Compound Profiles

LGD-4033

Selective Androgen Receptor Modulator | Lean Mass

LGD-4033 binds to the androgen receptor with high affinity (Ki of approximately 1 nM), functioning as a potent and selective agonist in muscle and bone tissue. Like other SARMs, its tissue selectivity is mediated by differential cofactor recruitment: upon binding to the AR, LGD-4033 induces a receptor conformation that preferentially recruits coactivators expressed in skeletal muscle and bone, while showing minimal agonist activity in androgen-sensitive tissues such as the prostate and skin.

Rapamycin

mTOR Inhibitor | Longevity & Immunosuppression

Rapamycin exerts its effects by binding to the intracellular protein FKBP12, forming a complex that directly and specifically inhibits mechanistic target of rapamycin complex 1 (mTORC1). mTORC1 is a master nutrient-sensing kinase that integrates signals from growth factors, amino acids, energy status, and stress to regulate cell growth, proliferation, and metabolism.

Shared Safety Flags

Frequently Asked Questions

Can I take LGD-4033 with Rapamycin?

Yes, but with caution. Both LGD-4033 and Rapamycin negatively affect lipid profiles. Combined use may significantly worsen HDL/LDL ratios. Include lipid support and get bloodwork mid-cycle. Regular monitoring is advised.

Is LGD-4033 and Rapamycin safe together?

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

What are the interactions between LGD-4033 and Rapamycin?

Both LGD-4033 and Rapamycin negatively affect lipid profiles. Combined use may significantly worsen HDL/LDL ratios. Include lipid support and get bloodwork mid-cycle. This assessment has 47% confidence and is inferred from pharmacological mechanism analysis.

How should I time LGD-4033 and Rapamycin?

LGD-4033 has a half-life of ~24-36 hours and Rapamycin has a half-life of ~62 hours. 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.

Join others researching Telmisartan — share findings, ask questions, and learn from real experiences Telmisartan is an angiotensin II receptor blocker (ARB) originally developed for the treatment of hypertension and cardiovascular risk reduction. FDA-approved since 1998 and marketed as Micardis, it has become the preferred ARB among performance-enhancing drug users and anabolic steroid communities due to its long half-life, strong evidence for organ protection, and unique partial PPAR-gamma agonist activity. Unlike other ARBs, telmisartan activates peroxisome proliferator-activated receptor gamma (PPAR-gamma) at clinically relevant doses, conferring metabolic benefits that extend beyond blood pressure reduction. Anabolic androgenic steroids (AAS) are well-documented to elevate blood pressure, promote left ventricular hypertrophy, accelerate atherosclerosis, and impair renal function -- making proactive cardiovascular protection an essential component of harm reduction. Telmisartan addresses these concerns with once-daily dosing, 24-hour blood pressure coverage, and a favorable side effect profile that does not impair exercise performance or recovery. Telmisartan selectively blocks the angiotensin II type 1 (AT1) receptor, preventing angiotensin II from exerting its vasoconstrictive, aldosterone-secreting, and pro-fibrotic effects. By antagonizing AT1, telmisartan lowers systemic vascular resistance and blood pressure while simultaneously reducing pathological cardiac and vascular remodeling. This is particularly relevant for AAS users, where supraphysiological androgen levels stimulate the renin-angiotensin-aldosterone system (RAAS) and promote myocardial fibrosis and left ventricular hypertrophy. Telmisartan also has the longest half-life of any ARB (approximately 24 hours), providing consistent receptor blockade throughout the dosing interval. Its unique partial agonism of PPAR-gamma -- a nuclear receptor involved in glucose and lipid metabolism -- distinguishes it from other ARBs. PPAR-gamma activation enhances insulin sensitivity, improves adiponectin secretion, reduces visceral fat accumulation, and exerts anti-inflammatory effects. Additionally, telmisartan demonstrates nephroprotective properties by reducing intraglomerular pressure and proteinuria, and has been shown in the ONTARGET trial to provide cardiovascular protection comparable to the ACE inhibitor ramipril in high-risk patients.

Join others researching Trazodone — share findings, ask questions, and learn from real experiences Trazodone is a serotonin antagonist and reuptake inhibitor (SARI) that was originally approved by the FDA in 1981 for the treatment of major depressive disorder. However, its clinical use has shifted dramatically over the decades. Today, trazodone is prescribed almost exclusively at low doses as a sleep aid rather than as an antidepressant, making it one of the most commonly prescribed medications for insomnia in the United States. Its popularity stems from the fact that it is non-habit-forming, does not carry the dependence risk associated with benzodiazepines or Z-drugs, and can be used long-term without tolerance development. Trazodone has become particularly well-known in the bodybuilding and performance-enhancement community as a go-to solution for managing insomnia caused by trenbolone and other 19-nortestosterone derivatives, which are notorious for disrupting sleep architecture. Unlike many sleep medications, trazodone actually improves slow-wave sleep (deep sleep) rather than simply inducing sedation, which makes it especially valuable for recovery-focused athletes. Trazodone's sleep-promoting effects arise from a combination of pharmacological actions across multiple receptor systems. At low doses (25-100 mg), the dominant mechanism is potent antagonism of 5-HT2A serotonin receptors, which promotes slow-wave sleep and reduces sleep latency. Trazodone also blocks histamine H1 receptors, contributing to its sedative properties, and antagonizes alpha-1 adrenergic receptors, which produces additional drowsiness and accounts for the orthostatic hypotension sometimes observed. At higher doses used for depression (150-400 mg), serotonin reuptake inhibition (SRI) becomes more relevant, increasing serotonergic tone in a manner similar to SSRIs but with a distinct receptor profile. The compound is metabolized primarily by CYP3A4 to its active metabolite meta-chlorophenylpiperazine (mCPP), which has serotonin agonist properties. The dose-dependent shift in pharmacological profile explains why trazodone is sedating at low doses but can be activating or cause more typical serotonergic side effects at antidepressant doses.

Dosing Protocols

Dapoxetine is administered orally as a film-coated tablet, taken on-demand 1-3 hours before anticipated sexual activity. It can be taken with or without food, though taking it with food may slightly delay peak plasma concentration. It should be swallowed whole with a full glass of water. Alcohol should be avoided as it may increase the risk of dizziness and syncope. PE treatment (starting dose) 30mg As needed, 1-3 hours before sexual activity Oral PE treatment (increased dose) 60mg
