Research stacks
Stacks are peptide combinations that appear together in the research literature. Each entry lists component peptides, the reported purpose, typical duration, and cycling notes. Nothing here is a treatment protocol.
Cognitive Stack
foundational
Neuropeptide research — pairing the anxiolytic tuftsin-derived Selank with the neurotrophic ACTH-fragment Semax, the two most commonly discussed peptides in the Russian nootropic research tradition.
GH Pulse Stack
intermediate
Growth-hormone axis stimulation research — a GHRH analogue combined with a selective ghrelin-receptor agonist to engage two independent GH-release pathways.
Injury Recovery Foundation
foundational
Tissue-repair research (tendon, ligament, muscle, gut mucosa) — combining a short-acting locally-active peptide with a longer-acting systemic one.
Longevity Foundation
intermediate
Cellular energetics and senescence research — pairing a mitochondrial-derived peptide with a pineal tetrapeptide and NAD+ precursor availability, three axes commonly discussed together in the longevity research literature.
Metabolic Research Stack
advanced
GLP-1 receptor engagement for metabolic-endpoint research — semaglutide as the reference agonist, with tirzepatide discussed as a dual GLP-1/GIP comparator once the profile is added.
Sexual Health Research Stack
foundational
Melanocortin sexual-health research — using PT-141 as the primary reference peptide with notes on the non-selective precursor melanotan-II.
Skin & Repair Stack
intermediate
Skin-remodelling and wound-repair research — combining a copper tripeptide characterised in dermatology models with a pentadecapeptide characterised in tissue-repair models.
Sleep Research Stack
foundational
Sleep architecture and nighttime GH-pulse research — pairing the pineal-linked DSIP with a short-acting GHRH analog administered at bedtime.
