Why This Matters
If you’re tracking macros, intermittent fasting, or simply watching intake, it helps to know what “counts.” Most signaling peptides are dosed in milligrams (mg), while protein and collagen are measured in grams (g). That difference is everything. 1
The Quick Math
- Protein and peptides = ~4 kcal per gram.
- Milligrams are tiny: 250 mg = 0.25 g → about 1 calorie.
- Typical capsule servings (often 50–500 mg total actives) land at ~0–2 calories.
That’s why most wellness peptides are considered calorically negligible in real-world tracking. 2
Peptides vs. Collagen & Protein Powders
| Product Type | Typical Dose | Calories? | Notes |
|---|---|---|---|
| Bioactive/signaling peptides (capsules, patches) | mg (milligrams) | ~0–2 kcal | Functional signals, not macronutrient intake. 3 |
| Collagen peptides / protein powders | g (grams) | 30–120+ kcal | Real protein = real calories; log as protein. 4 |
| Topical peptides (cosmeceuticals) | N/A (not ingested) | 0 kcal | No impact on macros or fasting. 5 |
Do Peptides Break a Fast?
Strictly: any calories could “break” a fast. Practically: low-milligram peptide servings contribute near-zero calories and generally don’t create meaningful digestive or insulin responses for most people. If you’re doing a strict protocol, take them outside your fasting window; otherwise, they’re unlikely to move the needle. 6
Where Amino Innovations Fits
We formulate non-injectable, human-identical (endogenous) peptides—capsules, topicals, and patches—made in cGMP facilities and third-party tested. Our capsules are dosed in milligrams, so their caloric impact is effectively negligible in daily tracking. 7
Canonical Actives (and Formats)
- BPC (BPC-157, capsule): supports soft-tissue recovery, gut integrity, and balanced inflammation.
- KPV (Lys-Pro-Val, capsule): supports immune and inflammation balance.
- CHILL (Pinealon + DHH-B, capsule): supports calm and restorative sleep.
- AGELESS (Epitalon + NMN, capsule): supports circadian rhythm and mitochondrial vitality.
- SKIN (topical): GHK-Cu, Acetyl Hexapeptide-8, Pentapeptide-18 for visible firmness and smoothness (0 kcal—topical use).
- HAIR (topical): GHK-Cu, Zinc Thymulin, PTD-DBM for scalp and follicle vitality (0 kcal—topical use).
- BLUE (Methylene Blue): non-peptide nootropic offered for complementary cognitive support; capsule doses are also mg-scale (negligible kcal).
Label Tips (So You Don’t Overcount)
- Check units: mg = negligible calories; g = log as protein/calories.
- Separate categories: signaling peptides ≠ collagen powders.
- Fasting? Take peptides outside strict windows if you want to be purist; otherwise, most mg-doses won’t meaningfully affect results.
Bottom Line
Yes, peptides technically have calories—but at mg-level doses they’re effectively calorie-negligible. Count collagen or protein powders; don’t sweat capsule-based signaling peptides.
