Titan penis growth gels, containing 12% dht are best suited for those starting off, no sides and very little systematic effects you can stack this with pge1, or titan xl to increase your gains.
Titan 20 can be stacked with the same products but it is stronger and some feel flushing when using it, its very effective but you must stretch after use.
Titan 35% dht gel is currently the strongest version we do though we are working on a new version that will be even stronger, its very potent and very effective for growing a beard, your penis, clitoral enlargement or for gyno reduction.
For trt purposes I suggest titan 20%
I hope this helps to clarify a few things and make it easier for you guys.
Kindest regards RS
