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 97% · Mixed 3% · Unfavorable overall 0%
Benefits users selected when logging a favorable or mixed check-in.
Median bucket: 2+ mg · Most common: 2+ mg
Reports span 1 to ≥ 2 mg (open-ended top bucket)
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, 90% said they felt similar to their last entry, 10% more positive, and 0% more negative.
Overall, repeat reporters leaned more positive than their previous entry.
Median gap between entries: 163 days · Based on 20 repeat reporters
