Results Timelines
0 to 30 minutes post-injection:
- Peptide enters systemic circulation and begins receptor binding
- Mild injection site warmth or redness may occur
- Nausea, if it occurs, typically begins within this window
30 to 60 minutes:
- Peak plasma concentration reached
- Initial onset of effects reported by many users
- Flushing and warmth may become apparent
1 to 4 hours:
- Maximal therapeutic window
- Effects on desire, arousal, and genital sensitivity are most pronounced
- Blood pressure elevation peaks between 2 to 4 hours post-dose
4 to 8 hours:
- Therapeutic effects gradually diminish
- Despite a plasma half-life of approximately 2.7 hours (range 1.9 to 4.0 hours), biological effects on sexual function persist for 6 to 8 hours in clinical observations, likely reflecting receptor residence time and downstream neurochemical changes
8 to 12 hours:
- Blood pressure and heart rate return to baseline
- Systemic clearance is essentially complete within 8 to 10 hours
- 64.8% is excreted in urine and 22.8% in feces
Individual response varies. Some users report effects within 15 to 20 minutes, while others require up to 90 minutes for onset. The prescribing information advises patients to determine their own optimal timing through experience.
