No such thing in pill form. All lies to take your money. PE in my oppion is a waste of time also. A lot of work for minimum to no gains.
1. Pumps will give you a temporary increase and is safe
2. Stretching devices will add length but takes a long time and not practicle
3. Implants will add size, but you have a foriegn object in your penis
4. Fat transfer is a dead technology, fat always reobsorbs and becomes lumpy
5. Dermal fillers are proven. Many here have done that route. But pick a good doctor and use a real dermal filler such as a temporary like juveederm or permanent filler offered by a good doctor.
Pick the best option for you. And consult with someone who has experience.
