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.

Semax

Synthetic ACTH Analog | Nootropic & Neuroprotective Peptide

Rapidly increases BDNF levels, modulates dopaminergic and serotonergic systems, and achieves direct brain delivery through olfactory transport with 0.093% blood-brain barrier penetration (vs 0.

Shared Safety Flags

Frequently Asked Questions

Can I take LGD-4033 with Semax?

Yes, but with caution. Both LGD-4033 and Semax can raise blood pressure. Monitor BP regularly and consider adding cardiovascular support (cardarine, telmisartan, or similar). Regular monitoring is advised.

Is LGD-4033 and Semax safe together?

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

What are the interactions between LGD-4033 and Semax?

Both LGD-4033 and Semax can raise blood pressure. Monitor BP regularly and consider adding cardiovascular support (cardarine, telmisartan, or similar). This assessment has 51% confidence and is inferred from pharmacological mechanism analysis.

How should I time LGD-4033 and Semax?

LGD-4033 has a half-life of ~24-36 hours and Semax has a half-life of 0.5-2 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.

Side effects

Will tamoxifen cause hot flashes and other side effects during PCT?

Yes—hot flashes are common during the first 2-4 weeks as your estrogen and testosterone levels normalize. These typically resolve once hormones stabilize. Other common side effects include mood swings and mild nausea. These are temporary PCT-phase effects that disappear once recovery is complete.
