Peptide AI, powered by Regrowth Intelligence
Ask about any peptide. Get it prescribed.
Honest answers in seconds. Licensed clinicians and pharmacies handle the rest.
The AI educates. It doesn't diagnose or dose. A licensed clinician makes every treatment decision.
What do you want to feel different?
Choose a goal. The AI shows which peptides clinicians consider for it and which you can start now.
Peptides you can start this week.
Prescribed by licensed clinicians, filled by licensed pharmacies, shipped to your door.
Prices are starting monthly medication prices and vary by dose. Prescriptions are issued only if a clinician decides a therapy is right for you. Waitlist peptides were cleared from FDA's restricted list in April 2026 and recommended by its compounding advisory committee in July 2026; licensed pharmacies can fill them once FDA finishes its rulemaking, and waitlist members hear first.

Bloodwork, before and during.
Labs show whether a peptide is safe for you to start and whether it's working once you do. Here's what clinicians commonly check. Your clinician decides what you actually need and when.
Sermorelin
Growth hormone axis
IGF-1, fasting glucose and A1c, thyroid (TSH, free T4), CMP
IGF-1 at about 6 to 12 weeks to guide dosing, then every 6 months; glucose or A1c with it
Raising growth hormone raises IGF-1 and can nudge blood sugar up.
Tesamorelin
Growth hormone axis
IGF-1, fasting glucose and A1c, lipids, CMP
IGF-1 and glucose periodically, as the FDA label advises; A1c every 3 to 6 months
The label warns about raised blood sugar and recommends monitoring IGF-1.
GLP-1 therapy
Semaglutide, tirzepatide
A1c, fasting glucose, CMP (kidney and liver), lipid panel; history check for pancreatitis and thyroid cancer
A1c and CMP about every 3 months at first, then every 6 months; kidney function if you get vomiting or dehydration
Doses are adjusted to glucose response, and dehydration from GI side effects can strain the kidneys.
PT-141
Bremelanotide
Blood pressure check rather than blood work; review heart history
Blood pressure if you have risk factors
It can briefly raise blood pressure, so uncontrolled hypertension rules it out.
GHK-Cu (topical)
Hair, scalp and skin
No routine labs for topical use. For shedding, see the hair panel below
None routinely
Applied to the skin, very little reaches the bloodstream.
NAD+
Energy support
CMP (kidney and liver) is common practice
Usually none unless symptoms appear
There's no established monitoring standard; clinicians check organ function as a baseline.
Hair program
Shedding and thinning
Ferritin, CBC, TSH, vitamin D; DHT, testosterone or androgen panel when relevant
Ferritin and vitamin D at 3 to 6 months if they started low
Low iron, thyroid problems and low vitamin D are common, fixable causes of shedding.
Waitlist peptides
BPC-157, TB-500, KPV, MOTS-c, epitalon, semax
No established protocol yet. Expect a baseline CBC and CMP once they can be prescribed
To be set by your clinician
Human safety data is limited, so baseline organ function matters.
This is general information, not a lab order. Timing varies with your dose, history and results. Draws are done at a local lab, and your clinician reviews every result with you.
A peptide program built by hair-loss people.
Regrowth Peptides comes from the team behind Regrowth.com, the first hair-loss network on the web. Our hair and scalp program pairs copper-peptide scalp care with the treatments that already have the strongest evidence.
- Topical GHK-Cu for scalp and skin, prescribed when appropriate
- Built to work alongside minoxidil and finasteride, not replace them
- Labs that matter for shedding: ferritin, thyroid and vitamin D (see the labs guide)
- Referrals to vetted hair-restoration surgeons when a transplant makes more sense
"For thirty years I've watched people buy hair-loss products they couldn't verify. Peptides are the same story today. This is the version I'd want: real clinicians, real pharmacies, straight answers."
Scott Hoffman founded Regrowth.com, whose community grew to more than 50,000 members including physicians, dermatologists and trichologists, and has formulated hair-loss treatments for decades.

From your first question to your door.
Ask the AI
Get clear answers on any peptide, including what's legal to prescribe today.
Take the assessment
Answer one concern at a time. It takes about three minutes and builds a summary for your clinician.
Meet your clinician
A provider licensed in your state reviews your summary, orders labs if needed, and decides on a plan with you.
Delivered and monitored
Your licensed pharmacy ships your prescription, and your clinician checks in to adjust as you go.
Your assessment, one question at a time.
Say yes to what's bothering you and we'll ask a couple of quick follow-ups. Your answers become a summary a clinician can act on.
Simple pricing. No surprises.
Asking the AI and taking the assessment cost nothing. You pay for the consult, and for medication only if it's prescribed.
The legit way to get peptides.
"Research use only" vials online aren't made or tested like medicine. Here's what you get instead.
A clinician decides
No automated prescribing. A provider licensed in your state reviews every case.
Licensed pharmacies
Prescriptions come from state-licensed pharmacies with tested, documented batches.
Only what's legal now
We prescribe what can lawfully be prescribed today. Pending peptides stay on the waitlist.
Medication screening
Your history and current medications are checked for interactions before your consult.
Lab-informed
Bloodwork is ordered when it changes the decision, then used to track progress.
Matched to your state
You're routed to a clinician licensed where you live, following your state's rules.
Ongoing check-ins
Your clinician follows up on results and side effects and adjusts or stops therapy as needed.
Straight about evidence
When most research is in animals, the AI and your clinician will say so.
Questions people ask first.
Can I get BPC-157 prescribed?
Not yet. FDA's advisory committee recommended it in July 2026, but pharmacies can't legally compound it until FDA completes rulemaking. Join the waitlist and we'll email you the day prescribing opens.
How fast can I start?
Most people finish the assessment in about three minutes. A clinician reviews it within one business day, and approved prescriptions usually ship within a few days of your consult.
Does the AI prescribe or tell me what dose to take?
No. It explains peptides and the evidence behind them. Your clinician sets any dose after reviewing your history and, when needed, your labs.
Are compounded peptides FDA-approved?
No. Compounded medications are made by licensed pharmacies for individual patients, but they aren't FDA-approved products. Some items, like tesamorelin and bremelanotide, also exist as FDA-approved brands.
Which states do you serve?
It depends on clinician licensing in your state. Your assessment confirms availability before you pay for anything.
Is my information private?
Your assessment is shared only with the clinicians and pharmacy involved in your care. See our Privacy policy for details.
