Possible a better way would be to look at earning a bit more money on the side. I'd guess you're in the gym enough that you could help out some people for a small fee or paid in supplements or whatever. You could do cheap consults for people who want to know if their training or diet is in check. Have a small mentorship group. Get creative.
From what I can tell you've been at this a long while and people could learn from you.
Example : $20 a month mentoring for when you're at the gym + email, do automated payment via paypal. Basically you're getting paid to talk about something you love to talk about and helping others not make the same mistakes you did when you started off. Help out 5 people, $100 a month into your paypal which you can then spend as you like on supplements :-D.
Do not go gentle into that good night...Rage! Rage! against the dying of the light!!
