This reasoning is common, but faulty. For just one example, if you have an allergy to something, more exposure to the allergen causes increasing sensitivity. This is why if you have an allergic reaction yku should absolutelt avoid it in the future - because it will be worse next time.I doubt it’s Epi-Andro. I was on AndroHard for 3 weeks without a rash and then started the Stano-Plex a week or so ago.
Also, sometimes things take time for a reaction to become bad enough that you notice it.
Not saying that it IS the problem, just that it wouldn't be 100% for certain.
