1. Overview

Humanin is a 24-amino-acid mitochondrial-derived peptide (MDP) encoded by an open reading frame in the mitochondrial 16S ribosomal RNA region (MT-RNR2). It was first reported by Hashimoto et al. (Nishimoto laboratory) in PNAS 98:6336 (2001), isolated from surviving neurons of Alzheimer's-disease brain tissue — "Endogenous Rescue Factor Abolishing Neuronal Cell Death." The metabolic and cytoprotective research framework around humanin was subsequently pioneered by the Pinchas Cohen lab (USC Leonard Davis School of Gerontology), which characterized its roles in insulin sensitivity, glucose metabolism, and longevity — including the finding that circulating humanin levels are elevated in centenarians and long-lived individuals.

Purpose: cytoprotection and anti-apoptotic signaling; metabolic regulation and insulin sensitivity; neuroprotection; studied in the longevity niche rather than as a weight-loss agent per se (it sits in this category as a mitochondrial/metabolic peptide).

Known analogs:

• HNG — [Gly14]-Humanin, the S14G substitution; far more potent in preclinical models; most community "humanin" dosing lore actually refers to the analog level.
• HNGF6A — an HNG derivative engineered for further stability; preclinical.
• S14G-humanin = HNG.

2026 status: research chemical only. No branded product, no approved drug, no clinical-grade formulation exists for the native peptide.

2. Social standing — platform pulse

Overall pulse: quiet. Humanin is a second-tier mitochondrial peptide in community discussion — it lives in the shadow of MOTS-c, which dominates the "mitochondrial peptide" conversation (energy, metabolism, exercise-mimetic framing). Humanin is discussed in deeper biohacker/longevity circles with a neuroprotection and cellular-resilience framing: stacked with MOTS-c, SS-31, 5-amino-1MQ, and small humanin-like peptides (SHLPs) in mitochondrial support stacks, and cited for the centenarian/longevity association.

Threads (strongest layer):

• @natashainca (Natasha Wiscombe, "Lifestyle Design & Healthspan," verified) — October 2024 post listing her favorite mitochondria-supporting peptides kept "on rotation for myself & clients" after 7 years of peptide use: MOTS-c, SS-31, Humanin, 5-amino-1MQ, BPC-157, TB4 Active Frag (Ac-SDKP), SHLPs, DSIP, and others. Context: practitioner-style rotation post, 14 likes / 2 replies / 2 quotes. This is the clearest public owner-practitioner endorsement found: humanin as a standing rotation peptide, not a one-off experiment.
• @peptidou.jp (Japanese peptide-information account) — notes that humanin comes up in anti-aging contexts, but the actual body of research is basic research (cell models) and correlational diet-pattern studies — not human administration trials; explicitly flags it as unapproved, therefore outside Japan's drug adverse-reaction relief system. Context: skepticism/education post pushing back on anti-aging hype.

Facebook Groups (highest-signal source normally; thin here):

• Searched "humanin" posts in "Peptides / Aminos / Nootropics / Biohacking / Longevity" (~1,000 members) and "Peptide Beginners Guide | Education & Support" (~1,000 members) — zero results in both. Related groups found during search: "Multiple Sclerosis Peptide Education & Resources" (mitochondrial support framing). The empty result is itself a signal: humanin does not generate active group discussion at the level MOTS-c or GLP-1s do.

Instagram:

• No confirmed named IG owner posts for humanin found. The Sunday Times (April 2026) reported peptides broadly being marketed on Instagram/TikTok/Telegram, but no humanin-specific IG account or viral post surfaced. IG layer: unconfirmed.

Viral moments: none identified. No documented viral humanin post, protocol video, or controversy moment found across the platforms searched.

Praise (community-reported, anecdotal):

• A Reddit-thread summary (via Jay Campbell's compilation) reports users trialing "2 mg every other day" and noting improved sleep quality in someone who usually woke 1–3 times per night.
• SteroidWiki's community-dosage compilation reports "1 mg twice a day" as commonly used given the short half-life, associated by users with a "sense of calm and wellness."
• Ben Greenfield's published 8-week self-experiment course used much lower microgram-level dosing (~100 µg), cited by PeptideDeck as a reference protocol.

Complaints (community-reported):

• Very short half-life (~30 minutes for the native peptide) — frequent dosing (twice daily) is reported as the main practical drawback.
• No established protocol: community doses scatter from 25–50 mcg/day (HNG analog) to 5 mg every 4–5 days, creating confusion about whether a vial contains native humanin or the far more potent analog.
• High cost per milligram at some vendors relative to how little human data exists.

3. Social validation — Tier 3 (weak)

Tier: Tier 3 — single-platform (Threads), flag WEAK.

Verdict: Only the Threads layer produced named, attributable sources. FB Groups — normally the highest-signal layer — are silent on humanin. No IG owner content confirmed. Per the tier contract this is Tier 3 and should be treated as weak validation.

4. Key specs

5. Pricing

There is no brand MSRP — no branded/approved product exists. All prices below are grey-market research vendors, observed 2026-09-20 via web search. Crawl dates are noted where the search index provided them; treat as approximate.

Facebook Marketplace: searched "humanin peptide" 2026-09-20 — no listings found. No observed used-market range exists.

Street-price range: roughly $48–$295 per 5–10 mg vial across research vendors (wide spread; mg-normalized prices vary ~3–8×). One vendor page (Peptide Pros, crawled 2026-09-19) claims "Humanin is one of our top sellers" — vendor marketing claim, unverified by any third party.

6. What is included / what else is needed

• Included: lyophilized peptide powder in a sealed glass vial (typically 5 mg or 10 mg; sterile closure).
• Needed: bacteriostatic water for reconstitution; insulin syringes (U-100); alcohol pads; refrigeration (2–8 °C) for the lyophilized vial. One clinic-style kit (Celia Health "Longevity" protocol) bundles: 1 vial (5 mg/4 mL), 20 × 29/30G subq needles, 5 mL + 10 mL syringes, 25G needle, 10 mL bacteriostatic water, reconstitution/administration instructions (10-day cycle at 500 mcg/day subq). Reconstitution handling per community/vendor guidance: inject diluent slowly down the vial wall, swirl — do not shake; refrigerate after reconstitution.

7. Support reality

• Peptide Partners (from their product page, observed 2026-09-20): order cancellations with full refund available before shipment; shipped orders cannot be cancelled or refunded; damaged/incorrect goods require photos of outer/inner packaging and agent labels emailed to support within 48 hours of carrier delivery. CoAs published per current lot.
• Peptide Pros (from their product page): claims "Guaranteed Delivery" and replacement of products that "do not perform as expected in your research" — vendor's own claim, not independently verified.
• Community reports on humanin-specific vendor support: none found. No Reddit/FB/Threads complaints or praise about humanin vendor returns or customer service surfaced in this research pass. Support reputation for humanin vendors: UNVERIFIED/thin — buyers rely on each vendor's stated policy.

8. Community verdict

Humanin is a niche mitochondrial peptide with a real but narrow following in longevity and biohacker circles — a practitioner's rotation-list item, not a mainstream peptide. Its preclinical science (cytoprotection, insulin sensitivity, centenarian association) is genuinely interesting, but there are no human trials of the native peptide, dosing is scattered across an order of magnitude, the ~30-minute half-life makes protocols impractical, and community validation is thin (Tier 3). Anyone considering it is buying a research chemical on the basis of animal and cell studies plus practitioner anecdote.

9. Regulatory & safety status

• Not approved by the FDA, EMA, or any medicines regulator for any use. Sold strictly as a "research chemical — not for human or veterinary use" by every vendor surveyed.
• No human safety profile exists. No published human clinical trials; no established dose; no systematic safety data in humans — stated plainly.
• Preclinical safety: studied only in cell and animal models (including HNG/HNGF6A analog work). Absence of human adverse-event data is absence of data, not evidence of safety.
• Unapproved injectable research peptides carry the standard risks: uncertain purity and sterility, mislabeling (native vs. far-more-potent HNG analog in an unlabeled vial — flagged by PeptideDeck as a real dosing hazard), contamination, and no legal recourse or adverse-event compensation. Plain language: this is an experimental substance with no human testing; using it means accepting unknown risks.

10. Missing-image views + UNVERIFIED points log

Photos: 1 verified real photo collected — img/humanin-hero.jpg (Peptide Pros Humanin 5 mg vendor vial product photo, verified photographic image, JPEG, 2026-09-20; source: https://www.peptidepros.net/product/humanin-5mg/). Rejected as synthetic/3D-render-looking: TK Peptides labeled vial render (tk-peptides.com), Nexus Laboratory vial render (nexuslaboratory.org, path literally /products/3d/), Kensington Labs two-vial render (kensingtonlabs.co.uk), Peptide Forge neon cinematic render (peptideforgelabs.com), NextLevel Pharm label-composite graphic (nextlevelpharm.com), Peptide Partners packaging-composite render (peptide.partners). simplepeptidesllc.com's vial photo blocked automated download (server refused connection). Missing-image views: side, rear, top (alternate angle), detail, owner-in-use, scale, box/accessories — no verified real photos found for these; owner-in-use and scale photography does not appear to exist publicly for humanin.

UNVERIFIED points:

1. Whether any given vendor's "Humanin" vial contains the native 24-aa peptide or the S14G/HNG analog — labels are inconsistent across vendors (one page lists the sequence with a terminal variant); no independent verification.
2. Peptide Pros' claim that humanin is "one of our top sellers" — vendor marketing, unverified.
3. Community dose ranges — all anecdotal, none from trials; the "sense of calm and wellness" and sleep-quality reports are single-source anecdotes.
4. Purity/CoA claims on vendor pages (e.g., "≥99% HPLC, third-party tested") — taken from vendor pages, not independently lab-verified by this research.
5. social.search cross-platform meta-search timed out on 2026-09-20 (infrastructure), so IG/FB-wide coverage is incomplete; IG layer remains unconfirmed.
6. Celia Health's 10-day, 500 mcg/day "Longevity" protocol is a vendor/clinic kit insert, not a clinical protocol.
7. Exact date-stamps on some vendor prices rely on search-index crawl dates, which are approximate — stale entries flagged in the table.
8. "Elevated humanin in centenarians" association is from published cohort research (Cohen lab) — correlation, not evidence that supplementation extends healthspan.
