Real questions.

The protocols

How do I know which protocol is right for me?

Take the 7-minute intake. Our medical director reviews your goals, history, and contraindications and recommends a protocol. We don't sell vials to people we don't think will benefit.

Can I stack peptides?

Yes, with physician oversight. Common stacks: Tirzepatide + Tesamorelin for aggressive body recomposition. BPC-157 + GHK-Cu for systemic recovery and skin. Your protocol design will recommend stacks if appropriate.

What's the difference between Retatrutide and Tirzepatide?

Tirzepatide is the proven, well-studied dual-agonist with FDA approval (as Mounjoro/Zepbound). Retatrutide is the next-generation triple-agonist with stronger Phase 2 weight-loss numbers but is still investigational. We recommend Tirzepatide for most patients; Retatrutide for those who've plateaued or who want the strongest available molecule.

What if it doesn't work for me?

Tirzepatide and Retatrutide have ~85% response rates in the published trials. If you're a non-responder, our physician adjusts the protocol or switches molecule. We're invested in your outcome, not just the sale.

Pricing & payment

How can your pricing be so much lower than US clinics?

Three reasons. (1) Colombian magistral compounding under Decreto 2200/2005 has lower regulatory overhead than US 503A pharmacies. (2) Operating cost in Medellín is roughly one-third of comparable US cities. (3) We don't pay the FDA-enforcement risk premium that US compounders pass to customers. The molecule is identical; the supply chain is different.

How do I pay?

Crypto (USDT or USDC — 5% discount), Wise Business international transfer, or Colombian COP bank transfer. Once payment is confirmed, we pack and ship within 24–48 hours.

Do you offer refunds?

If a vial arrives damaged, mislabeled, or fails QC, we refund or replace immediately. We don't refund for "didn't like the side effects" — peptides have known side-effect profiles and you'll review them with our physician before ordering.

Shipping & access

Where do you ship?

Within Colombia only. We serve patients who are physically in Colombia for the duration of their protocol, or medical-tourism patients who visit Medellín for intake and continue with refills shipped within-country.

I'm flying in from the US — can you have a protocol ready for me?

Yes. Complete the intake before you arrive. Our medical director reviews your case and prepares your protocol. We can arrange in-clinic dispensing, hotel delivery, or pickup at our El Poblado office. Many medical-tourism patients combine their visit with a stay in Medellín.

How does cold-chain shipping work?

Validated insulated packaging with ice packs. Temperature loggers available on request. Shipping via Servientrega, DHL, or our local moto courier in Medellín. Transit 24–72 hours depending on city. If transit will exceed cold-chain integrity, we delay shipping rather than risk product quality.

Quality & safety

How do you test the product?

Every batch goes to Janoshik Analytical in Prague before shipping. HPLC purity, mass-spec identity, water content, residual solvents. The COA is on every product page and the lot number is on every vial. You can verify the lot independently at janoshik.com.

Who is your medical director?

A Colombian-licensed physician with 12+ years in regenerative medicine, bilingual EN/ES. Full credentials available during intake. We deliberately don't put the physician's full bio on the public site for privacy reasons; you'll meet our medical director during your intake.

What if I have a serious side effect?

WhatsApp the medical team immediately — we have a 24-hour line for active patients. For severe symptoms (chest pain, severe abdominal pain, allergic reaction), call emergency services first, then notify us. We track and report serious adverse events per Colombian pharmacovigilance requirements.

The company

Who runs Medellin Peptides.co?

Every prescription is individually issued by our medical director under the magistral framework. We follow INVIMA pharmacovigilance reporting requirements.
