Compound Profiles

Ketoconazole

Antifungal | Topical Anti-Androgen for Hair Loss

Ketoconazole works through multiple pathways relevant to hair loss. As an azole antifungal, it inhibits the enzyme lanosterol 14-alpha-demethylase, disrupting ergosterol synthesis and killing Malassezia fungi that colonize the scalp and contribute to inflammation and seborrheic dermatitis.

Testosterone

Anabolic-Androgenic Steroid | Primary Male Sex Hormone

Testosterone exerts its effects primarily through binding to the intracellular androgen receptor (AR), forming a hormone-receptor complex that translocates to the nucleus and modulates gene transcription. This drives protein synthesis in skeletal muscle (anabolic effect), stimulates erythropoietin production in the kidneys to increase red blood cell mass, promotes osteoblast activity and bone mineral density, and regulates libido and cognitive function.

Shared Safety Flags

Frequently Asked Questions

Can I take Ketoconazole with Testosterone?

Yes, but with caution. Both Ketoconazole and Testosterone carry androgenic activity. Additive androgenic load increases risk of acne, hair loss, and prostate effects. Monitor for dose-dependent side effects. Regular monitoring is advised.

Is Ketoconazole and Testosterone safe together?

Based on pharmacological analysis, this combination is considered monitor. However, shared safety flags include: androgenic. Monitor accordingly.

What are the interactions between Ketoconazole and Testosterone?

Both Ketoconazole and Testosterone carry androgenic activity. Additive androgenic load increases risk of acne, hair loss, and prostate effects. Monitor for dose-dependent side effects. This assessment has 60% confidence and is inferred from pharmacological mechanism analysis.

How should I time Ketoconazole and Testosterone?

Ketoconazole has a half-life of Topical application stays local with minimal systemic absorption and Testosterone has a half-life of ~8 days (cypionate). No specific timing requirements identified for this combination, but separating administration can help monitor individual effects.

This interaction analysis is compiled from research literature and pharmacological mechanism data. This assessment is inferred from known mechanisms and may not reflect all real-world outcomes. Always consult a healthcare professional before combining compounds.

Research Indications

Noopept's best-established effect is enhancement of memory consolidation and retrieval. Animal studies consistently demonstrate improved performance on spatial memory, passive avoidance, and novel object recognition tasks. Human studies in patients with mild cognitive impairment and organic brain disorders show improvements in memory scores and attentional capacity. Demonstrated neuroprotective activity in multiple models of neuronal injury including oxidative stress, amyloid-beta toxicity, and glutamate excitotoxicity. The upregulation of BDNF and NGF provides trophic support to vulnerable neuronal populations, which may slow or prevent neurodegeneration. Users commonly report improved clarity of thought and sustained attention. While less studied than memory effects, the modulation of glutamatergic signaling and downstream cholinergic enhancement likely contribute to improved attentional performance. Approved in Russia for cognitive deficits following traumatic brain injury. Clinical trials demonstrated improvements in memory, attention, and emotional stability in patients recovering from cerebral trauma. Approved for cognitive decline associated with cerebrovascular insufficiency. Patients with chronic cerebrovascular disease showed improvements in cognitive test scores and reduction in associated emotional disturbances including anxiety and irritability. Preclinical evidence suggests potential benefits through NGF/BDNF upregulation and inhibition of amyloid-beta aggregation and neurotoxicity. Not yet tested in rigorous clinical trials for Alzheimer's specifically, but the mechanistic rationale is strong. An anxiolytic effect has been observed in both animal models and human clinical use at standard nootropic doses. Unlike benzodiazepines, the anxiolytic effect does not come with sedation or cognitive impairment, making it a potentially useful secondary benefit.

How much FOXO4-DRI should a human dose based on mouse studies?

The original 2017 mouse study used 5 mg/kg IP, 3 times on alternate days. For a 60kg human, this translates to approximately 25mg per dose, administered as 3 doses every other day (75-100mg total per cycle). However, human pharmacokinetics differ significantly from mice, making these translations speculative.

Dosing Protocols

Ezetimibe is administered exclusively by the oral route as a 10 mg tablet taken once daily. It can be taken with or without food, at any time of day, though consistent timing is recommended for adherence. The drug does not require dose titration, as the 10 mg dose is the only approved strength and has been shown to provide the optimal balance of efficacy and tolerability. Ezetimibe is extensively glucuronidated in the small intestine and liver, and the active parent compound and its glucuronide metabolite undergo enterohepatic recirculation, contributing to the long effective half-life. Standard Lipid Management 10 mg/day Once daily Oral, with or without food On-Cycle Lipid Support (AAS Users) Once daily, throughout cycle and into PCT Combination with Statin 10 mg/day ezetimibe + statin of choice Once daily (ezetimibe can be taken same time as statin or separately) Oral
