Peptides Prescribed By Actual Doctors So You Get The Most Out of Them
Every protocol is reviewed by a licensed physician and every vial ships with a batch certificate of analysis — so what you study is exactly what you ordered.
How it works
A doctor reviews your protocol before anything ships
No guesswork and no self-diagnosis from a forum thread. You complete an intake, a licensed physician reviews it against your history, and the material that arrives is matched to what you are actually trying to move.
STEP 01
Complete the assessment
A ten-minute intake covering history, current medication, labs and what you are trying to move. It is the input the whole protocol is built from.
STEP 02
A physician reviews it
A licensed provider reads the intake against your history, checks interactions and timing, and either confirms the protocol or proposes a different pathway.
STEP 03
Material ships with its paperwork
Your order leaves within 24 hours in cold-chain packaging, and the certificate of analysis for that exact lot is waiting in your account.

Purity & testing
Every lot tested. Every certificate published.
Purity is a claim until someone shows the chromatogram. Each batch is sent to an independent laboratory for HPLC purity and mass-spec identity, and the result is filed against the lot number you receive — downloadable from your account indefinitely.
If the lot does not pass, it does not ship. There is no house-tested tier.

Research programs
Start from the pathway, not the compound
A category groups material by chemistry. A program groups it by what is being studied — the comparison table, the titration schedule and the lab panels all live together.
WM
Weight Management
Peptides studied for body composition and appetite signalling — GLP-1, GIP, glucagon and amylin.
HH
Heart Health
Cardiovascular and lipid pathway research compounds — lipids, pressure and endothelial function.
Lab tests at home
Full panels without leaving your house
A collection kit arrives in the post, you take the sample at your kitchen table, and it goes back in the prepaid mailer. Results land in your account in a few days — and they become the baseline your protocol is built on.
1
Kit ships free and arrives in two to three days, with everything labelled.
2
Finger-prick or saliva sample at home — no clinic, no appointment, no fasting queue.
3
Prepaid mailer back to the lab; results in your account in three to five days.
Metabolic
Metabolic & Insulin Panel
Fasting glucose, insulin, HbA1c and HOMA-IR — the baseline for any GLP-1 protocol.

FAQ
Questions we get most
Purity and testing, storage and shipping, who can order, and how each pathway is actually studied.
How is purity established for each lot?
Every lot is tested by an independent laboratory using HPLC for purity and mass spectrometry for identity. The certificate of analysis is attached to the lot number in your account before the order ships, and it stays downloadable indefinitely.
How is the material shipped and stored?
Injectables and lyophilised vials dispatch within 24 hours in insulated cold-chain packaging. Store unopened vials at −20 °C; once reconstituted with bacteriostatic water, refrigerate at 2–8 °C and observe the stability window on the product page.
Who can order from the catalogue?
Ordering requires a registered account with a valid doctor referral code, and the account holder must certify that all material is handled for laboratory research use only. Nothing sold here is for human or veterinary use.
Which compound should a first protocol use?
Most researchers start with a single-agonist GLP-1 because the published dose-response data is deepest there, then move to a dual or triple agonist when the study design calls for a larger effect size. Mechanism, not potency, should drive the choice.
