Peptide options

Peptides are short amino acid chains that signal specific biological processes. More targeted than supplements but require more sophistication in sourcing and administration. All peptide use should be discussed with a provider — this section is informational. Each entry links to the full Whatstack peptide reference.

BPC-157

Why it matters for perimenopause: As estrogen declines, connective tissue becomes more vulnerable. Joint pain, tendon issues, and gut disturbance increase sharply. BPC-157 promotes angiogenesis (new blood vessel formation), upregulates growth hormone receptors locally, and has anti-inflammatory effects via the nitric oxide system. It also supports gut lining integrity — relevant if GI issues appear or if using a GLP-1 medication.
What you get: Accelerated joint and tendon healing

Reduced systemic inflammation

Gut lining protection and repair

May improve cognitive function (gut-brain axis)

Neurotransmitter regulation (serotonin, dopamine pathways)
Evidence: ●●●●● Moderate — strong preclinical, limited human RCTs
Extensive animal model data. Human clinical evidence is still emerging. Clinical practitioner experience is overwhelmingly positive. Source from third-party tested, COA-verified suppliers.
Timeline: Healing effects: 1–2 weeks. Gut improvement: 2–4 weeks. Run 4–8 week cycles.
Pairs with: TB-500 (systemic tissue repair — complementary mechanism). Strength training (accelerates recovery).

Sermorelin / CJC-1295 / Ipamorelin

Why it matters for perimenopause: Growth hormone production drops alongside estrogen. This contributes to muscle loss, fat gain, skin thinning, poor sleep, and slower recovery. GH secretagogues restore more youthful GH pulsatility — particularly the overnight pulse that drives deep sleep, tissue repair, and fat metabolism.
What you get: Improved sleep quality (particularly deep sleep)

Better body composition (muscle preservation, fat reduction)

Faster recovery from exercise

Skin quality improvement

Enhanced energy and vitality
Options: Sermorelin — strongest regulatory standing; FDA-approved for GH deficiency. Shorter half-life.

CJC-1295 No DAC + Ipamorelin — the classic combination. GHRH + GHRP synergy delivers a clean physiologic pulse.

Ipamorelin alone — the cleanest GHRP, minimal cortisol/prolactin bump.
Evidence: ●●●●● Moderate — sermorelin is FDA-approved (for GH deficiency)
Sermorelin has the strongest regulatory standing. Ipamorelin has a better side-effect profile but less formal clinical data. Administer at bedtime on an empty stomach (food blunts GH secretion).
Timeline: Sleep improvement: 1–2 weeks. Body composition: 4–8 weeks. Full effects: 3–6 months. Monitor IGF-1 levels.

PT-141 (Bremelanotide)

Why it matters for perimenopause: Declining estrogen and testosterone reduce libido in many women during perimenopause. PT-141 activates melanocortin receptors in the brain that modulate sexual arousal. It works on desire, not just function — a critical distinction from medications that only address blood flow.
Evidence: ●●●●● Strong — FDA-approved (premenopause); off-label in peri
FDA-approved as Vyleesi for HSDD in premenopausal women. Typical dose: 1.75mg subcutaneous, 45 minutes before anticipated activity. Nausea is the most common side effect — starts mild and typically resolves with subsequent use. Maximum 8 doses per month.
Timeline: Onset: 30–60 minutes. Duration: up to 12 hours. Used as-needed, not daily.
