PEPTIDE TIMING PRINCIPLES: (1) GH AXIS PEPTIDES — GH secretion is pulsatile and gated by somatostatin. To maximize GH pulse amplitude: inject in a fasted state (insulin and blood glucose suppress GH release), and time doses to coincide with natural GH pulse windows. Primary windows: early morning (pre-breakfast), post-workout (if fasted or low-carb pre-workout), and pre-sleep (the largest natural GH pulse occurs in the first 90 minutes of deep sleep). For CJC-1295 no DAC + Ipamorelin: inject 2-3x daily — AM fasted, pre-workout (optional), and pre-bed. For CJC-1295 with DAC: 1-2x per week (long half-life provides sustained GH elevation). For MK-677: once daily, pre-bed (causes hunger and drowsiness in some users). (2) GLP-1 AGONISTS — Long half-lives (semaglutide ~7 days, tirzepatide ~5 days) allow once-weekly dosing at any time. Consistency matters more than specific timing. Some users prefer evening injection to sleep through initial nausea. (3) HEALING/RECOVERY PEPTIDES — BPC-157 and TB-500 can be dosed 1-2x daily without timing restrictions. Some practitioners recommend injecting BPC-157 as close to the injury site as possible (local injection) for targeted healing — though systemic SubQ also works. (4) SLEEP PEPTIDES — DSIP and melatonin-promoting peptides (Endoluten, Pinealon): 30-60 minutes before desired sleep time. (5) NOOTROPIC PEPTIDES — Morning dosing preferred for cognitive benefits (Semax, Selank, Adamax, Noopept). Effects last 4-8 hours. Evening dosing may interfere with sleep. (6) BIOREGULATORS — Course-based protocols typically call for morning administration.

Injection Timing — When to Take What
💡 Tips
THE 30-MINUTE RULE: For GH peptides, avoid eating for 30 minutes before and after injection. Insulin spikes from food blunt GH release. This is the single most impactful timing factor. STACKING TIMING: If injecting multiple peptides, they can generally be drawn into the same syringe and injected together (e.g., CJC-1295 no DAC + Ipamorelin in one shot). However, some peptides should NOT be mixed in the same syringe — check compatibility. When in doubt, inject separately at different sites.
