Bodies change. Find the peptides relevant to where yours is now.
Perimenopause, menopause, andropause, aging in general, post-injury recovery, burnout, postpartum, cognitive shifts, fertility planning, sexual dysfunction — transitions where the body changes and people start looking for tools. Each stage below is editorially mapped to the peptides in our library that have documented or mechanistically-clear relevance.
Editorial posture: we don’t pad these lists. If a stage has only one peptide that’s genuinely relevant, we list one. If a stage is best served by non-peptide interventions (HRT, TRT, lifestyle, clinical evaluation), we say so up front.
Perimenopause
7 peptidesThe transition years before menopause — hormones fluctuating, cycle irregular, sleep and mood shifting. Typically late 30s to mid-50s.
ExploreMenopause
9 peptidesPostmenopausal years — sustained low estrogen, accelerated bone and muscle loss, altered metabolism. Typically 50+.
ExploreAndropause (aging male)
7 peptidesAge-related testosterone decline and HPG-axis softening in men, typically 40+. Symptoms span libido, mood, body composition, recovery.
ExploreGeneral aging (40+)
12 peptidesWhole-system aging — declining mitochondrial function, telomere shortening, sarcopenia, slowed recovery, gradual cognitive shifts.
ExplorePost-injury recovery
6 peptidesTissue healing after acute injury — joints, tendons, ligaments, muscle tears, post-surgical recovery, chronic non-healing wounds.
ExploreBurnout / chronic fatigue / asthenia
7 peptidesPersistent low energy, motivation collapse, post-stress exhaustion — not explained by anemia or thyroid dysfunction.
ExploreFertility planning
4 peptidesOptimizing reproductive health ahead of conception attempts — applies to both partners.
ExplorePostpartum
1 peptideRecovery from pregnancy and childbirth — mood, energy, body composition, sleep deprivation, lactation considerations.
ExploreCognitive decline / brain fog
6 peptidesSubjective cognitive shifts — slower processing, word retrieval issues, memory lapses — typically age-related but sometimes post-illness or post-stress.
ExploreSexual dysfunction (libido, arousal)
3 peptidesReduced libido or arousal, independent of testosterone levels — applies to both sexes.

A note on what’s NOT on this page
Adolescence, pregnancy, acute illness, terminal-stage care, and pediatric conditions are deliberately not included. The library’s evidence base for peptides in these contexts is thin-to-absent, and the safety floor for "first do no harm" is higher than community use warrants. Users in those situations are better served by a clinician familiar with their specific context, not by a peptide library.
