Your Biology is Programmable
Discover the science of peptides. Get personalized protocols, learn how to vet a practitioner, and follow the research without the hype.
What We Publish
Two pages we keep as dated, sourced records rather than as prose — every figure carries the source it came from and the date it applies to.
Price-per-mg index
Published US GLP-1 prices — manufacturer list, wholesale acquisition cost, self-pay and telehealth programs — normalized to dollars per milligram, so a $1,000 month and a $1,300 month can be compared on the only basis that means anything. Where a manufacturer publishes no price, the row says so and shows no number.
Regulatory status tracker
Where each peptide actually stands with the FDA — 503A and 503B compounding, approval status, and what changed when — kept per substance with a dated changelog instead of an explainer that goes stale the week after it publishes.
Frequently Asked Questions
Everything you need to know about peptides, protocols, and finding practitioners in NYC.
What are peptides and how do they work?
Peptides are short chains of amino acids that act as signaling molecules in your body. They bind to specific receptors to trigger biological responses like tissue repair, fat metabolism, muscle growth, and hormone regulation. Unlike medications that force a response, peptides work with your body's natural processes.
Are peptides legal in New York?
Research peptides are legal to purchase in New York for research purposes. However, peptides intended for human use require a prescription from a licensed healthcare provider. Peptides.NYC does not prescribe or make referrals — we publish guides on finding a licensed provider and the questions to ask, so you can decide with a qualified clinician whether peptide therapy suits your goals.
How do I find a peptide doctor in NYC?
Peptides.NYC does not operate a practitioner directory. We publish guides for finding and vetting one yourself: what peptide-specific training and sourcing practices to look for, the questions to ask at a first appointment, and what the clinic landscape looks like in Manhattan and Brooklyn. Always confirm a provider's license against New York State medical board records before you book.
What are the most popular peptides for beginners?
BPC-157 and TB-500 are commonly recommended for beginners due to their well-documented safety profiles and healing properties. For weight management, semaglutide and tirzepatide are popular options that require medical supervision. Our Peptide Navigator quiz helps match you with protocols suited to your specific goals.
How should I store my peptides?
Reconstituted peptides should be stored in a refrigerator at 36-46°F (2-8°C) and used within 4-6 weeks. Lyophilized (powder) peptides can be stored at room temperature but last longer refrigerated. Never freeze reconstituted peptides. Keep all peptides away from direct light and heat.
