1.HRT Protocols: 750–1000 mg every 10–12 weeks (Nebido). Bodybuilders often modify this:
●Bulking: 500–750 mg every 3–4 weeks to maintain supraphysiological levels.
●Cruising: 250–500 mg monthly to sustain baseline testosterone.
2.Oral TU (Andriol): 120–240 mg daily, split into doses with fatty meals for absorption. Limited utility for mass gain due to low bioavailability.
Injection Protocol
●Use 23–25-gauge needles; glutes or ventrogluteals accommodate larger volumes (3–4 mL).
●Warm oil to reduce viscosity and prevent post-injection pain (PIP).
