Proven History with Supplement
Used product for years with success. I use the original and combine it with Beta Alanine separately to get more effect than Optygen HP.

Great product poor delivery
I think Optygen and First Endurance are great have used it a long time and it works great This is review is for delivery. This never arrived on time or as stated. I even subscribed and seem to get the delayed message. This product has a loading dose and its disappointing to not get it on the date its supposed to be delivered.
