Testosterone (TRT)
Testosterone replacement therapy (TRT) involves administering exogenous testosterone (via injections, gels, patches, or pellets) to raise or stabilize serum testosterone levels. Clinically, TRT is prescribed for confirmed hypogonadism and can improve libido, energy, muscle mass, bone density, and mood in some populations. However, TRT suppresses the hypothalamic–pituitary–testicular axis (HPTA) by design, reducing endogenous testosterone production and altering downstream hormone signaling.
In PFS/PSSD/PAS discussions, TRT is explored for different reasons than standard hypogonadism. Some individuals pursue TRT hoping that restoring androgen levels will overcome symptoms attributed to androgen disruption. Others discuss TRT as part of a “reset” attempt, where testosterone is used temporarily and then discontinued with a post-cycle therapy (PCT) to stimulate endogenous recovery. Importantly, these approaches are experimental in this context, and TRT does not directly address many of the hypothesized mechanisms discussed in these syndromes (e.g., altered androgen receptor signaling, neurosteroid/GABA dysregulation, or persistent gene-expression changes).

How to Interpret This Page
This page summarizes community anecdotes and informal observations, not medical evidence. “Improvement” means a person reported feeling better after an intervention; it does not prove the intervention caused the change or that it will apply to others. Outcomes are often influenced by multiple variables (time, stopping another trigger, dose changes, adjunct medications, PCT protocols, sleep/diet, and baseline health), and reporting bias is common. Some interventions described in improvement stories are also associated with flares or worsening in other reports.

Community Reports: Mixed Outcomes & Variable Risk Signal
Within PFS/PSSD/PAS communities, TRT is described with highly mixed outcomes. Some individuals report partial symptom improvement—often in physical energy, libido, or resilience—particularly when TRT begins after a prolonged low-testosterone period or when improvement coincides with stopping another destabilizing factor. A smaller subset describe improvement emerging after TRT discontinuation combined with a PCT, framing it as a possible “reset” rather than a benefit of sustained testosterone exposure.
At the same time, many report little to no improvement, and a substantial number describe feeling worse on TRT, especially at higher doses. Commonly reported downsides include increased anhedonia or emotional blunting, worsened genital numbness, irritability, anxiety, sleep disruption, or a sense that symptoms become more “flattened” despite normalized or high serum testosterone. This has led many to view TRT as potentially helpful for a subset symptomatically, but mechanistically incomplete—it can normalize hormone levels while not reliably restoring downstream androgen responsiveness, neurosteroid balance, or emotional/sexual function in these syndromes.
The practical risk signal is that TRT is a high-impact endocrine intervention with meaningful tradeoffs: it suppresses endogenous production, can affect fertility, and stopping it can introduce additional instability. In an already sensitized population, hormonal shifts and dose changes are often reported as destabilizing. For these reasons, TRT is commonly framed as a clinician-supervised, higher-stakes decision rather than a broadly applicable solution, and some individuals prioritize lower-dose approaches or avoid TRT entirely if it consistently worsens emotional or sexual symptoms.
Evidence Basis
Established endocrinology and clinical literature on testosterone replacement therapy and HPTA suppression; theoretical discussions around androgen receptor signaling and neurosteroid involvement; anecdotal community reports (online forums, self-reports).
No controlled studies demonstrate TRT as a treatment for PFS/PSSD/PAS-specific outcomes.
