- 1
Tell your doctor, even if you're doing it on your own
In simple words: Your doctor can't protect you from what they don't know about.
- Share everything you take or plan to take: what, how often and since when.
- It changes how your labs are read and helps catch interactions with your other medicines.
- If your doctor disagrees, keep the conversation going; they may spot a risk you can't see.

Get baseline bloodwork first
In simple words: Know your numbers before you change anything, so you can tell if something helps or harms.
- Use the doctor letter on the bloodwork page for a full baseline panel.
- Add the peptide / GH / GLP-1 safety panel (IGF-1, glucose, insulin, A1C, CBC, PSA if relevant).
- Retest about every 3 months, and stop to recheck if anything feels off.
- 3
Know what you're actually buying
In simple words: “Research use only” products aren't checked by anyone for what's really inside.
- Prescription GLP-1s filled by a licensed pharmacy are the safest source. FDA has warned about counterfeit and unapproved versions sold online.
- Gray-market peptides can be mislabeled, under- or over-dosed, contaminated, or carry bacterial toxins (endotoxin).
- A seller's certificate of analysis (COA) doesn't prove what's in your vial. Independent third-party testing lowers the risk but doesn't remove it.

Change one thing at a time
In simple words: If you start three things at once and feel bad, you won't know which one caused it.
- Add one new product at a time and give it a few weeks before changing anything else.
- Keep a simple log: what, when, and how you feel (sleep, energy, appetite, side effects).
- Don't start anything new while you're sick, pregnant or about to have surgery.
- 5
Clean injection habits
In simple words: Most injection problems are infections, and they're preventable.
- Use a new sterile needle and syringe every time, and never share them.
- Wash your hands, clean the vial top and the skin with an alcohol swab, and rotate injection sites.
- Don't use anything cloudy, discolored or with particles. Store products exactly as labeled.
- Put used needles in a proper sharps container.
- 6
Know who should avoid them
In simple words: Some people should not use these at all without specialist advice.
- Pregnant, breastfeeding or trying to conceive.
- Personal or family history of medullary thyroid cancer or MEN 2 (GLP-1 medicines).
- History of pancreatitis, or a personal or strong family history of cancer: speak to a specialist first.
- Under 18, or managing a serious heart, kidney or liver condition.
Stop and get medical help if you notice
- Spreading redness, heat, swelling, pus or fever around an injection site
- Hives, swelling of the face or throat, or trouble breathing: call 911
- Severe belly pain that won't go away, sometimes spreading to the back
- Chest pain, a racing or irregular heartbeat, or fainting
- Sudden loss or blurring of vision
- Vomiting so much you can't keep fluids down
Why there are no doses here
For unapproved peptides, safe and effective human doses simply haven't been established, and every product varies. Approved GLP-1 medicines follow a prescriber-led step-up; if side effects hit after an increase, read a slower step-up.
