Why isn't my peptide working?
When a peptide seems not to work, the usual suspects are wrong timeline, wrong goal, dose math error, poor tracking, storage problem, bad vial, or expectations borrowed from hype content.
First checks
- Are you still inside the normal timeline?
- Is the peptide actually matched to your goal?
- Did you mix mg and mcg?
- Was the vial stored correctly?
- Are you tracking the outcome clearly?
- Did the vial look normal after mixing?
Timeline mismatch
Some effects are expected quickly. Others are not. Quitting at week 2 because a week-8 effect has not happened is not a compound failure.
Data beats vibes
Track dose, date, sleep, weight, symptoms, performance, pain, or whatever outcome matters. Without a baseline, it is hard to know if anything changed.
