Peptides, explained
without the noise.
What each compound actually is, how it was dosed in the research, and what the data shows. No recommendations — just organised information.
BPC-157: What the Evidence Actually Shows
What BPC-157 is, why the published research is almost entirely preclinical, its FDA and WADA status, and what the July 2026 advisory vote did not change.
Injection Site Rotation and Lipohypertrophy
What lipohypertrophy is, why injection guidance insists on rotating sites, and what the FITTER recommendations say about spacing, needle reuse and inspection.
GeneralPeptide Half-Life: Why Schedules Differ
Why some peptides are injected daily and others weekly — DPP-4 degradation, albumin binding, and what half-life means for steady state and a missed dose.
GeneralReconstitution and Concentration: The Arithmetic
What reconstitution does to a lyophilised peptide, why concentration is the only number that matters, and how mg, ml and syringe units relate to each other.
SemaglutideSemaglutide: What It Is and How It Works
What semaglutide is, how it acts on the GLP-1 receptor, and what the STEP and SELECT trials found about body weight and cardiovascular outcomes.
GeneralPeptide Storage: What Actually Degrades Them
Why peptides are fragile molecules, what breaks them down — heat, light, freeze-thaw cycles and agitation — and what the official labelling says.
TirzepatideTirzepatide: What It Is and How It Works
What tirzepatide is, how it activates the GIP and GLP-1 receptors at the same time, and what the SURPASS and SURMOUNT trials actually found.
