Peptide studies, from longevity clinics to formal early-phase trials, hinge on what was given, from which lot, when, and what happened next. Capture holds dose and injection records beside labs, adverse events and participant diaries, with an audit trail on every field.

ISRWhat a peptide study needs from its data system
The research context
Peptides are short chains of amino acids and range from long-established medicines to research compounds that have little human data. Studies run in very different settings: pharmaceutical development, academic trials, and a growing number of longevity and wellness clinics that want to document outcomes of the protocols they offer. These settings have one thing in common. The credibility of the dataset depends on knowing exactly what each participant received.
The regulatory position is changeable. In the United States, reports in 2026 described FDA moving to take a group of peptide bulk substances off its compounding "Category 2" list and seeking advisory committee input, while secondary sources conflict on where each substance now sits. Other jurisdictions have their own rules. This page does not tell you whether any product may be used; it tells you that you must establish the product's status with the regulator and your ethics committee before you enrol anyone. For the bigger picture see FDA expedited IND pilot program guide and EDC for early stage clinical trials.
The data model follows from this. Build an exposure form with product, lot or batch, preparation notes if relevant, dose, route, site and administrator, one row per administration. Where the protocol has a dose-reconstitution step, record it as its own documented field rather than a note. Lot numbers matter because an adverse event cluster that traces to one lot is a different finding from a spread across lots. For kit and inventory logic see IMP inventory and drug accountability software.
The visit schedule
Map the whole protocol into a schedule of assessments: baseline labs and body composition, scheduled administrations, safety labs and follow-up. Participants log home administrations on their phone, and staff see adherence by participant.

Protocol to build
| Need | What the data looks like | Where it lives in Capture |
|---|---|---|
| Exposure | Lot, dose, route, site, administrator, date | Administration eCRF, one row per dose; audit trail on each field |
| Safety | Injection-site reactions, systemic events | Adverse event form, SAE report form |
| Labs | Metabolic and safety panels with ranges | Lab results form |
| Other medicines | Supplements and drugs taken in parallel | Concomitant medications form |
| Home logs | Self-administration, symptoms, sleep | ePRO diary; sleep diary template |
| Wearable context | Sleep and recovery from the participant's own account | Optional native Oura connection, enabled per study |
Capture does not prepare, dispense or verify products. Compounding, supply and storage records stay with the pharmacy or manufacturer.
Build the administration form and diary in the free sandbox, run practice participants through a dosing cycle and open the export. No credit card.
Wearables and outcomes
Longevity-style peptide protocols often track sleep and recovery. The study team can enable the native Oura connection per study and mark it required; each participant connects their own account from a study page, and data syncs automatically with a visible last-sync time and a disconnect option. No other wearable is claimed. Use it as context for analysis, not as proof of mechanism. See Oura Ring clinical trial integration, EDC for longevity clinical trials and the wearable data sharing consent template.
Outcome design deserves more care than the product. Pick a small number of pre-specified endpoints, record their timing and avoid collecting dozens of loosely related measures that invite false positives. If you are a clinic documenting outcomes rather than running a formal trial, longevity clinics outcomes tracking software describes that mode, and you should still ask whether your activity counts as research and needs ethics review.
Capture provides 21 CFR Part 11-aligned controls (field-level audit trail, e-signatures, role-based access). That does not make a study compliant on its own; validated use is shared with the sponsor. This is not medical or legal advice.
Before first participant
Regulator and ethics committee agree how the product is classified and supplied for this study.
Lot, dose, route, site, administrator and date, one row per administration.
Each record shows who administered it.
Injection-site and systemic events defined; escalation path written.
If placebo-controlled, who sees allocation is decided and roles set.
eConsent text states the product status honestly.
Yes. Build an administration form with typed fields for lot, dose, route, site and administrator, one row per dose, with an audit trail on every field.
Capture cannot tell you. Product status in compounding and as an investigational product is changing in several jurisdictions. Check with the regulator and your ethics committee.
Yes. A diary opens from a phone link with reminders; no app install is needed.
The study team can enable the native Oura connection per study and participants connect their own account. No other device is claimed.
No. It does not prepare, dispense or verify products. Kit and accountability logging is described on the IMP inventory page.
