6 weeks into my second cycle. Doing 500 primo and 400 prop.
Everything is going well, but I've noticed my nuts are shrinking much faster than they did on my first cycle (750 of sust).
During this cycle I've been shooting 500IU's of HCG twice a week, which I didn't use in the first cycle.
Any ideas on what I can take to maintain/regain normal testicular size?
