Key Takeaways
- MK-677 (ibutamoren) is widely available online — no prescription needed from most vendors
- Expect to pay $30–80 for a 30-day supply at 25mg/day from a quality source
- Always require a third-party Certificate of Analysis (COA) before buying
- Capsules are the most convenient form; liquid works if you need custom dosing
- Red flag: any 30-day supply priced under $15 is almost certainly underdosed or fake
MK-677 — also known as ibutamoren — has become one of the most sought-after compounds for people looking to increase growth hormone levels, improve sleep quality, build muscle, and accelerate recovery. If you've done the research and you're ready to buy, the next question is: where do you actually get it, and how do you know what you're getting is real?
This guide covers exactly that — where to buy MK-677, what it costs, what form makes sense for you, and the red flags that should send you running from a vendor. Let's get into it.
Where Can You Buy MK-677?
There are three main routes to buying MK-677, each with its own tradeoffs:
1. Online Vendors (Most Accessible)
The majority of people buy MK-677 online through specialty supplement or peptide vendors. This is the most common route because it's accessible, doesn't require a prescription in most cases, and gives you the most variety in terms of form (capsules, liquid, powder) and dosing options.
The key is choosing a vendor that actually cares about quality. Not all do. We'll cover how to vet them below.
2. Compounding Pharmacies
Some compounding pharmacies carry MK-677 — but you'll typically need a prescription from a doctor to go this route. If you're working with an anti-aging clinic, hormone specialist, or functional medicine doctor, this can be a legitimate path. The upside: pharmaceutical-grade compounding under licensed oversight. The downside: significantly higher cost and the extra step of getting a prescription.
3. TRT Clinics and Wellness Clinics
An increasing number of TRT (testosterone replacement therapy) clinics and longevity/wellness practices include MK-677 in their protocols. If you're already working with a clinic for hormone optimization, it's worth asking whether they offer it. You'll pay a premium — but you get medical supervision and guaranteed quality.
What Forms Does MK-677 Come In?
Before you buy, it helps to know what format you're looking for. MK-677 is available in three main forms:
- Capsules / Tablets — Most popular. Pre-measured dose, easy to take, no measuring required.
- Liquid Solution — Typically 25mg/mL. Measured with a dropper. More flexible dosing but requires care to measure accurately.
- Powder — Raw powder is the cheapest per gram but requires a precision scale (0.001g accuracy) to dose properly.
MK-677 Cost: What to Expect
Pricing for MK-677 varies widely depending on the vendor, the form, and the dose. Here's a realistic breakdown of what to expect:
Typical Price Ranges
- 30-day supply at 25mg/day: $30–$80 from a reputable online vendor
- Per-mg cost: $1–$3/mg is a reasonable range — anything significantly under $1/mg should raise questions
- Monthly cost at 15mg/day: Roughly $20–$40
- Monthly cost at 25mg/day: Roughly $35–$70
Cost Comparison by Source
| Source | Estimated Monthly Cost | Convenience | Quality Assurance |
|---|---|---|---|
| Online Vendor | $30–$80 | High — ships to your door | Varies — COA required to verify |
| Compounding Pharmacy | $80–$200+ | Medium — requires prescription | High — licensed and regulated |
| TRT / Wellness Clinic | $150–$400+ | Low — appointments required | Highest — medical supervision |

What to Look for When Buying MK-677
Not all MK-677 is created equal. Here's what separates a trustworthy vendor from one you should avoid:
Certificate of Analysis (COA) — Non-Negotiable
A COA is a lab report that confirms what's actually in the product. Every legitimate vendor should make COAs available — ideally linked directly on their product page. If you have to ask for one and they can't produce it, move on.
What to look for on a COA:
- Purity: 99%+ is the standard for pharmaceutical-grade MK-677
- Independent lab: The testing should be done by a third-party lab — not in-house. Look for lab names like Janoshik, Colmaric, or similar independent testing facilities
- Batch number: The COA should match the batch of the product you're buying
- Identity confirmation: The report should confirm the compound is actually MK-677 (ibutamoren), not just any white powder
Clear Product Labeling
A trustworthy product will clearly state:
- Milligrams per capsule (or per mL for liquids)
- Total quantity
- Batch number
- Expiry date
- Ingredients list
Vague labeling is a red flag. If the bottle just says "MK-677" with no mg amount listed, skip it.
US-Based Shipping
Domestic US vendors ship faster and carry less customs risk than overseas suppliers. If a vendor is shipping from China or Eastern Europe with no US warehouse, you're rolling the dice on delivery times and potential customs holds.
Vendor Reputation
Check for reviews — both on the vendor's own site and on independent forums (Reddit's r/Peptides is a good starting point). Established vendors with a history of positive customer feedback are significantly lower risk than new sites with no track record.

MK-677 Forms: Capsules vs Liquid vs Powder
Choosing the right form comes down to convenience, precision, and cost. Here's a breakdown:
Capsules (Most Recommended)
Capsules are by far the most popular form — and for good reason. Each capsule is pre-measured, there's no mess, and dosing is completely straightforward. If you're taking 25mg/day, you just take one capsule. That's it.
Best for: Most users, especially beginners. Anyone who values simplicity.
Liquid Solution
Liquid MK-677 typically comes in 25mg/mL concentration and is measured with a dropper or oral syringe. It's a bit more work than capsules, but liquid form allows you to dial in an exact dose — which is useful if you're running a protocol that calls for something like 12.5mg or 20mg (half-doses or non-standard amounts).
Best for: Users who need precise, non-standard dosing. Those who find capsules hard to swallow.
Powder
Raw powder is the most cost-effective option per milligram, but it comes with the most friction. You need a precision scale capable of measuring 0.001g accuracy — anything less precise and you're guessing at your dose. Powder is better suited for experienced users who know what they're doing.
Best for: Experienced users comfortable with precise measuring. Those buying in bulk.

Red Flags to Avoid
The MK-677 market has its share of bad actors. Here's what should make you walk away immediately:
- No COA, or in-house testing only: If a vendor can't produce a third-party lab report, you have no way to verify the product is what they say it is
- Suspiciously low prices: Under $20 for a 25mg x30 supply is a red flag. Real MK-677 at proper purity costs more to produce
- No contact information or physical location: Legitimate businesses are contactable. Fly-by-night operations aren't
- No reviews or obviously fake reviews: Five-star reviews with no detail, posted within days of each other = almost certainly manufactured
- Overseas shipping with no US presence: Long delivery times and customs risk aren't worth it when domestic options exist
- Vague or missing labeling: Any product that doesn't clearly state the dose per unit is a skip
