Peptides are short-chain amino acid sequences — the body's own molecular messengers. The right peptide, dosed correctly, tells specific cells exactly what to do: repair, regenerate, optimize, protect.
The Science
Peptides are chains of 2–50 amino acids — smaller than proteins, larger than individual amino acids. This precise size is what gives them their power: they're small enough to be absorbed efficiently, yet complex enough to carry specific biological instructions to targeted cell receptors.
Unlike conventional supplements that provide building blocks and hope for the best, therapeutic peptides act as cellular signals — triggering specific repair cascades, upregulating or downregulating gene expression, and modulating immune response with remarkable precision.
The peptides in our catalog are bioidentical sequences — identical in structure to those produced by your own body — formulated as oral capsules and sprays for practical, accessible use.
Acid-resistant coating protects the peptide through the stomach, releasing it in the small intestine for systemic absorption. Best for full-body and lower-GI targets (e.g., BPC-157 DR for gut healing, leaky gut).
Dissolves in the stomach, releasing the peptide for upper-GI absorption. Ideal when targeting esophageal, gastric, or upper digestive issues — and for rapid systemic uptake in some formulations.
Sublingual absorption delivers peptide directly into the bloodstream through oral mucosa — bypasses GI digestion entirely. Fastest onset; ideal for peptides requiring intact systemic delivery (e.g., KPV Spray).
Mixable powder formulas allow flexible dosing and combine multiple active compounds. Often used for gut-lining and microbiome support (Gut Feeling) where consistent daily delivery is the priority.

Neuropeptides that cross the blood-brain barrier to support neurotransmitter balance, neural repair, sleep cycle regulation, and cognitive performance. Used by practitioners for brain fog, memory, mood, and neurological support.
CerebroPep™
Comprehensive neuropeptide blend for cognitive function, focus, memory, and neurological repair. The flagship brain optimization formula from Integrative Peptides.
CogniPep
Targeted cognitive support formula — used for processing speed, working memory, and sustained mental clarity throughout the day.
PinealPep
Pineal gland support peptide targeting melatonin regulation, circadian rhythm, and deep sleep architecture. Popular for sleep disorders and anti-aging protocols.
The most clinically documented peptide category. BPC-157 and KPV are used extensively in functional and integrative medicine for gut lining repair, leaky gut, IBS, SIBO, and systemic inflammation driven by GI dysfunction.
BPC-157 PURE Delayed Release
Body Protection Compound — one of the most extensively studied peptides for gut healing, tissue repair, and inflammation modulation. Delayed-release coating for small intestine delivery.
KPV Ultra Oral Spray
Tripeptide (Lys-Pro-Val) with potent anti-inflammatory action. Sublingual spray delivers KPV directly into systemic circulation — used for gut inflammation, IBD support, and immune modulation.
BPC-157 Immediate Release
Standard (non-enteric-coated) BPC-157 capsule — releases in the stomach. Used for upper GI targeting, esophageal healing, and protocols requiring faster systemic uptake.
Gut Feeling
Comprehensive gut microbiome and lining support powder — a daily foundation formula combining prebiotics, postbiotics, and gut-specific nutrients. Available in three flavors.
Gut Feeling Support
Capsule version of the gut support blend — all the benefits of the Gut Feeling formula in convenient capsule form for clients who prefer not to mix powder daily.
Peptide fragments and metabolic modulators that support fat mobilization, lean mass preservation, and satiety signaling. Used by practitioners for weight loss resistance, body recomposition, and metabolic optimization.
Frag Max
Enhanced Frag formula — higher-potency body composition peptide for accelerated fat mobilization and lean mass support. For those progressing from the standard Frag formula.
Frag
Growth hormone fragment peptide (176–191) — specifically isolated for its fat-mobilizing activity without the insulin-disrupting effects of full-length GH. The standard starting formula.
Frag Oral Spray
Sublingual delivery of the Frag peptide sequence — for clients who prefer spray over capsule, or who want faster onset through sublingual absorption.
Can't Weight
Satiety and metabolic support blend — designed to address weight loss resistance through appetite regulation, metabolic rate support, and leptin sensitivity optimization.
Peptides targeting thyroid signaling, hypothalamic-pituitary function, and hormonal axis optimization. Used by practitioners supporting subclinical hypothyroidism, Hashimoto's, and general hormonal balance.
ThyroPep
Thyroid-specific peptide formula supporting thyroid receptor signaling, T4→T3 conversion, and overall thyroid gland health. Used alongside conventional thyroid protocols or as a standalone support supplement.

Epitalon Pinealon
Dual formula combining Epitalon (telomere-protective tetrapeptide) and Pinealon (pineal gland neuropeptide). A flagship longevity protocol used in anti-aging medicine for decades in Eastern European research.
Thymogen Alpha-1
Thymus-derived peptide that modulates T-cell function and immune surveillance. Used for immune deficiency, chronic infection susceptibility, autoimmune conditions, and post-illness immune rebuilding.
Why Peptides
Peptides bind specific receptors with precision — triggering exact biological responses rather than general nutrition
Bioidentical sequences that mirror what your body already produces — recognized and utilized immediately
Many peptides upregulate or downregulate specific genes — creating lasting changes beyond the dosing period
Targeted signaling produces measurable changes in weeks rather than months of standard supplementation
Bioidentical peptides are broken down into amino acids after use — the body processes them as food
Oral peptide formulations are available without a physician's prescription — unlike injectable peptide therapies
Clinical Outcomes
Across gut healing, cognitive performance, body composition, and immune resilience.
I've been prescribing BPC-157 in injectable form for years. Having an oral option that patients can take at home without a prescription has completely changed how I manage gut healing cases.
After 3 weeks on CerebroPep, the brain fog I'd lived with for two years started lifting. By week six I was sharper than I'd been since my 30s. Nothing else I tried came close.
I plateaued at 20 lbs from my goal weight for 8 months. Added Frag and Can't Weight to my protocol. The plateau broke in three weeks. Down 18 more lbs over the next four months.
