The peptides people ask about — explained honestly

What each is studied for, what people commonly experience, what to watch for, and the nutrition that supports your goal. No protocols here — your provider sets your plan. This is the context to walk in informed.

Available through supervised care Pending FDA / PCAC review — early-access waitlist only
How to read these pages. Peptides are a category, not a single thing, and the evidence behind them ranges from well-studied to early and preliminary. We describe what each compound is studied for or commonly discussed for — not what it's proven to do for you. Whether any peptide is appropriate, and at what dose, is a decision only a licensed provider can make based on your health history and labs.

BPC-157

"Body Protection Compound" · injectable / oral forms discussed
Pending review

A synthetic peptide derived from a protein found in gastric juice. It's most discussed in the recovery and gut-health space and is among the peptides under FDA/PCAC review in 2026, so it's offered through early access only, not for purchase.

What it's studied for

  • Soft-tissue and tendon recovery support
  • Gut and digestive comfort
  • General recovery and resilience

Much of the evidence is preclinical (animal) or early; human data is limited. Treat the upside as promising, not proven.

What people commonly report

  • Faster perceived recovery from nagging strains
  • Calmer digestion for some users
  • Effects that build gradually over weeks, not overnight

⚠ What to watch for

Injection-site irritation, mild nausea, lightheadedness, or headache are the most commonly mentioned. Tell your provider about any unusual swelling, persistent pain, or reactions. Because product quality varies wildly in the gray market, sourcing only through your supervised plan is itself a safety measure.

Nutrition that supports the goal

If your goal is tissue recovery, the foundation is adequate protein (spread across the day), vitamin C and zinc for collagen synthesis, and an anti-inflammatory pattern — plenty of vegetables, omega-3 sources like salmon, and limited alcohol, which blunts healing. Hydration and sleep do more heavy lifting here than most people expect.

TB-500

Thymosin beta-4 fragment · injectable
Pending review

A synthetic version of a fragment of thymosin beta-4, often paired conceptually with BPC-157 in recovery discussions because they're thought to act on different repair pathways. Also under review and early-access only.

What it's studied for

  • Tissue repair and flexibility/mobility support
  • Recovery from overuse-type strain

Human clinical evidence is limited; most data is preclinical.

What people commonly report

  • Gradual improvements in mobility and recovery
  • A slower onset than they expect — patience required

⚠ What to watch for

Fatigue or a "head rush" feeling shortly after dosing is sometimes reported, along with injection-site reactions. Report anything that feels off — especially chest symptoms, severe headache, or significant fatigue — to your care team.

Nutrition that supports the goal

Same recovery foundation as above: protein adequacy, anti-inflammatory whole foods, and the micronutrients tissue repair depends on (vitamin C, zinc, magnesium). Consistent meals beat sporadic "perfect" ones.

CJC-1295 / Ipamorelin

Growth-hormone secretagogues · injectable
Pending review

Often discussed together as a pairing. Rather than supplying growth hormone directly, these are studied for prompting the body's own pulsatile GH release. Commonly framed around recovery, body composition, and sleep quality.

What it's studied for

  • Supporting the body's natural GH rhythm
  • Recovery, lean-mass support, sleep quality

What people commonly report

  • Deeper sleep, often the first noticeable change
  • A flush, warmth, or tingling shortly after dosing
  • Improved recovery over weeks

⚠ What to watch for

Water retention, tingling or numbness in the hands, head-rush or flushing, increased appetite, and injection-site reactions are the most common mentions. Because these influence GH/IGF-1, supervision and periodic labs matter — flag any persistent swelling, numbness, or vision changes promptly.

Nutrition that supports the goal

Adequate protein is central if the goal is body composition. Many providers advise being mindful of food timing around dosing, since a heavy meal close to administration can blunt the GH pulse — but follow your provider's specific guidance rather than internet rules of thumb. Prioritize sleep nutrition (e.g., avoiding alcohol and very late large meals), since sleep is where much of the benefit is realized.

Sermorelin

GHRH analog · injectable
Available via supervised care

A growth-hormone-releasing hormone analog with a longer track record in clinical use than many newer peptides. Like the pairing above, it's studied for prompting the body's own GH release rather than replacing it.

What it's studied for

  • Supporting natural GH production
  • Recovery, sleep, and vitality in adults with low output

What people commonly report

  • Improved sleep depth
  • Gradual recovery and energy changes over 1–3 months

⚠ What to watch for

Injection-site redness or itching, flushing, headache, or dizziness are the most common. Report persistent or worsening symptoms. Periodic lab monitoring is standard.

Nutrition that supports the goal

Protein adequacy and good sleep nutrition support the outcomes people seek. As with other GH-axis peptides, your provider may have specific timing guidance relative to meals.

GHK-Cu

Copper peptide · topical / injectable forms discussed
Pending review

A naturally occurring copper-binding peptide most established in skin and cosmetic science. Topical GHK-Cu is widely used in skincare; systemic forms are more exploratory and fall under the review umbrella.

What it's studied for

  • Skin appearance, firmness, and repair (topical)
  • Hair and tissue support (exploratory)

What people commonly report

  • Improved skin texture and tone with topical use
  • Subtle, cumulative changes rather than dramatic ones

⚠ What to watch for

Topically: skin irritation or sensitivity, especially when layered with strong actives like retinoids or vitamin C. Patch-test first. For any systemic form, copper balance is a real consideration — another reason supervision matters.

Nutrition that supports the goal

For skin and tissue: protein, vitamin C, zinc, and a colorful, antioxidant-rich diet. Avoid over-supplementing copper on your own, since balance with zinc matters.

NAD+

Coenzyme · injectable / IV / nasal / oral precursors
Available via supervised care

Not a peptide in the strict sense, but frequently grouped with this category in wellness settings. NAD+ is a coenzyme central to cellular energy metabolism; it's offered in several delivery forms and as oral precursors (like NR and NMN).

What it's studied for

  • Cellular energy and metabolic support
  • Recovery and general vitality (early evidence)

What people commonly report

  • Energy and mental-clarity changes (variable)
  • With IV/injectable: flushing, nausea, or chest tightness if infused too fast — slowing the rate usually resolves it

⚠ What to watch for

The infusion-rate sensitivity above is the main thing — which is exactly why supervised administration matters. Report any flushing, racing heart, or nausea so the rate can be adjusted.

Nutrition that supports the goal

Niacin-containing foods (poultry, fish, legumes, whole grains) and overall metabolic-supportive eating. Sleep, movement, and limiting alcohol support NAD+ status as much as any product.

Glutathione

Antioxidant tripeptide · injectable / IV / oral / nasal
Available via supervised care

The body's primary intracellular antioxidant. Used in wellness settings for antioxidant and detoxification support and sometimes for skin brightness, across several delivery forms.

What it's studied for

  • Antioxidant and oxidative-stress support
  • Skin tone/brightness (commonly marketed; evidence mixed)

What people commonly report

  • Subtle wellness or skin changes over time
  • Generally well tolerated

⚠ What to watch for

Injection-site reactions; rarely, cramping or allergic-type reactions. Report any breathing difficulty or rash immediately. Long-term skin-lightening use is not well established for safety.

Nutrition that supports the goal

Sulfur-rich and antioxidant foods support your own glutathione: cruciferous vegetables (broccoli, Brussels sprouts), garlic and onions, and protein providing cysteine. Whole-food antioxidants complement any supervised protocol.

Curious whether any of these fit you?

Start with an assessment, not a cart. A licensed provider reviews your history and labs and decides what — if anything — is appropriate.
