Side-by-side observational reports from PeptIQ users. This compares self-reported patterns — not clinical head-to-head trials.
Last reviewed . By the PeptIQ team.
From check-in ratings — separate from side effects logged below. Side effects are logged separately from overall experience. A favorable check-in can still include nausea, fatigue, or injection-site reactions.
Favorable 51% · Mixed 32% · Unfavorable overall 17%
Benefits users selected when logging a favorable or mixed check-in.
Side effects are logged separately from overall experience. A favorable check-in can still include nausea, fatigue, or injection-site reactions.
Median bucket: 0.4–0.6 mg · Most common: 0.2–0.4 mg
Reports span 0.05–2 mg
Anonymized self-reports from PeptIQ users — not prescribing guidance. Buckets group similar logged amounts; open-ended top buckets mean “at least” that dose.
Among repeat reporters, 61% said they felt similar to their last entry, 43% more positive, and 21% more negative.
Overall, repeat reporters leaned more positive than their previous entry.
Median gap between entries: 23 days · Based on 514 repeat reporters
