Compound Profiles

P21

P021 | CNTF-Derived Neurogenic Peptide

P21 operates through multiple pathways: it inhibits leukemia inhibitory factor (LIF) signaling, removing a key roadblock to neurogenesis and shifting the brain toward a more embryologic state favoring neuron growth. It increases brain-derived neurotrophic factor (BDNF) expression and activates the BDNF/TrkB/PI3-K/AKT/GSK3β pathway.

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.

Research context

Read sources and limitations before applying a claim.

Research Indications

Superdrol produces substantial lean mass gains in compressed timeframes, typically 8-12 pounds of lean tissue in a 3-4 week cycle. These gains are notably dry and devoid of water retention due to the absence of estrogenic activity. Widely reported to produce some of the most dramatic strength increases of any oral steroid. Users commonly report significant personal records within the first 2-3 weeks of use. As a non-aromatizing DHT derivative, Superdrol promotes a dense, dry, and grainy muscular appearance without subcutaneous water retention. Often used in the final weeks before a bodybuilding competition.
