BPC-157 vs Thymosin Alpha-1

What is BPC-157

BPC-157 is a synthetic chain of fifteen amino acids - Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val - derived from a partial sequence of a protein found in human gastric juice. The name stands for body protection compound. It is made by solid-phase peptide synthesis, and laboratory research in cell and animal models has examined its interaction with angiogenesis and growth-factor signalling pathways such as those involving VEGF. That literature is preclinical.

Celyfe carries BPC-157 at 15mg per 3ml cartridge in three pens: the WOLVERINE Pen (with TB-500), the GLOW Pen (with GHK-Cu and TB-500) and the KLOW Pen (with GHK-Cu, TB-500 and KPV). Its molecular formula is C62H98N16O22, 1419.5 g/mol, CAS 137525-51-0.

What is Thymosin Alpha-1

Thymosin Alpha-1 is a peptide originally isolated from thymus tissue, the organ where T-cells mature. The Celyfe compound library classes it as a peptide and lists its mechanism as a peptide studied in immune-modulation and T-cell research. It is marked as a regulated compound, so its library page carries the educational banner and uses informational framing.

Thymosin Alpha-1 is not related to TB-500, despite the shared name. TB-500 is a fragment of thymosin beta-4, an actin-binding protein; Thymosin Alpha-1 is a different peptide from a different thymosin family. No Celyfe pen carries Thymosin Alpha-1.

Key differences

From products.ts, the guides and the library's classification fields:

• Origin - BPC-157 is derived from a gastric juice protein sequence; Thymosin Alpha-1 was isolated from thymus tissue
• Length - BPC-157 is fifteen residues; Thymosin Alpha-1 is a longer peptide
• Research system - BPC-157: peptide-signalling and angiogenesis models; Thymosin Alpha-1: immune modulation and T-cell function
• Mechanism label - BPC-157: synthetic pentadecapeptide used in peptide-signalling research; Thymosin Alpha-1: peptide studied in immune-modulation and T-cell research
• Celyfe pens - BPC-157 is in WOLVERINE, GLOW and KLOW at 15mg; Thymosin Alpha-1 is in no pen
• Status - both are regulated compounds; both library pages carry the educational banner

Which Celyfe pen carries them

BPC-157 is in three pens, each a pre-filled 3ml cartridge with 300 clicks. The WOLVERINE Pen pairs it with TB-500 at 15mg each (30mg, 0.100mg per click). The GLOW Pen adds GHK-Cu at 75mg (105mg, 0.350mg per click). The KLOW Pen adds KPV at 15mg (120mg, 0.400mg per click). All three are on sale now, alongside the NAD+ Precision Pen.

Thymosin Alpha-1 is not in any Celyfe pen. All Celyfe pens ship pre-mixed and cold-chain, are refrigerated at 2 to 8 °C on arrival, must not be frozen. Third-party HPLC certificates are published for the NAD+ and WOLVERINE pens; GLOW and KLOW certificates are being re-issued. Every Celyfe pen is supplied and labelled for laboratory research use. Nothing on this page is guidance on use in humans or animals.

How they fit together

They sit in different layers of the compound library. BPC-157 is carried in the WOLVERINE, GLOW and KLOW pens; Thymosin Alpha-1 sits in the immune-support layer with EGCG, quercetin and zinc and is not in any pen.

The guide to research peptides explains what the two have in common: both are synthesised to a defined sequence, both are typically characterised by HPLC for purity and by mass spectrometry or a reference standard for identity, and both are supplied under the research-use framework described in the guide to UK peptide law.
