NR (Nicotinamide Riboside) Converted to NMN, then to NAD+ Well-researched, oral bioavailability, generally well-tolerated Requires enzymatic conversion, individual response may vary NMN (Nicotinamide Mononucleotide) Direct precur…
Let's break down the most common p21 storage conditions and their general implications. This table offers a quick reference for making informed decisions in your lab, especially when considering the long-term viability of your va…
DSIP GABAergic modulation + SCN regulation Increases slow-wave sleep 20–30% without suppressing REM (animal data) Proposed SCN phase-shifting effects; limited human validation 1–2 small uncontrolled trials; no Phase III data Mech…
Direct antimicrobial activity 6–48 hours CFU reduction of 90–99% in bacterial cultures; fungal growth inhibition CFU plating, MIC assays This is the fastest LL-37 mechanism. Membrane disruption is immediate and doesn't require do…
Kisspeptin-54 Restores pulsatile GnRH secretion via GPR54 activation 10–20× increase in severe HH (clinical trial data) Yes. Enhances endogenous signaling Hypogonadotropic hypogonadism, hypothalamic amenorrhea, idiopathic oligozo…
Different NAD+ precursors produce measurably different outcomes depending on dose, timing, and metabolic context. Here's how the three primary precursors compare across key research parameters. | Precursor | Cellular Uptake Mecha…
Once daily (single injection) 4–6 hours 6–8 hours post-injection 12–18 hours (declining) 2–8°C for 28 days; freeze-thaw degrades potency Suboptimal. Peptide levels drop below effective threshold for >12 hours daily, reducing cumu…
Oral NAD+ (direct) <5%. Degraded in GI tract before absorption 250–500mg daily Minimal. Poor oral absorption limits CNS delivery Not recommended. Most NAD+ is broken down before systemic circulation Oral NR (precursor) 40–60%. Co…
Third-Party Testing Frequency Quarterly or 'as needed' Every batch before release Every batch, plus post-production retest at 6 months Batch-specific CoA with chromatogram published online Consistent quality requires per-batch ve…
Acute Performance 20mg/kg 2 hours pre-activity Single dose Immediate oxidative capacity increase (70% in Scripps study) Best for proof-of-concept studies; not sustainable long-term Sustained Training Enhancement 10–15mg/kg Daily,…
Accredited research supplier (Real Peptides) Lyophilised white powder, vacuum-sealed glass vial Third-party COAs with lab name, accreditation number, traceable batch ID HPLC ≥98% + mass spectrometry confirmation of 848.81 m/z mol…
A 2024 analysis of peptides purchased from unregulated online vendors found that 47% contained less than 80% of the stated active ingredient. And 12% contained no detectable peptide at all. When you're working with research-grade…

Neuropathic Pain (CCI, SNI) 75–150 mcg/kg SC daily CT2 (early rest phase) 45–90 minutes Delta-opioid receptor upregulation + microglial IL-6 suppression Most robust evidence base; 40–55% reduction in mechanical allodynia in publi…
25–50 mcg Minimum effective dose in early animal studies Mild reduction in sleep latency, minimal slow-wave sleep increase 7–14 days Subtherapeutic in most human protocols. Used primarily for dose-response characterization 100–15…
VIP (Vasoactive Intestinal Peptide) 2–10mg 2–4 doses per day 2–3 minutes VPAC1, VPAC2 Requires frequent dosing due to extremely short half-life. Once-daily administration fails to maintain therapeutic tissue levels beyond first h…
