What Is Super Human Blend (SHB)? The Complete Research Guide

If you've encountered the name "Super Human Blend" — often abbreviated SHB or marketed as a "super human peptide blend" — and found mostly thin vendor pages, this guide is the reference those pages aren't. Below: exactly what's in it, what each component is studied for, what the published dosing literature says (and how the vial compares), and how SHB differs from the sequence-defined peptides it shares shelf space with.

Super Human Blend, defined

Super Human Blend is a composition-driven research formulation: nine free amino acids and amino-acid-derived compounds in one lyophilized vial, typically stated at 865 mg total. Unlike BPC-157, TB-500, or CJC-1295 — single molecules with a defined amino acid sequence — SHB has no peptide backbone. Each component is an independent molecule with its own research literature; the blend exists to study their interaction, not to deliver one targeted signal.

That distinction is the first thing a careful researcher (or a careful buyer evaluating vendors) should check: any page calling SHB a "peptide" without this clarification is glossing over the most important fact about the product.

What's inside: the nine components

(amounts per standard 865 mg vial — always verify against your supplier's batch documentation)

L-Citrulline (120 mg) — the most efficient precursor in the nitric oxide pathway. Citrulline is converted to arginine in the kidneys, and because it bypasses first-pass metabolism and gut uptake limits, it raises plasma arginine more reliably than oral arginine itself. Exercise-physiology research typically studies citrulline at 3–8 g/day — far above the per-component amount here, which is itself informative (see "What the dosing literature says").

L-Arginine (110 mg) — the direct substrate for nitric oxide synthase (NOS), the enzyme family that produces nitric oxide from arginine. Studied extensively for vascular function, endothelial health, and exercise performance. Its known weakness — limited oral bioavailability and short plasma half-life — is precisely why it is paired with citrulline in this blend.

L-Ornithine (110 mg) — a urea-cycle intermediate. When arginine is metabolized, one byproduct is ammonia; ornithine supports the cycle that clears it. Ornithine plus arginine combinations appear in research on fatigue during prolonged exercise and on pituitary growth-hormone release. In pathway terms, ornithine completes the loop that arginine and citrulline open.

L-Carnitine (220 mg) — the largest single component. Carnitine is the shuttle that transports long-chain fatty acids into mitochondria for oxidation; without it, fat-derived energy production stalls. Research programs study carnitine for exercise metabolism, fatigue biomarkers, and recovery markers. Typical published doses run 1–3 g/day.

N-Acetyl-L-Cysteine (75 mg) — a cysteine donor. Cysteine is the rate-limiting building block of glutathione, the cell's principal endogenous antioxidant, which makes NAC one of the most-studied redox compounds in the literature (typical study range 600–1,800 mg/day).

L-Lysine (70 mg) — an essential amino acid, meaning the body cannot synthesize it. Research areas include collagen cross-linking, calcium absorption, and its synergistic pairing with arginine in GH-secretagogue studies.

L-Proline (60 mg) — the signature amino acid of collagen, which is roughly one-third proline and hydroxyproline. Studied in connective-tissue, skin, and wound research; pairs naturally with lysine, which is required for collagen cross-linking.

L-Taurine (60 mg) — a sulfonated amino acid (technically not an amino acid at all, but conventionally grouped with them). Taurine regulates cellular hydration, calcium handling in muscle tissue, and membrane stability, and acts as an antioxidant. Exercise studies commonly use 1–3 g/day.

L-Glutamine (40 mg) — the most abundant free amino acid in plasma and muscle. A nitrogen donor studied in gut-barrier, immune-function, and muscle-protein research under training stress. Published studies typically use 5–10 g/day.

The three pathway groupings researchers care about

The nine components aren't random. They cluster into three convergent research areas:

1. Nitric oxide & vascular function (citrulline → arginine → ornithine)

This trio is the blend's centerpiece. Citrulline supplies arginine sustainably; arginine feeds NOS to produce nitric oxide (a vasodilator central to blood-flow, nutrient-delivery, and blood-pressure research); ornithine clears the ammonia generated by the cycle so it doesn't become rate-limiting. Studied individually, each has a bottleneck. Studied together, the question is whether the combined substrate availability changes the output of the whole pathway — that is the rationale for the blend format.

2. Cellular energy & fatigue (carnitine + taurine)

Carnitine governs whether fatty acids reach the mitochondria; taurine governs how cells handle the calcium and osmotic load of contraction. Both appear in exercise-metabolism and fatigue literature from different angles — substrate delivery and cellular environment.

3. Redox & structural matrix (NAC, glutamine, lysine, proline)

NAC feeds glutathione synthesis; glutamine is the nitrogen backbone of repair processes; lysine and proline are the collagen pair. In recovery and tissue research, these four cover antioxidant defense and structural substrate simultaneously.

What the dosing literature actually says (the honest section)

This is where most vendor pages go quiet, and where a serious researcher should pay attention. The per-vial component quantities in SHB — 40 to 220 mg each — are well below the doses used in published human trials of the individual amino acids:

Component

Typical published study dose

Amount in SHB vial

Citrulline

3–8 g

120 mg

Arginine

3–6 g

110 mg

Carnitine

1–3 g

220 mg

Taurine

1–3 g

60 mg

NAC

0.6–1.8 g

75 mg

Glutamine

5–10 g

40 mg

Two honest conclusions follow. First, SHB is not a clinical-dose replication of any of these studies — anyone claiming the vial "delivers" the studied doses of nine compounds at once is doing arithmetic that doesn't survive contact with the literature. Second, that's not necessarily the point: the blend format is a legitimate research tool for studying interactions at combined, sub-clinical concentrations — synergy, pathway crosstalk, and matrix effects that single-compound studies can't observe. Understanding which of those two things a given study (or a given vendor claim) is actually doing is the single most useful critical skill in this niche.

Typical research question

"How do pathways interact?"

"What does this signal do?"

Neither category is "better" — they answer different questions, and some research programs use both. If your question involves peptide signaling, see our BPC-157 + TB-500 blend and the peptides hub. If it involves substrate-level pathway interaction, SHB is the relevant article.

Handling, reconstitution & storage

SHB ships lyophilized (freeze-dried) for stability. Standard laboratory practice: refrigerate at 2–8 °C, protect from light, reconstitute with bacteriostatic water using aseptic technique, and treat the solution as a standard laboratory reagent. See our reconstitution guide and bacteriostatic water.

How to evaluate an SHB supplier

Regardless of where you buy, five checks separate credible suppliers from label artists:

1. Batch-specific third-party testing — a COA per batch (HPLC purity, identity, sterility), not a generic "99% pure" banner.

2. Stated composition with exact amounts — all nine components, per vial. Vague "proprietary blend" labels hide underdosing.

3. Consistent labeling — the vial, the product page, and the COA should state the same total content.

4. Realistic claims — vendors promising clinical-study results from a 865 mg amino acid vial either don't know the literature or assume you don't.

5. Clear research-use positioning — with appropriate handling documentation.

Frequently asked questions

What is the Super Human Blend peptide?
A nine-component free amino acid research formulation (citrulline, arginine, ornithine, carnitine, NAC, lysine, proline, taurine, glutamine) in a lyophilized vial, typically 865 mg. Despite the market name, it contains no linked peptide chains — it's an amino acid blend studied for multi-pathway interaction.

What is SHB peptide good for in research?
Its components are individually studied for nitric oxide metabolism and blood flow (citrulline, arginine, ornithine), cellular energy and fatigue (carnitine, taurine), antioxidant defense (NAC), and structural/connective tissue pathways (lysine, proline, glutamine). The blend itself has no direct clinical literature; it exists to study how these pathways interact.

How do you use Super Human Blend?
SHB is supplied lyophilized for laboratory research. Standard handling: refrigerate at 2–8 °C, reconstitute with bacteriostatic water using aseptic technique. We publish a full handling and reconstitution guide. This product is not intended for human or animal use.

Is Super Human Blend the same as BPC-157?
No. BPC-157 is a single 15-amino-acid peptide studied in tissue-repair research. SHB contains no peptides — it's a matrix of free amino acids. They belong to different research categories; see the comparison.

What's the difference between the 865 mg and 790 mg SHB versions?
The 790 mg formulation is the same eight-component formula without NAC (75 mg). Check your supplier's stated composition — labels vary between vendors.
