All the new zphc is in bottles of 100. The ones I saw , they have & make spectrum too, so you can sub out either or .
Where did you get this info? ZPHC is ZPHC, Spectrum is Spectrum.
The manufacturers are located in different places. Don't trust different rumors and shops that call themselves official dealers and state that ZPHC, Spectrum, Canada Peptides, Dragon Pharma, Maha Pharma and the others are produced in one factory.
Some shops started this rumor to make their customers waiting for ZPHC buy Spectrum.
Once again, these are absolutely different companies in different locations.
If you want more info, contact official ZPHC via their website and inquire whether they produce Spectrum.
