Icotrokinra
Approved for plaque psoriasis in the US and EU in 2026.
A peptide taken as a once-daily tablet. It blocks the receptor, the pathway that some injected psoriasis biologics target. An made by Johnson & Johnson (with Protagonist), also called Icotyde and JNJ-2113.
What the evidence shows
Side effects and risks
Who should avoid it: Ask the prescriber about infections and vaccines, as with other drugs that act on IL-23.
How it works
- Where it acts
- It blocks IL-23 receptors on immune cells.
- What it changes
- It turns down the immune signalling that drives psoriasis plaques.
- What people notice
- Clearer skin over weeks to months in trials, with side effects close to placebo.
How it is taken
One 200 mg tablet a day on waking, with water, at least 30 minutes before food. For adults, and children from age 12 who weigh at least 40 kg.
Getting it in the United States
The legal route for Icotrokinra
Get a prescription from a licensed clinician. Fill it at a licensed pharmacy or through the maker's own direct service.
Prescription from a dermatologist
FDA approved in 2026-03 for moderate to severe plaque psoriasis in adults and in adolescents 12 and over weighing at least 40 kg who qualify for systemic therapy or phototherapy. Sources checked give no price or coverage details.

Routes people use for any peptide in the United States
Telehealth prescribing
Online clinics prescribe after a questionnaire, sometimes with no live doctor visit, and mail the drug. FDA moved in February 2026 to restrict mass-marketed compounded copies and claims that they are generic equivalents.
Risk: Thin medical screening. Compounded versions are not reviewed by FDA for quality.
Covers: Approved GLP-1 drugs, compounded semaglutide and tirzepatide
Source: GZERO Media, Apr 2026
Clinical trial enrolment
The only lawful way to get an unapproved peptide drug with medical monitoring. ClinicalTrials.gov lists eligibility, sites and phone numbers. Researchers note recruitment is hard when people can buy the drug on the gray market instead of risking placebo.
Risk: Possible placebo assignment, strict eligibility and travel to a study site.

Routes people use for any peptide in the United States
Compounding pharmacy with prescription
A clinician prescribes and a pharmacy compounds. Twelve peptides left the FDA do-not-compound category in April 2026 and a panel backed six in July, but they are not yet formally eligible. Pharmaceutical-grade ingredient is scarce.
Risk: Legal status is unsettled until FDA rulemaking ends. Pharmacies may use research-grade ingredient.
Covers: BPC-157, TB-500, KPV, MOTS-c, Semax, Epitalon and similar

Med spas and weight-loss clinics
Very common. Secret shoppers called 75 clinics and med spas in two states after shortages ended. 92 percent offered compounded semaglutide and 87 percent tirzepatide, often mixed with B vitamins to look custom.
Risk: Four of 23 suppliers lacked sterile compounding licenses and four had disciplinary records.

Concierge and longevity doctors
Cash-pay physicians build peptide plans for wealthy clients. Reporting from San Francisco says some source from overseas channels, domestic research-use-only sellers or the few compounding pharmacies that will supply clinicians.
Risk: A doctor's involvement does not guarantee a pharmaceutical-grade product.

Cross-border purchase or import
FDA says importing drugs for personal use is illegal in most cases but it may not object to small personal quantities in limited situations. Reporting also describes people travelling to Mexico for injections.
Risk: Packages can be seized. Product origin and cold-chain handling are hard to check.
Covers: Approved prescription peptides sold abroad

Routes people use for any peptide in the United States
Research-chemical websites
Sites sell vials marked for research or not for human consumption, with no prescription. FDA says some ship direct to consumers with dosing directions, and it has sent warning letters. Retatrutide exists only through this route or trials.
Risk: Unknown identity, strength and sterility. No pharmacist or prescriber involved.
Covers: Retatrutide, semaglutide, tirzepatide, BPC-157 and most unapproved peptides
Source: FDA, unapproved GLP-1 drugs page
Direct orders from Chinese factories
Buyers message factory sales agents and pay by crypto or payment app. A minimum order of about ten vials pushes people to buy in bulk and share. A blockchain analysis found US buyers were the largest source of funds.
Risk: Many of the same vendors list fentanyl precursors. Lab reports sent by sellers cannot be verified.
Covers: GLP-1 copies, melanotan II, BPC-157, TB-500, GHK-Cu, epitalon

Chat groups and social sellers
Dealers are found through Telegram, WhatsApp, Discord and influencer discount codes. In a May 2026 survey of 1,000 US users, 14.5 percent bought this way and three quarters asked an AI chatbot for dosing.
Risk: 45 percent of social media buyers in that survey reported an emergency or urgent care visit for a reaction.

Legal last-resort routes
Expanded access (compassionate use)
For a serious or life-threatening condition with no comparable alternative and no trial you can join. Your physician asks the company for the drug, then files with FDA and an ethics board. The company can refuse. Costs are often not insured.
Right to Try
For a life-threatening condition after approved options are exhausted and no trial is open to you. The drug must have finished Phase 1 and be in active development. Your doctor asks the manufacturer directly. FDA does not review requests.
Source: FDA, Right to Try
Trial finders
Search ClinicalTrials.gov by condition or drug name, check eligibility and call the listed site. ResearchMatch is a free NIH-funded registry that lets researchers find you. Discuss risks with your own clinician before enrolling.

Personal import for serious conditions
FDA may not object when a US citizen imports up to about three months of a drug for a serious condition with no effective US treatment, with written personal-use confirmation and a US doctor's details. It is discretion, not a right.
Source: FDA, personal importation
Patient-specific compounding
When the approved product cannot meet a specific need of an identified patient, a prescriber can order a compounded version from a licensed pharmacy. Lower price alone does not qualify. Ingredients must be pharmaceutical grade.
Questions people ask
What is icotrokinra approved for?
Moderate-to-severe plaque psoriasis, sold as Icotyde. FDA approved it in March 2026 and the EU authorized it in September 2026, for adults and children from age 12 who weigh at least 40 kg.
How well does icotrokinra work for psoriasis?
In the two head-to-head ICONIC-ADVANCE trials, about 70% of people reached clear or almost clear skin at 16 weeks.
Is icotrokinra a pill or an injection?
A pill. It is a peptide taken as one tablet a day on waking, with water, at least 30 minutes before food.
What are the side effects of icotrokinra?
Side-effect rates in the trials were within about one percentage point of placebo. It is new, so rare or long-term effects will show only with wider use; ask the prescriber about infections and vaccines.
Does icotrokinra work for ulcerative colitis?
In a phase 2b trial, about 64% responded against 27% on placebo. Phase 3 trials are running in ulcerative colitis, psoriatic arthritis and Crohn's disease.
