There’s been a wave of peptide capsules, pills, and gummies popping up everywhere. They’re being pushed as “easier” alternatives to injectables. No needles, just swallow and go.

Sounds great, right?
Here’s the problem: most oral peptides don’t work.

If you’re buying peptides in pill form—like BPC-157, TB-500, or CJC-1295—you’re probably getting scammed.

Why Oral Peptides Usually Don’t Work

Peptides are fragile chains of amino acids. When you take them orally, they have to survive your stomach acid, digestive enzymes, and then get absorbed through the gut lining—all before they ever reach your bloodstream.

And that almost never happens.

Low Bioavailability = Wasted Product

Most oral peptides have terrible bioavailability. Studies show that less than 1% of the active peptide actually makes it through the digestive system into circulation.

“Oral delivery of peptide drugs faces significant challenges due to enzymatic degradation and poor permeability across the gastrointestinal tract.”
— Pharmaceuticals, 2020 (MDPI)

More recent studies from 2024–2025 confirm the same issue. Even with advanced delivery tech (like enzyme inhibitors or nano-formulations), most peptides still break down before doing anything useful.

But I See Oral BPC, Semax, and CJC Being Sold…

Yeah, you do. Doesn’t mean they’re effective.
The truth is:

• BPC-157 may have some oral/gut benefits when taken in liquid form, but it’s still far less effective than injecting.
• Semax & Selank are usually sold as nasal sprays—not oral—and they actually do work via that route because they bypass digestion entirely.
• CJC-1295, Ipamorelin, TB-500, and most others? Completely broken down if swallowed.

So if someone’s selling you a pill version of these… red flag.
If it’s not injectable or a well-studied delivery method like nasal or sublingual spray, you’re throwing your money away.

Why Injectables Still Win

Injectables go directly into your system. No stomach acid. No enzymes breaking things down. What you inject is what your body absorbs.

Here’s what you get with injectables:

• Full bioavailability
• Faster and more consistent results
• Lower dosages needed
• Better control over timing and response

That’s why PlatPharma sticks to injectables for 99% of our peptide range. Because they actually work.

So Why Do Companies Push Oral Peptides?

Simple: it’s easy money.
They can sell cheap capsules that cost nothing to make and charge a premium for “convenience.” Most buyers don’t know any better, so they assume it’s legit.

They’re not selling results.
They’re selling marketing.

PlatPharma’s Approach

We don’t play games. We only stock oral peptides when there’s real evidence behind their absorption and effects—like our oral NAD+ powder, which is mixed with water and consumed for maximum effectiveness.

Everything else? Injectables. Always tested, always dosed correctly, and always done right.

You’re not here to waste time or money. You’re here for products that work.

Bottom Line

• Most oral peptides are a scam—especially if they’re in capsule or pill form.
• New tech is improving things slightly, but even in 2025, it’s limited to niche peptides with special delivery systems.
• Injectables are still the gold standard for effectiveness, safety, and consistent results.
