Nextday Peptides

Nextday Peptides carries 68 listings across 64 catalogue products on Peptides.SO, with growth-hormone-axis peptides its deepest segment at 13 entries. It is a broad general-catalogue storefront priced in US dollars, and its platform listing captures a wide spread between its cheapest and most expensive entries: $40 at the bottom and $1,125 at the top, with a median list price of $90.

Catalogue shape from platform data: the growth-hormone segment covers CJC-1295 with and without DAC (including a 2mg buy-one-get-one entry), a CJC/Ipamorelin blend, a three-way CJC/Ipamorelin/GHRP-2 blend, GHRP-2, Hexarelin, MGF and PEG-MGF, Sermorelin, Tesamorelin and Ipamorelin/CJC dissolving strips. Weight-management research compounds follow at nine (5-Amino-1MQ, AOD-9604, Adipotide, MOTS-c and several lipotropic and carnitine formulas), then healing and recovery at eight (ARA-290, BPC-157, KLOW 80mg, KPV, TB-500 in two formats and a Wolverine blend), GLP-class compounds at seven (Cagrilintide, Mazdutide, Retatrutide, Semaglutide, Survodutide, Tirzepatide), and cosmetic peptides at six, including GHK-Cu in 120mg and 5 x 100mg formats. Smaller segments cover sexual-health peptides, anti-ageing compounds (Epitalon, FOXO4-DRI, NAD+, glutathione), cognitive peptides (DSIP, Selank, Semax), immune peptides (LL-37, Thymosin Alpha-1, Thymulin) and SS-31.

Where Nextday Peptides sits against the platform: 41 of its products are stocked by ten or more Peptides.SO suppliers. At list price, 13 sit below the cross-supplier median, 27 above and one at par. The below-median entries are concentrated in the mid-range: SS-31 at $75 against a median of $111.25 (39 suppliers), Retatrutide at $125 against $176.50 (27 suppliers), Tesamorelin at $60 against $80.38 (93 suppliers), Epitalon at $45 against $59.99 (70 suppliers), the GHK-Cu 5 x 100mg kit at $45 against $59.99, Thymosin Alpha-1 10mg at $60 against $73.25 and BPC-157 at $75 against $92.00 (91 suppliers).

At the top of the range, Survodutide 10mg at $930, FOXO4-DRI at $1,125, Adipotide 10mg at $435, Mazdutide 10mg at $555 and Cagrilintide 10mg at $510 are five to eight times the platform median for the same catalogue entry; pack sizes are not stated in those product names, so treat them as likely multi-vial kits and confirm the quantity before comparing. Every listing was in stock at the March 2026 sync.

Verification status on Peptides.SO: Nextday Peptides is not platform-verified, has a testing score of 0 out of 7 criteria, and has no Certificate of Analysis linked. It holds a 4.0 out of 5 rating from one platform review, and wire transfer is the only payment method captured from the storefront (one of 8 suppliers in the pool listing wire alone). No supplier in the active pool currently documents a testing criterion or a COA on the platform, so request a batch-specific, third-party identity and purity analysis directly before ordering.

Common questions. Where is the platform price advantage? SS-31, Retatrutide, Tesamorelin, Epitalon and the GHK-Cu kit. Why are some entries far above the median? Several GLP-class and longevity listings carry list prices consistent with multi-vial packs rather than single vials; the platform stores the list price as published. Does the supplier document third-party testing on Peptides.SO? Not at present.
