Core Peptides

Core Peptides lists 125 SKUs across 102 products on Peptides.SO, with 75 size-labelled listings at a median of $4.30 per mg. Its list-price range is a narrow $20 to $300. The catalog is growth-peptide led (41 listings), followed by cosmetic peptides (21), bioregulators (17), healing and recovery (11), sexual health (9), research peptides (7), cognitive (7), anti-aging (5), weight management (4) and immune support (3). The supplier's own feed splits the range into 103 single peptides and 18 blends; the blend line (CJC-1295/Ipamorelin, CJC-1295/GHRP-2, and a BPC-157/TB-500/KPV/GHK-Cu combination vial) is the largest of its kind among the suppliers profiled in this batch, and 10 listings carried a discounted price at the last sync.

By category, Core Peptides prices below the platform median on growth peptides ($9.70 vs $12.20 per mg, about 20 percent under), research peptides ($4.60 vs $6.68), healing and recovery ($1.85 vs $4.74) and cosmetic peptides ($0.88 vs $1.00), and is level on bioregulators ($3.15 vs $3.09), sexual health ($4.30 vs $4.50) and cognitive peptides ($6.80 vs $6.73). Only weight management ($7.80 vs $6.50) and immune support ($8.50 vs $7.85) run above.

On the 84 size-labelled products it shares with three or more other suppliers, 23 are priced below the median of the other suppliers and 61 at or above it. The cheapest overlaps are in the secretagogue line: GHRP-6 5mg at $20 against a $33.50 median across 44 other suppliers (40 percent under), CJC-1295 No DAC 5mg at $41 against $57 across 58, PEG-MGF 2mg at $63 against $87 across 5, and the CJC-1295 + GHRP-2 10mg blend at $20 against $27.47 across 12. The premiums sit in a few cosmetic and niche SKUs where Core Peptides' pack size differs from the norm: SNAP-8 10mg at $195 against $40 across 42 suppliers, GHK-Cu 500mg (5 x 100mg) at $197 against $50 across 14, Thymalin 10mg at $138 against $36 across 3, and Gonadorelin 2mg at $90 against $54.81 across 22.

The catalog also carries a receptor-grade IGF-1 LR3 SKU and single-vial AOD-9604, Hexarelin, MOTS-c, Sermorelin and Tesamorelin listings; because several blend rows compute per-mg figures across a multi-compound total, researchers comparing single actives should use the single-peptide listings rather than the blends as the comparison basis.
