ARA-290 / Cibinetide

An erythropoietin-derived tissue-protective peptide studied in small phase 2 neuropathy trials. Schedules are disease-specific and remain investigational.

Community-reported schedule

Community-reported · not a validated schedule

Community dose schedule

Community-provenance subcutaneous dosing from an authenticated research forum, about 1.3-4 mg once daily (commonly 2 mg) in roughly 30-day courses. Forum reports only, not a validated or trial-verified schedule.

Dosage and protocol evidence

Each card states what the quantities are based on. A third-party or animal schedule is not a validated human dose.

Human StudySubcutaneousOnce daily for 28 days
Adults with type 2 diabetes and painful neuropathy

4 mg subcutaneously once daily for 28 days

This phase 2 schedule was followed by another 28 days of observation and is not a routine-use protocol.

Reports include 1 mg daily for 30 days, 2.5 mg before exercise and 4 mg daily in multi-compound inflammation or pain stacks

These anecdotes are mixed and confounded. The 4 mg amount resembles a study quantity but does not reproduce the studied population, 28-day design or monitoring; raw/peptide-education/pe-tb-500-frag.md:247-249 and raw/discussions/disc-ask-med-expert.md:8935-8938.

authenticated research-forum (Peppys) reports and expert commentary

Subcutaneous reports cluster around 1.3-4 mg once daily (most settling near 2 mg, a few titrating to 6 mg) in roughly 30-day courses with about 60-day breaks; because the peptide tends to gel or cloud, members add plenty of bacteriostatic water plus sodium bicarbonate, or a few drops of injectable acetic acid, and aim for pH around 4-5

Forum provenance from an authenticated archive with usernames omitted. Reported quantities are consistent for neuropathic and anti-inflammatory use but are not a controlled schedule; the subcutaneous route is preferred, with intranasal noted only as a possible alternative, and quantities are not interconverted between routes.

Evidence summary

An erythropoietin-derived tissue-protective peptide studied in small phase 2 neuropathy trials. Schedules are disease-specific and remain investigational.

Protocol basis

The page reports the repeated 28-day subcutaneous research design used in small neuropathy studies, with the population and monitoring context attached.

Community provenance (Peppys)

An authenticated research-forum archive records subcutaneous ARA-290 clustering around 1.3-4 mg once daily, most reports settling near 2 mg and a few titrating as high as 6 mg, run in roughly 30-day courses with about 60-day breaks. The recurring technical theme is reconstitution: the peptide tends to gel or cloud, so members add plenty of bacteriostatic water plus sodium bicarbonate, or a few drops of injectable acetic acid, aiming for a pH near 4-5. Reports are consistent and positive for neuropathic and anti-inflammatory use, with benefit fading after discontinuation; the subcutaneous route is preferred and intranasal is mentioned only as a possible alternative, without interconverting quantities. Usernames are omitted and the planner above reproduces the arithmetic of the reported quantities rather than validating them.

What remains uncertain

Larger confirmatory trials, long-term safety, approved indications and equivalence to commercial research vials remain unresolved.

Warnings and contraindications

ARA-290 remains investigational and is not a general neuropathy treatment.
The cited daily schedule was tested for 28 days in small monitored studies.
Results from specific neuropathy populations do not establish broader use.
Organised research bench with labelled storage tray, vial rack, notebook and thermometer
A clean workspace supports traceability. It does not establish sterility.

Supplies and general handling

Keep the universal checklist short. Product-specific labelling and source documentation always take priority over a general guide.

Research vial

Bacteriostatic water

Use only a diluent appropriate to the research method and formulation.

Storage follows the label

Do not apply a universal refrigerator rule. Follow the product, diluent and study documentation for temperature, light and expiry.

Use sterile equipment once

CDC injection-safety guidance calls for a new sterile needle and syringe for each injection and entry into a medication container.

Stability is formulation-specific

Do not infer a post-mixing lifetime from BAC water alone. Discard material when identity, integrity or sterility is in doubt.
