Peptide therapies
Small molecules. Specific jobs.
Peptides are short chains of amino acids — the same building blocks your body already uses to tell one cell what to do next. These nine are the ones a New Tides physician may prescribe. Each one is a prescription medicine, and each one has to be the right answer for you before it is written.
The six
Each is prescribed on its own, by the route listed. How a peptide is taken is part of what makes it the right preparation — so where you see one route, that is the only route we offer.
Subcutaneous injection · Intramuscular injection · Topical · Oral
BPC-157
When the same spot keeps flaring.
How it works →For a gut that acts up, or an old injury that still nags long after it should have settled down.
It is a copy of a protein found in your own stomach lining. Most of the research has looked at how it affects the gut wall and how connective tissue knits back together.
What people say: The thing people mention most is a nagging joint or a touchy stomach bothering them less than it did. Some people notice nothing at all.
Subcutaneous injection · Intramuscular injection
TB-500
For stiffness that outstays its welcome.
How it works →For stiffness and soreness that hangs around too long after you train, or after an injury.
It is a fragment of a protein your body already makes, called thymosin beta-4, which is involved in how tissue rebuilds itself.
What people say: Usually described as moving more freely and being ready to train again sooner. It is the one people most often pair with BPC-157.
Subcutaneous injection · Intramuscular injection
MOTS-c
When the tiredness isn't about sleep.
How it works →For being tired in a way that more sleep does not seem to fix.
It is made inside your mitochondria, the parts of your cells that turn food into energy. Almost every other peptide is coded by the cell nucleus; this one is not.
What people say: People tend to describe steadier energy across the day rather than a lift and a crash. Gym-goers mention getting through sessions they used to fade in.
Subcutaneous injection · Intramuscular injection
Epitalon
For the 3am wake-up that won't stop.
How it works →For broken sleep — especially the 3am wake-up you cannot get back down from.
It comes from the pineal gland, the part of your brain that runs your body clock. Research on it has focused on sleep timing.
What people say: Falling asleep more easily and staying asleep is what comes up most. It is taken in short courses rather than every day, which people often find unusual at first.
Intranasal
Semax
For the fog that shows up at 2pm.
How it works →For brain fog, and the drop-off in focus that shows up in the afternoon.
It was developed in Russia and has been studied for attention and mental stamina. You take it as a nose spray, which is how it reaches the brain.
What people say: People describe staying with one task longer instead of bouncing between tabs. It is not a stimulant, and the usual report is no jitteriness and no crash afterwards.
Topical · Oral
KPV
When your gut and your skin flare together.
How it works →For flare-ups you can see or feel — a temperamental gut, irritated skin, or both at the same time.
It is the business end of a signalling molecule your body already makes: just three amino acids long. It has been studied in gut and skin conditions.
What people say: People most often mention flare-ups coming less often, or passing more quickly when they do.
Used alongside each other
BPC-157 + TB-500
Two of the most-studied repair peptides, often used together. They are prescribed as two separate preparations on one protocol rather than mixed into a single vial — same two peptides, kept as two.
Three more worth knowing
Subcutaneous injection
Sermorelin
For the recovery that used to be automatic.
How it works →For sleep and recovery that used to happen on their own and now do not.
It tells your pituitary gland to release your own growth hormone, instead of giving you hormone from outside. Your body stays in charge of how much and when.
What people say: Sleep is almost always the first thing people bring up, usually before anything else. Recovery between workouts comes up next.
Subcutaneous injection · Intramuscular injection
Glutathione
For dullness that sleep doesn't fix.
For skin that looks dull and tired, and for generally feeling run down.
It is the main antioxidant your liver makes, and your body uses it constantly. Levels fall with age, illness and stress.
What people say: Brighter-looking skin is what gets mentioned most, along with feeling less run down. It is also the one people ask about for hangovers.
Subcutaneous injection · Intramuscular injection
NAD+
For running on empty by noon.
How it works →For running out of steam by lunchtime, and the foggy thinking that comes with it.
It is a coenzyme every single cell uses to turn food into energy and to repair DNA. The amount you have drops as you get older.
What people say: Energy and mental clarity are the two things that come up again and again. People who have had it by IV often say the injection is easier to keep up with.
What changed in 2026
- All six spent two and a half years on an FDA list of substances with safety concerns. In April 2026 they came off it.
- The FDA’s own advisory committee reviewed each one and voted in its favour.
- Health and Human Services has since said it will not pursue licensed US pharmacies that compound them, provided strict conditions are met.
- Those conditions are the part that matters to you: one active ingredient per preparation, made by an FDA-registered manufacturer, and tested lot by lot for identity, purity, potency, endotoxins and heavy metals.
This is not FDA approval, and the policy can be withdrawn. Compounded medications are not FDA-approved and are not reviewed by the FDA for safety, effectiveness or quality. What it does mean is that anything prescribed here is written by a licensed physician, prepared by a licensed US pharmacy, and made from material with documented testing behind the batch.
These are things people commonly report about these compounds — not results from New Tides patients, and not what you should expect. Individual responses vary, many people notice nothing, and nothing here is a promise that any of it will happen for you.
Compounded medications are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or quality.
Whether any of this is right for you is a medical decision, made by a licensed physician after reading your history. Some histories rule these out completely, and asking about something is never the same as being prescribed it. Pricing is confirmed with you before anything is dispensed — nothing is charged until your physician has written the prescription.
