Pellets vs Other Methods — What Research Shows

Hormone Stability & Pharmacokinetics

Pellets — continuous release

• Subcutaneous pellets provide steady time-released dosing over months, supporting more stable serum levels and adherence.

• Continuous delivery is designed to reduce the “peaks and valleys” seen with short-acting methods.

Oral / injections — peak-trough pattern

• Pharmacokinetic data show oral or bolus dosing produces rapid peaks followed by decline in hormone levels.
  Stable exposure is one reason some clinicians use pellets for symptom stability, adherence, and consistent physiologic signaling.

Symptom Improvement — Comparative Studies

Observational comparative research (pellet vs transdermal/lotion):

• Pellet therapy showed greater improvement in vasomotor symptoms, sleep, fatigue, libido, and vaginal dryness compared with lotion therapy.

• Larger increases in serum testosterone and greater FSH reduction were observed in pellet users.

• Higher continuation rates were reported with pellets vs transdermal therapy (76% vs 59%).

Route of Administration Matters

Large reviews show:

• Route (oral vs transdermal vs other) significantly affects risk profile and physiology.

• Transdermal estrogen is associated with lower venous thromboembolism risk compared with oral therapy.

• Benefits and risks of hormone therapy vary by type, dose, and route, not age alone. :
  Delivery method is a major determinant of outcomes — supporting individualized treatment selection.

Comparative delivery study (Pellet vs Transdermal)

Rossi R. et al. (2021 / 2025 update)
Comparison of two delivery methods of bioidentical hormone replacement therapy.

• Design: Comparative observational study

• Findings: Pellet therapy showed significantly greater improvement in vasomotor symptoms (hot flashes), sleep, libido, vaginal dryness, fatigue, and other menopausal symptoms vs transdermal therapy, without increased adverse events.
  

Testosterone pellet therapy clinical study (men)

Kresch E. et al. (2023)
Efficacy and safety outcomes of a compounded testosterone pellet.

• Design: Prospective randomized single-blinded study

• Findings: Pellet testosterone produced comparable serum testosterone levels and similar adverse event rates, supporting pellets as an effective long-term testosterone therapy option.
  

Critical review of hormone pellets

Wender MCO. (2025)
Compounded hormonal pellets: a critical review of current evidence.

• Finding: Evidence for testosterone pellets in women is largely observational, with symptom improvement reported but methodological limitations noted.
  

• Safety / guideline consensus (ACOG)

ACOG Clinical Consensus (2023)
Compounded bioidentical menopausal hormone therapy.

• Finding: High-quality data on compounded bioidentical hormone therapy (including pellets) remain limited; decisions should involve shared decision-making and counseling on risks/benefits.
  

Recent review literature reports that available scientific evidence on subdermal hormone pellets is often low quality or heterogeneous, highlighting need for more randomized trials.

Hormone Therapy Evidence

Oral vs Transdermal systematic review

Goldštajn MŠ. et al. (2022)
Effects of transdermal versus oral hormone replacement therapy.

• Design: Systematic review of RCTs + observational studies

• Findings: Route of administration affects risk profile; strongest evidence shows higher VTE risk with oral vs transdermal therapy.
  

Randomized / cohort HRT body composition study

Partly randomized cohort of early postmenopausal women showed hormone therapy influences body composition and weight distribution.

Meta-analysis of RCTs (muscle mass)

Systematic review of 12 randomized trials evaluating estrogen-based hormone therapy found mixed effects on lean body mass, demonstrating variable physiologic impact across methods.
