From some of my readings tonight, CMC appears to be an
HA alternative, but a lot "newer" on the cosmetic scene, relatively speaking. Much like
HA, depending on brand/formulation, you'll find differences in firmness, longevity, etc. If you choose the CMC route, I implore you to start a Progress Report here because there simply isn't any sufficient data for its use in penile augmentation. How it truly compares to
HA in all the "check box" categories is just hard to say at present time.
Having read every post on the forum and in many discussions with my readership through private messages & emails, I'm convinced
Hyaluronic Acid (
HA) is the best "starting filler." It boasts both being temporary and reversible, making it like the "tattoo you won't have to regret." It occurs naturally in our body making it the safest non-surgical filler option on the market. Lastly, almost every Sponsor here offers it, so there are plenty of quality options depending on your region.
Fat is also safe but technically a "surgical" route - if done right (not to overfill in order to ensure proper vascularization + sufficient quality fat from harvest site) by an experienced physician (Dr.
Carney would be my recommendation here), free fat transfer remains a viable option. Also has a strong safety profile due to it being your own tissue.
PMMA is permanent and
Removal can be invasive. That said, it's shown to be remarkably resilient and efficacious --> guys have been getting it injected in their penises for over a decade and reports here show that no one's
Dick has fallen off yet, so it remains the most effective non-surgical permanent solution available.
Fillers can sometimes be mixed yes, but I'm of the camp of trying to stick to one if possible. Also depends on the fillers used and the comfort level of the performing physician. You have a great starting size, I'd say 1-2 rounds of filler treatment and you'll have a hefty unit. Good luck.
