DSIP (Delta Sleep-Inducing Peptide): Does It Help Sleep?
Named for what it was supposed to do. Decades later the human sleep evidence for DSIP remains thin, small, and conflicting.
Read →Epitalon: Sorting the Longevity Claims From the Evidence
A telomere-and-lifespan peptide resting almost entirely on small studies from a single Russian research lineage. Why that matters.
Read →Semax: Nootropic Peptide or Overstated Hype?
Marketed for focus and neuroprotection, Semax has a real research history — mostly outside Western journals and unproven in healthy people.
Read →Selank and Anxiety: A Look at the Limited Human Data
A Russian-developed anxiolytic peptide with real clinical use there and very little independent replication anywhere else.
Read →Melanotan II: Why the Tanning Peptide Carries Real Risks
The injectable tan jab is unapproved, broadly active, and linked to mole changes and melanoma in published case reports.
Read →PT-141 (Bremelanotide): The Evidence on Libido and Arousal
An FDA-approved drug for low desire in premenopausal women, and a popular off-label experiment. What the trials actually show.
Read →Thymosin Beta-4 and Tissue Repair: Reading the Preclinical Data
The molecule behind TB-500 shows real promise in animals. Translating that to humans is the unfinished, still-untested work.
Read →Tesamorelin: The One Peptide With Real FDA Approval
Approved in 2010 for HIV-associated lipodystrophy, tesamorelin is the rare research peptide with genuine phase 3 backing.
Read →Thymosin Alpha-1: What We Know About the Immune Peptide
Approved in 35+ countries as thymalfasin, with a real clinical record in hepatitis and sepsis. Not FDA-approved, and the evidence is mixed.
Read →TB-500: What the Research Does and Doesn't Show
Thymosin beta-4's fragment is sold for recovery. The preclinical signal is real; human evidence for athletic recovery is absent — and it's banned in sport.
Read →Ipamorelin: A Closer Look at the Growth-Hormone Secretagogue
A selective GH secretagogue with clean preclinical pharmacology, but no long-term human outcome data. What that gap really means.
Read →CJC-1295 and Ipamorelin: How the Combo Is Supposed to Work
Why these two growth-hormone secretagogues get stacked, and what the evidence does and does not support about the combination.
