Like some have mentioned PCT can be a roller coaster and especially with out the "bullet-proof" feeling you get while "on" your mental out looks plays a big part in your recovery. With that being said, I've found that Sustain is (for me) the best mood enhancer in and out of the bedroom. Other things might work to actually provide you with an erection but as far as "wanting it" is concerned, Sustain seems to do a very good job. Unleashed definitely helps make you hard so I'd combine the two for added benefits. Not to mention that Unleashed has the added benefit of mimicking Proviron in it's SBHG binding properties. HCGenerate I used during the last 5 weeks of my cycle and was happy with the results.
Good luck with recovery!
