KLOW
Cosmetic Peptide
KLOW is Prime Time Bio Labs' four-peptide research blend — GHK-Cu, BPC-157, TB-500, and KPV — supplied as a lyophilized powder in a single vial. It expands on the brand's GLOW blend by adding KPV. Each of the four listed components has been studied individually in laboratory and preclinical research; the combined formulation itself has not been independently studied. Every batch ships with a lot-matched Certificate of Analysis from third-party HPLC and mass spectrometry testing. Research use only — not for human or animal use.

PT-141 is the research designation commonly used alongside the generic name bremelanotide, a synthetic melanocortin receptor agonist studied in the scientific literature for its activity within central nervous system signaling pathways — a mechanism distinct from the peripheral vascular pathways studied in other research compounds. Each unit ships as a single-use, light-protected vial with a lot-specific label for batch traceability, and every batch carries third-party testing for purity, identity, and sterility, with a matching Certificate of Analysis available for download. PT-141 is not a drug, dietary supplement, or cosmetic, carries no FDA approval, and is intended strictly for qualified research personnel — not for human or animal use.
Dosage

DSIP
Cognitive Peptide
DSIP is a research-grade nonapeptide supplied by PrimeTime BioLabs for in-vitro laboratory investigation. The compound, widely referenced in the peptide literature as Delta Sleep-Inducing Peptide, is studied for its proposed role in sleep-wake regulation and stress-hormone signaling, with research models examining interaction with GABAergic and opioid pathways. Each vial is manufactured under controlled conditions and independently verified via HPLC and mass spectrometry, with a lot-matched Certificate of Analysis available for the batch listed above. This product is supplied strictly for qualified laboratory research and is not intended for human or veterinary use.
Dosage

Semax
Cognitive Peptide
Semax is a research-grade synthetic heptapeptide supplied by PrimeTime BioLabs for laboratory use. Chemically identified by the sequence Met-Glu-His-Phe-Pro-Gly-Pro, Semax is studied in the scientific literature as a synthetic analog related to the ACTH(4-10) fragment, most precisely described as the ACTH(4-7) sequence extended with a Pro-Gly-Pro tripeptide. Each unit ships as a lyophilized powder in a sealed, light-protected vial, with a lot-specific Certificate of Analysis confirming identity and purity by third-party HPLC and mass spectrometry. This listing is intended strictly for qualified laboratory and in-vitro research use.

Dosage

Wolverine
Healing Peptide
Wolverine pairs two of the most widely studied tissue-repair peptides — BPC-157 and TB-500 — in a single vial, giving researchers a practical way to evaluate their combined activity without sourcing, reconstituting, and storing two separate products. Each is well characterized on its own: BPC-157 for its role in angiogenesis and fibroblast migration, TB-500 for its actin-binding activity and involvement in cell migration and vessel formation. Combining them in one vial is meant to simplify protocols for investigators who are specifically interested in how the two pathways interact rather than running them in isolation. Every batch ships with third-party HPLC and mass spectrometry testing and a matching Certificate of Analysis, so the identity and purity behind the blend are documented, not assumed.
Dosage

KPV
Healing Peptide
KPV is the C-terminal tripeptide of alpha-MSH (Lys-Pro-Val), studied in preclinical and in vitro models for NF-κB signaling reported to occur independently of melanocortin receptor binding — a focus of laboratory research into inflammatory signaling and intestinal epithelial biology.
Dosage

TB-500
Healing Peptide
TB-500 is a synthetic, 7-amino-acid fragment of thymosin beta-4 (Ac-LKKTETQ), studied in laboratory models for its actin-binding properties and role in cell migration.
