Why does this stack run for 14 weeks?

The Undecylenate ester has a half-life of approximately 14 days and requires 5–6 weeks to reach steady state. Shorter Boldenone cycles end before the compound is fully effective.

Does Boldenone really increase appetite?

Yes, this is a well-documented effect. In a recomposition context it helps to maintain high protein intake – it may be disruptive during a strict cut.

Is this stack suitable for beginners?

As a very first stack: conditionally – after a completed Testosterone-only cycle it is the mildest multi-compound option in the range, owing to the absence of 19-nor compounds.

Why does Oxandrolone start only in week 7?

By that point the injectable compounds are fully active; Oxandrolone complements the second half as an oral component, limiting hepatic stress to 8 weeks.

How much muscle gain is realistic?

3–5 kg of quality lean muscle over 14 weeks at a moderate caloric surplus – noticeably leaner than with the Mass Protocol.

Key takeaways

Build lean muscle without heavy aromatisation
Receive 3× Test E, 3× Boldenone and 2× Oxandrolone in the bundle
Use Boldenone for appetite support and a vascular look
Introduce Oxandrolone strategically in the second half of the cycle
Avoid 19-nor compounds and their associated prolactin risk
Plan for 14 weeks due to the long Undecylenate half-life

Lean Gains Protocol is a pre-configured recomposition stack of Testosterone Enanthate 250 mg/ml, Boldenone Undecylenate 250 mg/ml and Oxandrolone 10 mg – designed for 14 weeks of clean, high-quality muscle growth.

The Logic of Lean Gains

Boldenone Undecylenate aromatises to oestradiol at roughly 50 % of the rate of Testosterone – the result is muscle growth without a bloated appearance. Oxandrolone acts anabolically without aromatisation, complementing the second half of the cycle as a mild oral component. The Testosterone Enanthate base keeps libido, mood and anabolic support consistently stable.

Why 14 Weeks

The Undecylenate ester has a half-life of approximately 14 days and only reaches steady state after 5–6 weeks. Short Boldenone cycles waste exactly this build-up window – which is why this stack is deliberately long. Oxandrolone starts only in week 7, once the injectable compounds are fully active.

What's Included

3× Enantat 250 – Testosterone Enanthate 250 mg/ml, 10 ml vial (Dragon Pharma)
3× Boldenone Undecylenate 250 mg/ml, 10 ml vial (Hilma Biocare)
2× Oxandrolone 10 mg, 100 tablets (Hilma Biocare)

Who Is This Stack For

Athletes who prioritise quality over quantity: visible muscle growth with controlled body fat, without the complexity of 19-nor compounds. Also suitable as a first multi-compound cycle following a Testosterone-only run.

Usage

Get a baseline blood panel before week 1 – Boldenone has a noticeable effect on haematocrit.
Inject both esters twice per week intramuscularly (e.g. Mon/Thu).
Start Oxandrolone only in week 7, split across 2 daily doses.
Keep caloric intake moderate (+200–300 kcal) – this stack is built for quality.
Check haematocrit in weeks 8 and 12 (Boldenone effect).
Due to the Undecylenate half-life, begin PCT only 3–4 weeks after the last injection.

Warnings

Contraindications

Do not use in cases of prostate or breast carcinoma, pregnancy, breastfeeding, if under 18 years of age, or with a history of polycythaemia. Boldenone markedly increases red blood cell production – avoid if you have a history of haematocrit problems.

Side Effects

Boldenone: elevated haematocrit and associated thrombosis risk, increased appetite, possible anxiety or restlessness in sensitive users. Oxandrolone: reduction in HDL cholesterol and mild hepatic stress (17α-alkylated). Testosterone: aromatisation, water retention, suppression.

Monitoring

Haematocrit and red blood cell count in weeks 8 and 12 – if values exceed 52 %, consider dose reduction or blood donation. Lipid panel in week 12 (Oxandrolone phase). Measure blood pressure yourself on a weekly basis.

PCT

Start PCT 3–4 weeks after the last injection due to the 14-day Undecylenate half-life: Tamoxifen 20 mg/day + Clomiphene 50 mg/day for 4 weeks. Starting too early is counterproductive – compound levels will still be suppressive.

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.

Boldenone Undecylenate 250mg/ml 10ml Vial by Hilma Biocare

Hilma Biocare Boldenone Undecylenate 250mg/ml is an injectable anabolic steroid formulated to serve as a pharmacologically distinct layer within structured multi-compound cycles, delivering 250mg of boldenone undecylenate per millilitre across a 10ml vial engineered for sustained synergistic integration. Its core advantage lies in complementing primary androgens — most notably testosterone esters and nandrolone — by contributing a separate anabolic stimulus through moderate aromatisation and erythropoietic drive, without replicating the pharmacological profile of the base compound. Quality is independently substantiated: each finished batch undergoes HPLC-confirmed potency verification and LAL-method endotoxin screening before release, anchored within a GMP-compliant production framework.
