Peptide
library.
A straightforward reference library for peptides and related compounds: benefits, evidence, practical use, reference dosing and clear context.
Try terms like fat loss, weight loss, recovery, collagen, focus, gut or growth hormone.
Reference ranges shown here are curated educational references, not individualized recommendations. Regulatory status and evidence vary by compound and use.
GHK-Cu
Naturally occurring copper-binding tripeptide researched for collagen signalling, skin quality, extracellular-matrix remodelling and tissue repair.
Reference
1 mg/day (days 1–15), then 2 mg/day
Daily, before bed
GLOW
Vendor/community blend name for a co-formulation of GHK-Cu, BPC-157 and TB-500; evidence comes from the individual components rather than the three-peptide blend itself.
Reference
2.5 mg per injection
Daily wk 1–4, 5×/week wk 5–8, 2–3×/week wk 9–12 · 4 weeks off
KLOW
Four-peptide research blend combining GHK-Cu, BPC-157, TB-500 and KPV; the evidence base belongs to the individual components rather than the co-formulation.
Reference
1.6–4.8 mg per injection
Daily initially, then 5×/week, then 2–3×/week in the cited 12-week protocol · 12 weeks
BPC-157 / TB-500 (Wolverine)
Research blend name for BPC-157 + TB-500; one 2026 rat tendon study tested the combination directly, but no controlled human blend trial has established efficacy or dosing.
Reference
500 mcg
Daily, morning · 8 weeks on, 8 weeks off
BPC-157
Synthetic 15-amino-acid peptide with extensive animal research in tissue-repair and gastrointestinal models but very limited human evidence.
Reference
250–500 mcg daily
Daily · 4–6 weeks
TB-500
Synthetic thymosin-beta-4-related fragment researched for wound and tissue-repair biology, with no established human clinical evidence for the fragment itself.
Reference
1–2.5 mg
2–3× weekly · 4–6 weeks
