We carry three manufacturers and stay with them rather than rotating suppliers by price. Two of them put a verification code under a hologram on the packaging, so you can confirm a vial with the manufacturer directly, without taking our word for it.
The three brands in this shop
| Manufacturer | Products here | Strongest coverage | Verification |
|---|---|---|---|
| Bio-Peptide | 27 | growth hormone peptides, muscle, weight loss; the only brand here covering skin and longevity | code under hologram, checked at bio-peptide.com |
| Genheal | 27 | growth hormone peptides and muscle; the ready BPC-157 and TB-500 blend | code under hologram, checked at genheal.com |
| Nouveaux Ltd. | 17 | growth hormone peptides, including 20 mg BPC-157 and combination vials | manufacturer site nouveauxltd.com |
Product listings for each brand: Bio-Peptide, Genheal, Nouveaux Ltd. Those pages are in Polish; the English descriptions of what each group contains are in our shop overview.
What differs between them, and what does not
The molecule does not differ. BPC-157 from one brand is the same fifteen amino acid sequence as BPC-157 from another. What differs is everything around it: vial size, batch documentation, packaging and whether a verification code is provided.
Vial sizes are the most visible difference in practice. BPC-157 comes as 5 mg from Bio-Peptide and Genheal and as 20 mg from Nouveaux Ltd. Follistatin 344 comes as 1 mg from Bio-Peptide and Genheal and as 2 mg from Nouveaux Ltd. A larger vial holds more milligrams, not a stronger molecule, and the concentration you end up with depends on how much water you add.
How to verify, brand by brand
For Bio-Peptide and Genheal, scratch the hologram on the packaging, read the code and enter it on the manufacturer’s site. The answer comes from the manufacturer’s own database, which is the point of the exercise. A code that fails, or that has already been used, is a reason to stop and write to us.
For every brand, the certificate of analysis is the second check and the more informative one. It should state purity by HPLC, identity by mass spectrometry, the batch number and the test date, and carry a key you can verify at source. The full procedure is on the page about checking your product.
Why we do not rank the brands
We are not going to tell you that one manufacturer is better than another, because we have no data that would support it. What we can tell you is what each brand actually supplies here, what vial sizes it uses and how its documentation can be checked. Those are facts you can verify, and a ranking would not be.
Frequently asked questions
Which manufacturers do you sell?
Bio-Peptide (27 products), Genheal (27) and Nouveaux Ltd. (17).
Which brands have a verification code?
Bio-Peptide and Genheal put a code under a hologram, checked on the manufacturer’s own website.
Is one brand stronger than another?
No. The same peptide is the same molecule regardless of brand. Vial size, documentation and packaging differ; the sequence does not.
Why do vial sizes differ between brands?
It is a packaging decision by each manufacturer. A 20 mg vial contains four times what a 5 mg vial contains, and the concentration after reconstitution depends on the volume of water added.
