The FDA’s current framework for research peptides in 2026 — the Category 1/2/3 compounding classification system, which peptides were reclassified and why, SAFE Act implications, and what ‘for research purposes only’ actually means under federal law.
Most research peptides are synthesized in China. Does that matter? A candid look at where peptides come from, what manufacturing standards actually mean, and why third-party testing is the only thing that counts.
Hormonal changes after 40 shift the biological landscape for women. Here is what preclinical and clinical research says about peptides studied in the context of those changes.
Mixing peptides in a single syringe is convenient — but not always safe or stable. This guide covers compatibility, common combinations, and when to use separate injections.
A research overview of five peptides investigated in nerve damage and neuropathy models: BPC-157 (peripheral crush injury, VEGF), Semax (BDNF/NGF upregulation, ischemic neuroprotection), Cerebrolysin (multi-factor neurotrophic mimicry, clinical RCT data), PE-22-28 (TREK-1 blockade, hippocampal neurogenesis), and GHK-Cu (nerve growth gene expression from Connectivity Map analysis).
A comprehensive FAQ for researchers studying tirzepatide: covering the dual GIP/GLP-1 mechanism, SURMOUNT trial data, dosing escalation schedule, reconstitution protocol, side effect profile, and comparisons to semaglutide and retatrutide.
For most research peptides, women can use the same compounds as men. GLP-1s, BPC-157, and TB-500 are not sex-specific. Here is where the differences actually lie — GH secretagogues, PT-141, and pregnancy guidance.
BPC-157, TB-500, GHK-Cu, and Thymosin Alpha-1 have all been studied in the context of post-surgical tissue repair, wound healing, and immune recovery. A review of what the preclinical and clinical literature shows.
Most research peptides bypass hepatic first-pass metabolism entirely. Here is what the science says about peptides and liver health, hepatoprotective findings, and which peptides warrant monitoring.
Janoshik is the peptide industry’s most-cited third-party lab. But their HPLC tests have real limitations. Learn what a Janoshik report actually confirms — and what it doesn’t cover.
