each production lot passes HPLC content-uniformity testing and LAL endotoxin validation before release.

Nandrolone Decanoate 250mg/ml 10ml Vial by Hilma Biocare

Hilma Biocare Nandrolone Decanoate 250 mg/ml is a long-acting injectable anabolic agent formulated at a clinically relevant concentration, recognised in sports pharmacology for the progressive androgen receptor desensitization it induces — making structured cycle duration and planned off-time a pharmacological necessity, not a preference. Each 10 ml multi-dose vial delivers consistent dosing flexibility across a full protocol, supporting both lean mass and recovery phases. Quality assurance is embedded at every stage: sterility by LAL endotoxin assay, potency verification by HPLC, and finished-product release under EU-aligned GMP standards.

Methandienone 10mg/tab 100 Tablets by Hilma Biocare

Hilma Biocare Methandienone 10mg per tablet is an oral 17α-alkylated anabolic steroid formulated specifically to accelerate nitrogen retention during the frontloading phase of a long-ester cycle, bridging the pharmacokinetic gap before injectable compounds reach steady-state plasma concentrations. Each 100-tablet pack provides a precisely titratable loading architecture — 10 mg steps allow a practitioner to ramp an initial kickstart dose and taper systematically without fractional tablet uncertainty. Analytical release: every batch cleared through HPLC-verified API content uniformity and LAL endotoxin screening before distribution.
