Frequently Asked Questions

Clear, research-based answers to the most common questions about peptides, research use, safety, storage, and ordering.

General Questions

What is ProfPeptide.com?

ProfPeptide.com is an educational resource dedicated to helping researchers understand modern peptides—including mechanisms, dosing data from clinical trials, safety profiles, and regulatory status. We also provide verified coupon codes for reputable peptide research labs.

Are the peptides on this site for human use?

Peptide products referenced on ProfPeptide.com are for laboratory research only, not for human consumption, medical use, or personal self-administration. Refer to vendor websites for additional information.

All information is educational.

Where do your peptide coupon codes work?

We partner with multiple well-known research peptide suppliers. Each code listed on our site is tested regularly to ensure it is valid. Codes typically work for retatrutide, semaglutide, tirzepatide, AOD-9604, BPC-157, and other research peptides.

Peptide Science & Mechanisms

What are peptides?

Peptides are short chains of amino acids that act as signaling molecules in the body. Many modern weight-management and metabolic therapies—like GLP-1, GIP, and triple-agonist compounds—are peptides.

How do GLP-1, GIP, and GLP-1/GIP/GCG peptides work?

  • Semaglutide → GLP-1 receptor agonist; slows gastric emptying & reduces appetite.

  • Tirzepatide → Dual GLP-1 + GIP agonist; enhances insulin sensitivity & metabolic rate.

  • Retatrutide → Triple agonist (GLP-1 + GIP + glucagon); increases fat oxidation and total energy expenditure.

Are peptides safe?

Published clinical trials show low rates of severe adverse events for GLP-1, dual, and triple agonists. However, these data refer to clinical-grade pharmaceuticals, not research products. Research peptides are not FDA-approved and should only be used under proper laboratory conditions.

Dosing & Research Use

How are peptides typically stored?

Most peptides require:

  • Refrigeration at 2–8°C

  • Protection from light

  • Avoiding repeated freeze/thaw cycles

  • Follow the supplier’s stability data sheet for specifics.

How long do reconstituted peptides stay stable?

Stability varies (7–30+ days depending on peptide and buffer). Always refer to the vendor’s COA or product specification sheet.

What are common research dosing patterns?

This is for educational overview only.

Clinical research typically uses:

  • Semaglutide: weekly, step-up dosing

  • Tirzepatide: weekly, step-up dosing

  • Retatrutide: weekly, with multiple dose levels explored in trials

    Research labs may explore micro-dosing or multi-dose protocols, but such use is experimental only.

Buying & Using Coupon Codes

How do I use a peptide coupon code from your site?

Each listing includes:

  1. Supplier link

  2. Code

  3. Discount amount

  4. Notes (e.g., exclusions, shipping rules)

Most codes are applied at checkout.

Do you guarantee the lowest price?

We test codes frequently, but pricing is ultimately set by each supplier. We do negotiate exclusive codes when possible.

Can I trust the peptide suppliers listed here?

We only feature suppliers that:

  • Provide Certificates of Analysis (COAs)

  • Have verified purity testing

  • Have a strong reputation in the research community

Shipping, Handling & Legal

Do peptide vendors ship internationally?

Many ship to the U.S., Canada, and EU. Some countries restrict peptide imports. Check local regulations.

Are research peptides legal?

In most jurisdictions, peptides designated as “Research Use Only — Not for Human Use” are legal to purchase for laboratory research. They are not legal for clinical, medical, or personal use.

Does ProfPeptide.com sell peptides directly?

No. We are an educational site and coupon-code hub. We do not manufacture, store, or sell any peptide products.

Website & Account

Do I need an account to use coupon codes?

No account is required. Discounts are publicly listed.

Will you send out updates or new coupon codes?

Yes, we periodically update codes and can provide new educational articles on emerging peptides like GLP-1s, GDF15 agonists, amlexanox, MOTS-C, and others.
