Questions

Frequently asked

Do you sell peptides?+
No. Subcutera is an education and community platform only. We link to third-party products and suppliers, clearly labeled, but never sell peptides ourselves.
Are peptides legal or FDA-approved?+
Most research peptides are not FDA-approved, and their legal status is actively changing. Each profile lists the current status. Always consult a licensed provider.
Is this medical advice?+
No. Everything here is general education for adults, not individualized medical advice. We always point you to a licensed healthcare provider for personal decisions.
How do you make money?+
Through clearly labeled advertising, affiliate links, and sponsored supplier placements. We disclose every commercial relationship.

Harm Reduction

Injection Safety

If a person chooses to inject, doing it cleanly dramatically lowers the risk of infection and harm. This page exists for safety, modeled on public-health harm-reduction resources.

ImportantNot encouragement or instruction to start. Harm-reduction information only, not medical advice. Talk to a licensed provider before using any injectable.

Clean technique, step by step

Wash and sanitize

Wash hands thoroughly with soap, then clean and clear your work surface.

Inspect and prep

Check the vial and solution for clarity, then swab the stopper with an alcohol wipe.

Swab the site

Clean the injection site with a fresh alcohol wipe and let it fully air-dry.

Rotate sites

Never inject the same spot twice in a row. Rotating reduces irritation and scar tissue.

Dispose safely

Never reuse needles. Drop them straight into a proper sharps container.

Interactive · Site rotation

Tap a spot, or rotate through them

Subcutaneous injections are usually given in the fatty tissue of the abdomen, the back of the upper arms, or the thighs. Rotating between spots gives each site time to recover. Tap any marker on the body, or press Rotate to move to the next site.

Next site Recently used Available

Illustration for general education only. Not medical advice or instruction to inject. Confirm technique and sites with a licensed provider.

When to seek medical care

WarningStop and get help if you notice spreading redness, swelling, warmth, pus, fever, or trouble breathing. When in doubt, contact a medical professional or emergency services.

Emergency and poison-control resources (US)

Life-threatening emergency, severe allergic reaction, or trouble breathing: call 911. Suspected poisoning, overdose, or a bad reaction: call Poison Control at 1-800-222-1222 (free, confidential, 24/7). Outside the US, contact your local emergency number. If you are in crisis, in the US you can call or text 988.
