The UK's deepest library of research peptide stacks
Mechanism of action for every peptide. Summarised studies on every combination. Full research protocols — dosing, timing, cycle length, safety profile and UK regulatory notes. Strictly for in vitro and laboratory research.
In partnership with PeptideAuthority.co.uk — full monographs for every peptide referenced on this site.
Stacks by research goal
Filter by mechanism class — healing & tissue repair, longevity, nootropic, metabolic, recovery and the growth-hormone axis.
Most-studied research stacks
Combinations with the strongest in vitro and animal-model evidence base. Each page contains the full protocol, dosing table, weekly timeline and safety profile.
BPC-157 + TB-500 + GHK-Cu Advanced Recovery Protocol
Three-peptide advanced soft tissue + dermal remodelling research stack. Adds GHK-Cu copper peptide to the canonical BPC-157/TB-500 base for collagen-I:III ratio improvement.
BPC-157 + TB-500 Healing Stack — Full Research Protocol
The most-studied tissue-repair peptide combination — BPC-157 with TB-500. Mechanisms, summarised studies, full dosing table, weekly timeline and UK regulatory note.
CJC-1295 + Ipamorelin + Tesamorelin Growth Hormone Stack
Synergistic GHRH + GHRP + GHRH-analog research stack for the somatotropic axis. Mechanism, dosing, timing and UK regulatory notes.
Epitalon + Humanin + MOTS-c Longevity Stack — Research Protocol
Three-peptide longevity research stack targeting telomerase activation, mitochondrial unfolded-protein response and metabolic ageing. Full dosing protocol and UK regulatory note.
KPV + LL-37 Gut Healing Research Stack
KPV α-MSH tripeptide and the human cathelicidin LL-37 — an immunomodulatory + antimicrobial peptide stack studied for intestinal mucosal research.
Semax + Selank + Pinealon Nootropic Stack
Russian-origin neuropeptide nootropic research stack — BDNF up-regulation, anxiolytic action and pineal cognition support. Full intranasal research protocol.
Mechanism, not marketing
Every peptide in every stack is described by its receptor target and signalling pathway — not by consumer benefit claims. Citations link back to the underlying preclinical research.
Full research protocols
Each stack page includes a complete dosing table, weekly timeline matrix, cycle length, and post-cycle observations from published in vitro and animal studies.
UK regulatory clarity
Plain-English summary of MHRA position on each compound. No clinical claims; we only describe what the peer-reviewed literature has reported in research subjects.
Latest research summaries
Synthesised reviews of recent peptide combination literature.
