Injectable Steroids Dosage & Cycle Guide: Beginner to Advanced

Introduction: Why Dosage Matters More Than Compound Choice

The most common mistake in injectable steroid use is not choosing the wrong compound — it is using the wrong dose for the wrong duration. Excess dose beyond your body’s androgen receptor saturation threshold does not produce more muscle; it produces more side effects. This guide provides evidence-informed dosage frameworks for the most widely used injectable steroids across beginner, intermediate, and advanced experience levels.

General Dosage Principles

• Start low, escalate cautiously. Your body has never processed a given dose before your first cycle. Start conservative.
• More is not always better. Side effects scale with dose; results plateau well before maximum tolerated doses.
• Cycle length and ester clearance must be matched. Short cycles with long esters waste weeks waiting for blood levels to stabilise.
• Bloodwork is non-negotiable. No dosage guideline replaces individual blood monitoring.

Testosterone Enanthate / Cypionate Dosage

Experience Level	Weekly Dose	Cycle Length	Injection Frequency
Beginner	300–400 mg	10–12 weeks	2×/week
Intermediate	400–600 mg	12–16 weeks	2×/week
Advanced	600–800 mg	16–20 weeks	2×/week or EOD

Nandrolone Decanoate (Deca) Dosage

Deca should always be run alongside testosterone at minimum. The classic ratio is testosterone:Deca = 2:1 (e.g., 400 mg Test / 200 mg Deca). This prevents the prolactin-mediated sexual dysfunction commonly associated with nandrolone monotherapy.

Experience Level	Deca Weekly Dose	Cycle Length
Intermediate	200–400 mg	12–16 weeks
Advanced	400–600 mg	16–20 weeks

Boldenone (Equipoise) Dosage

Equipoise’s long undecylenate ester requires a minimum 16-week cycle to fully stabilise blood levels and see peak effects. Shorter cycles are inefficient.

Experience Level	Weekly Dose	Cycle Length
Intermediate	300–500 mg	16 weeks
Advanced	500–700 mg	16–20 weeks

Trenbolone Dosage

Trenbolone is not a beginner compound. Its potency (5× androgenic activity of testosterone) and unique side effect profile (night sweats, insomnia, cardiovascular stress, prolactin activity) demand experience managing multiple compounds. Only advanced users with several cycles completed should consider trenbolone.

Form	Weekly Dose	Injection Freq.	Cycle Length
Acetate	200–400 mg	EOD	8–12 weeks
Enanthate	200–400 mg	2×/week	10–14 weeks

Masteron Dosage

Masteron (drostanolone) delivers hardening and anti-estrogenic effects, making it ideal for cutting and contest prep phases where body fat is already low.

Form	Weekly Dose	Injection Freq.
Propionate	300–500 mg	EOD
Enanthate	400–600 mg	2×/week

Sample Beginner Bulking Cycle (12 Weeks)

• Weeks 1–12: Testosterone Enanthate 400 mg/week (200 mg Monday/Thursday)
• Weeks 1–12: Anastrozole 0.25 mg EOD (adjust based on estrogen symptoms and bloodwork)
• Weeks 14–17: PCT (Nolvadex 40/40/20/20 mg/day)

Sample Intermediate Bulking Cycle (16 Weeks)

• Weeks 1–16: Testosterone Enanthate 500 mg/week
• Weeks 1–16: Nandrolone Decanoate 300 mg/week
• Weeks 1–16: Anastrozole 0.25–0.5 mg EOD
• Weeks 16–20: Cabergoline 0.25 mg 2×/week (nandrolone prolactin management)
• Weeks 18–21: PCT (Nolvadex + Clomid protocol)

PCT After Injectable Cycles

All injectable steroids suppress endogenous testosterone production. PCT timing depends on the half-life of the compounds used. For long-ester cycles (enanthate, cypionate, decanoate), wait 2 weeks after the last injection before starting PCT to allow hormone levels to drop sufficiently for SERMs to work effectively.
