Comprehensive Fitness Product - Getting it to market?

I'm a 26 year old fitness trainer / natural bodybuilder with digital marketing experience. I have an extremely comprehensive slim to muscular transformation which is documented and verified.

Here is a sample of my before after (to give you an idea).

The transformation took place over 1 year and was documented with photos and HD videos along with the dates shown to prove it was genuine and not photoshopped or.. over a longer period.
I have Official Doctors Reports and Official Strength Test Reports to tie my weight gain and strength improvements to dates.

Most importantly I have a Steroid Test Report to prove I was natural throughout and still am to gain trust from my target market.

I have tested the market already and got over 100k views on a Youtube video with huge demand to buy the training routine and diet plan that was used.

My ambition is to create a downloadable product that will consist of training and diet videos along with written content. I am unsure of the best approach and most secure way to deliver the finished product via my site before Clickbank.

I would really appreciate feedback from those of you who have already had the pleasure of monetizing such products. Thank you for reading and for any possible feedback.
